Truck: '92 pickup w/ 22re

Problem: Thursday I went to a friends house and parked in his yard, shut off my truck as usual. We left in his truck and upon my return to go home, I get in my truck and it won't start. It cranks, or should I say spins - but doesn't start, doesn't even burp.

I can't see it having jumped time or anything, I have not done a compression test for lack of a gauge.

Things I've done are..

Tried starter fluid in the intake

Checked the plugs, got spark and the plugs look fine.

I've checked the air sensor, manual says it should read between 200 and 400 Ohms, it reads 300.

Checked the fuel, got pressure and the fuel filter flows fine.

Reset the computer.

Checked all connections, vacuum lines, etc. nothing amiss.

I'm probably forgetting something. It's been a stressful couple days.

So I googled around, couldn't find much of anything I hadn't already done or isn't applicable to my truck.

Any ideas fellas?

pull codes? i'm sure its got one. you may have the same or possible clsoe issue i have.... right now my truck has fuel spark and everthing and won't start. i pulled the code and it gave me a code for rpm signal/igniton signal. I plan to trouble shoot it in a few days but i am prolly in need of a pick-up coil which is in the distributor. you can trying cleaning the inside of your distributor components and or beat on ur ignitor and see if that helps.

Kaydon

You reminded me of some things.

I've tried both a different coil, and igniter. Neither did anything.

I don't have a code reader, do any of the auto parts stores still lend those things out?

Kiroshu

Blah brain cramp theres 2 terminals you jump in the diagnostic plug to get the engine light to blink you the code....... "Someone help me out yota tech!" Yea you might can look that up online i forget but if you get the code out let us know or look it up and tell us..... alot of parts stores do have code readers but i don't think they do for OBDI vehciles like ours....... you know how to read the engine code light blinks right? You need a piece of wires or paper clip to jump. The light will blink a certain number times to give you a number. It pauses 1 secs between each number and about 3 secs between each code.

Kaydon

Ah ha! the paperclip trick. I didn't even think of it!

I'll try that tomorrow and post what I find.

Appreciate it!

weaselman

doesnt the truck have to be running and idling to get a proper reading for codes??

becuz if i check for codes and my trucks not running. i get a few codes.. but as soon as i start it and let it idle... i have no codes..

Magnusian

No, you want the engine off, it won't throw codes while it's running, just give you a solid CEL (if you get a CEL). You want the engine off and the key in the IGN position. If you're getting codes when your truck isn't running you should probably look into them. Your lack of codes while idling does not mean everything is ok.

Kiroshu

to pull codes from an OBDI vehciles engine off key on.

Kaydon

I tried the Fp to B+ terminal jump, couldn't seem to find which other ones to try. No dice. Should I try the TE1 and E1? Wasn't sure if those were it or not.

Is this timing related? But if so, how, considering how I came upon this issue..

Team420

to pull the codes u need to jump te1 and e1. fp and b+ just power the fuel pump.

Kaydon

It's not giving me anything so I figure I'm doing it wrong. What's the trick, if there is one?

Kiroshu

When you jump those terminals with the key on your engine light should blink. It will blink a certain number times to show a code let us know the number blinks if any. It will pause about 1 sec between numbers if its a 2 digit code and pause 2-3 secs between codes.

Team420

if u have no codes stored it will just blink continuously.

Kaydon

I'm using a piece of copper wire inside the terminal slots, but I'm not sure if it's making the connection. Engine light shows up, but doesn't blink.

Team420

just about any wire should do.... sure u got the right terminals? Also ...make sure u push the wire down into the slot... sometimes its in there but not making any connection.

Kaydon

Okay, yup. Wasn't making the connection.

It blinks 3 times quickly, pause, then once.. Code 31?

Team420

code 31.....
Volume
Air Flow
Meter
Signa


At idling, open or short detected continuously
for 0.5 sec. or more in volume air flow meter
circuit.
• Open – VC
• Short – VC – E2

• Open or short in volume air flow
meter circuit
• Volume air flow meter
• ECM


heres the link to check it out.

BTW.... If u jump the terminals u did before fp and b+, you should be abler to get her started.

Kaydon

http://4crawler.com/4x4/CheapTricks/AFM/index.shtml I was looking there.

Jumping those terminals isn't getting her going, unless I again failed to make a good connection. And/or my battery is weak after the past couple days.

Kaydon

WTF!

So I grabbed a new air flow meter this morning, no dice.

Done everything I can think of...

It won't start.. Why?

Team420

Did u get a NEW vafm, or a used one? If its new, and u still have the issue (code 31), then u likely have a bad wire somewhere or bad ecu... its unlikely the ecu... but it is possible.
