yeah mark I look at that interior and all I think about is our lexus es300 we used to have god I loved that car, everyone said it was just a fancy camare they couldnt have been more wrong, anyway I just hope I didnt overlook somthing important on this thing but man it seems realy solid and sound and is realy clean for the age. the sold on the window kinda made me laugh I think he did it just to make regina feel good, and it did LOL.

 

One more time, .... did she get the Email, Jason?

 

sorry man I ment to answer you earlier yes see did.

 

I know, she's multi-mental-tasking on overload due to the new 4WHEEL-FAMILY MEMBER! lol. Wasn't worried about it for me, just for her, as she said, "time limits in play", ya know?

 

ok guys made it out to work on the runner for a few today and this is where Im at.
pulled valve cover brought #1 to TDC
checked dizzy, the boy had it dead on, proud of him.
changed AFM and coil igniter asembly for known good parts [thanks terry]
tried to start, no change
checked for spark which it has.
checked for fuel at the return line good stream while cranking.
pulled codes again getting a 6 and 11 just like before.
next step check the TPS if I can figure out how.
? the switch code mentions the a/c switch I dont understand what that meens and I dont think its the problem becouse it has ran the way it is with out the the compresser hooked up[its not there any more].
Im doing the best I can with the POE list. and if the TPS tests ok Im really gonna be lost. but I will keep trudgeing along till I get it.

news on the new runner still not home unbeleiveably we were to bust today to go check and see if it was ready heading that way first thing in the morning.

 

couldnt leave it alone went back out a checked the TPS checked out ok at this point Im lost .

 

Wow, ... this is really leading me toward the "something electronically wicked this way comes" movie.

Hmmmmm, ..... Maybe time to test things at the ECU homie? I would venture to say might be your best bet? EEEK, what a PITA this thing is being! There are many tests at the ECU that could tell you if wiring is failing you between components and the ECU IN the harness. The ECU IS testable....but not much, as I remember(could be wrong on that). I do have an 87 ECU you can try out, granting Terry whom I think is closer might have? lol. Let me know, just for the heck of it, right?

You checked all those connections at the ECU as well, right? I mean, sure, very doubtful, but why not, right? It wouldn't even turn over or have fuel or whatever(depending on which plug is unplugged), but I'd check it and rule it out and put it in the POE just for the hell of it.

I actually tried to start without my AFM plugged in a couple times..... wish it was something that easy for ya.

IS it STILL popping?(backfire?) Is it trying to fire up? You verified HOT SPARK????? Replacement Ignitor or not, ya know? Coils go bad as well.

Did you test the 'SECONDARY COIL' in the dizzy like I said? That's bad, YOU'RE DOA!

Sorry man, but don't give up! I think I've earned the right to say that, eh? lol.... but seriously, I KNOW IT SUCKS!!! I'll be thinkin some more. Can you take some pics of the engine hookups, just so I can take a peek? Not second guessin ya... and everything pretty much has it's place, but why the heck not, right? Dizzy connector, coil pack connector, etc?

 

Hey mark Im with ya I think its time to start testing at ther ECU I will have to do a search and see if I can find a pin diagram.
not sure how to check the secondary coil either but I get that info found as well.
its not poping or anything anymore seems like the longer it goes the further it gets from running ya know.
be glad to get some pics up if it will help I will do that first thing in the morning.
man I was so stoked when that box from terry showed up I thought theres the parts that are gonna get this thing running, when it didnt do anything huge let down, again thank you terry. any sugetions you guys got bring em on.

 

Was really hoping you would have it running on this trip in. I talked to yo lat nite about the TPS, and just thought of it this morning. Try disconnecting the TPS and clearing the codes before starting it. Maybe the TPS codes have got the computer confused.

I would try checking the coil in the distributor and look for any loose connections and even make sure some mouse buddies didnt find there way into some wiring.

I am starting to lean toward the computer myself. It will be Monday before I could get out to the 86. The 87s computer went to my friend along with the motor.

I have my Army thing this weekend, but I do have a friend in there that is a Toyota mechanic and will see what he has to say. I know this has to be a big let down, but it will be a good learning experience for all us. You are going to be the 22re Guru when this is all done.

 

Haha thanks Terry, have to run some errands this morning, and then I'll get back to trying to find a test for the secondary coil, I searched last night but didn't find anything so if anybody knows what I need to do plea point me in that direction. Thanks for stopping by guys.

 

HELP PLEASE !!!!!!!!!!!! I dont have a FSM and cant find one on line and I dont know how/what to test.

 

try here http://www.ncttora.com/fsm/index.html

 

thanks jerry working on it now.

 

For the Secondary Coil, unplug the connector right at the dizzy, insert the multi-meter into the plugs on the dizzy side and testing for resistance on the "2K" setting you should read "140-180ohms", .....If you read something FAR lower, I would imagine the resistor is toast, and if it's higher, ......not sure what the heck that would mean! lol. << Resisting too much? lol. Anyway, mine was like 161..... so I moved on, ya know? But that doesn't mean that the Dizzy isn't bad, .....it's just rare I guess.

Find anything out? Hoping for the best, buddy!

 

You musta lost signal.... S'all good. Now, GET CRACKIN! lol.

Do yourself a favor, as I was saying on the phone.... DO NOT chase your tail, NEVER! Refuse to when people suggest it, snarl if they insist! hahahaha, jk.... but you get the point. There is a Process of Elimination for EVERYTHING on this rig... Even my CAM, MAN, ....would've gotten there eventually if I'd stopped insisting it was the EFI system/IGN System relationships, etc, ya feel me?

1. Pull the CSI and VERIFY THERE'S FUEL! (NO WAY, would be my guess, since it should AT LEAST give you a pop, considering you've verified HOT BLUE SPARK! Right? lol

2. Once you find no fuel coming from there/find fuel coming from there, next step,

3. etc.

Si? lol. 2. for me would be checking the injector time switch and maybe injector resistor just for the hell of it, maybe testing at the ECU at No.10 and No.20 pins, verifying that juice IS GETTING THERE. A noid light might not be bad for #3. But that's up to you, ..... Injector Resistor maybe? My guess is it's fine, and for some reason, like you recognized when having rich issues, then NO START, finally, before rebuilding........ Either the Injectors, ECU or SOMETHING went haywire before you started your build. Yep>>>> IF YOU GET NO FUEL COMING OUT OF the CSI....... go RIGHT TO THE Cold Start Injector Time Switch. Those tests are even in the Haynes, ya know?

Hope you're out there now GIVING IT HELL, MAN! OOHRAH! lol.

Let me know if there's anything I can do, k?

 

ok so the strangest thing just happened, pulled the CSI out of the plenum to check for fuel thru the injector and pop Im tryin to run for ya buddy, put the injector back in and nothing unhooked the injector wire and she ran sorta couldnt get it to rev just sort of a week idle, so any ideas now.

 

Holy Crapula! lol....

Hmmmm, .... trying to think of what could be goin on there, ..... I'll give ya a call, but first, tell me where your Idle/Air Adjustment Screw is set at? It's not all the way in, IS IT? If not, screw it all the way in, then out 3 full turns. WHO CARES if it idles high(not likely, but why not, eh? lol).... we just wanna see if that's an issue. Also; Initially, the truck runs Air through the IACV and Open Loop Setting on the Fuel. .... The IACV, pretty sure, bypasses the throttle body by pulling in air BEFORE the flap, right? I wonder if the thing is TOTALLY closed up? You could pull the front and rear air hoses off it so you can shine a light from behind it and see if you see a light when it's cold(when warmed up the coolant temp will close that arm in there and cut off all air but A TINY hole the size of a pen tip. But while it's cold, you should see light in there)<< THAT WOULD NOT stop it from running....it would only stop the 'IDLE UP' function,..thus, I said, "Open up the Idle Air Screw a lil if it's not".

Far as the CSI , WOW, ...ok, so, I wonder does it become grounded by the bolts, or is it grounded through the connector, elsewhere(intake nut ground, etc?) You could very well have an issue with the CSI time switch,..... didya test it? Sounds to me like either your connecting of the CSI is causing a short, via being ground out or something, or maybe the CSI time switch could be causing a failure of the injectors to fire? (Don't think that's possible, lol)

it shouldn't take SECONDS to burn off any amount of fuel that is in there.... and YES, it would smoke like a pig, ...but sure, maybe your CSI has been staying on ALL THE TIME, even before you'd rebuilt, which makes things pretty rich/mileage suck, right?

Edit; Couldn't get it to rev, eh? Hmmmm, ..... we'll get this(you will, specifically! lol) Jason, ....hang in there. Gotta run some errands, but I'll try to call you shortly, k?

PS> Is it possible that the timing is WAYYYYYY retarded or advanced? (Dizzy should be more toward the top/turned clockwise /then backed off about 3/8" of space between the nut and end of pivot...make sense? lol) Just to start, anyway.

 

Ok, after talking with you, I just wanna type out what we discussed to keep a good record for P.O.E., ya know?

1. You disconnected the electrical connector to the CSI and for the first time, it actually ran for around a minute.
.....a. From there, we decided you should first un-mount it from the plenum, wire connector disconnected and turn it over and see if it's shooting fuel disconnected from the Voltage(Would clearly be an issue, but you could move on to other things from there while waiting for the CSI to be serviced/replaced.)
.....b. IF it's still shooting fuel in there, while disconnected from voltage, you might want to move on with a Noid Light or other like-minded test to verify whether or not your injectors are firing AT ALL/whether they're getting VOLTAGE at all/etc.(Obviously, if they're not getting voltage, they're not firing, lol... But then you'd need to, possibly, eventually rule out "Did my resistor blow out long ago, thus my major issues before the build with richness, etc., and subsequently blow out my injectors?") Also... (Not sure it could run for a minute by just the Cold Start injector>>> But you said it would not 'REV', so maybe it's just enough fuel to keep it running, but obviously, if the injectors are not firing, and seeing that they run in junction with the RPM signal, ..... maybe it's enough to keep running, BARELY, but not enough to 'rev'/respond by throttle... Maybe that's exactly what's happening??? lol......)

2. Check your Cold Start Injector Time Switch readings via the FSM or Haynes(If the CSI is pumping even disconnected from voltage, the CSI time switch is OBVIOUSLY not causing that, but it could STILL be suspect as to whether it's working or not)

3. Check your Air/Fuel(Idle-Air)Screw setting and make sure it's not screwed all the way in(Doubtful, but check anyway, then turn it all the way in and then out 3 full turns to start with).

4. Check your Dizzy's timing-placement in relation to what we spoke on... Just get it close.(Doubtful if you went all the way clockwise/advanced, after trying all the way counterclockwise/retarded, that it's the issue...but just get it close anyway, right?)

5. Disconnect the TPS connector AFTER trying all the other stuff out. Sometimes a refusal of Throttle Response and bad behavior by the 'go-go' feathering.... CAN lean toward TPS to some degree, but it would have to be 'destroyed' or WAY off on it's settings I would think. STILL, ...try it, as it SHOULD RUN at ECU/Default settings when disconnected, allowing the injectors to still fire, etc.

 

ok mark checked the CSI like we discussed, no fuel while unpluged whew.
checked CSI timer checked ok again whew.
had the Idle screw out a good ways already but set it like you said.
checked injector resister just couse it was there lol checked good.
put all back together and it only tried to start.
on a gut fealing pulled the dizzy and advanced it one tooth.
vroooooom run idled a little better revs but kinda stutters thru it thats the best way I can explain it, its all better than the last time I was home still rich but not as bad and still have a check engine light. trust me Im stoked to hear it run but lets be honest there is no magic in this what ever caused this head ache is still there because all I did was test stuff, so kinda back to square one but at least it has the potential to run just worried about it pulling this again.

thanks for the time on the phone mark.

forgot to add a few things 1 had open the throttle some to get it to even try and fire, i meen when first cranked it would try and then nothing open the throttle and the stumble stumble run. there was somthing else but I cant remember now.

also wanted to let you guys know alot of the running I have been doing this time involved a new job for the wife and I, we will be starting towards the end of the month, still driveing truck but will be able to get home way more often, and not have to drive 300 mls one way to get our truck. hate to change jobs but we cant keep up the no time at home thing so thats that just wanted to let yaal know.

 

My Pleasure, ....so now you know;

1. Injectors are Firing
2. CSI is not 'running on' without voltage(stuck open)
3. Might have SOME issue with the connector to the CSI
4. Time Switch is working(or at least ohmed out ok.... But you still need to check it again later once it get's WARM, not just at cold, ya know?)
5. Dizzy backed up a tooth WORKED??????????

>>>>>> DUDE, ....I gotta say, again, ....TIMING/IGN-System, COULD be related. Hopefully you're chilling for the rest of the night, ..but YOU WILL get this!
