why hasn't anyone mentioned timing? Set base timing and work your way out by diagnosing the problem. Your issue might be the tps but even when it's close it will run. When you replaced the afm and the ecu among other parts did you replace them with matching part numbers for your truck? Or did you just figure they are all the same? Better be damn sure they are or you are just chasing your tail. What kind of plugs did you put in it? All the information you need in regards to what you have done should be posted.
Are the things you replaced used parts or did you buy new?




Fuel filter
Open circuit relay
Have tried 2 differnet computer Did the parts numbers match on this?
Have tried 2different afm Did the part numbers match on this?
Have replaced tps (not 100% the adjust is correct) Again part numbers!
Head gasket This is major. Did you replace the head gasket only what all did you do when this happened? Valve job head resurfaced? ect ect?
Coolant temp sensor
Vaccum leaks How did you check for them?
Trottle body cleaned
Valves adjusted What did you adjust them to?
Cap
Rotor
Plugs an wires
Coil
Cleaned injectors and changed orings
Fuel pressure regulator

Feel free to get all the little tid bits out so we can see the puzzle you are working with. When did this start? Was it gradual getting worse over time? Have you done any questionable wiring in your truck? What temp does your truck run at? when running does it do it more hot or cold?

 

I already did thanks man !!!

And all the parts are new besides afm and ecu
I think i got the tps set now and i accidentally put pressure on the injectors while looking for vaccum leaks and when i put pressure on the injectors with a screw driver i noticed two of the injectors were leaking only when i put pressure on them ??? Kinda werid. But i had to extras laying around i put them in and it ran wayyyyy better but still has a slight miss im ordering new injectors tomorrow . Is there any good upgraded injectors anyone recommends??? I hve a 9 inch lift 36s the extra power would be nice


As far as wiring no everything is the same as ive been running it for months and it gradually came along and then got really bad. Seapping the injectos helped alot though.

Truck runs 175ish-190 max

I pulled valve cover, timing is still in the same spot as when i replaced it to do head gasket

I went mostly with all OE parts im running ngk 1233 plugs ( im pretty sure that the number they were the clowstest OE plugs i found. I work at advanced auto parts lol )

But like i said im ordering new injectors and hopefully that fixes my problem if i knew how to upload vidoes on here i would show yall.... And good upgraded injectors anyones tried ???

Thanks !!! Happy 4th !!!!

 

Does anyone know what a stock 22re injector (cc's) are ???

 

This doesn't make sense. How are you setting your timing? How do you go about setting it to the right spot?

 

Well i set it when i did the head gasket with the dot on the cam gear straight up and thats were it is still hasnt jumped a tooth or anything thats what i ment by the timing is still in the same spot, ran fine like that before so i never messed with it. So its not a timing issue like i said in one of my last post the injectors were leaking when u put pressure on them so i ordered new ones. Can someone tell me hiw to upload a video ? And ill show yall

 

You're looking for 5 degrees BTC for a 22RE. If it's a 22R, I don't know the specs.

 

Yodalife12 is mixing cam timing with ignition timing. Ignition timing is what he should check. Easy to do, and probably the first thing you should check with any engine problem.

And there's probably nothing wrong with his injectors; they're solid machined blocks and are not going to leak with finger pressure. But they're sealed to the rail with simple o-rings, and yes, those could leak if you push on them. If it were me, I'd just get the o-ring kits (top and bottom of each injector) and save about $800.

 

This is what I was getting at. He needs to set his timing right to get a base to start actually finding out what is wrong with his truck. Also need to make sure the part numbers match on the ecu and the afm before he goes any further. Unless he wants to keep swapping parts,spending money, and wasting time. So far the shot gun approach has yielded him a truck that doesn't run with leaky injectors and an empty wallet. Good luck.

 

I just swapped the ecu amd afm to see if it was the problem im back to my orignal parts now. An i said it like 3 times its not the timing. And the injectors are old anyways so im just gonna replace them and all orings with them also and see what happes then.

 

You seem to know what you're doing. Good luck with seeing what happens.

 

Yes, we read that. What we're trying to tell you is that method can set cam timing, which has very little to do with ignition timing. Which is often a cause of the problems you describe, and very easy to check (not by removing the valve cover). But it's your truck ....

The injectors on my truck are 20 years old, and work perfectly. It's not like they're a maintenance item. But if you have the money and time, go ahead. Just don't be surprised when it doesn't change anything.

 

I didnt join this forum for people to be rude but thanks

 

No rudeness implied but when a member opens a thread with the title
"93 pickup need help asap !!! Please !!!!" People are going to respond with help. You asked for help. You are getting help (even if you don't want it). What you are doing to your truck obviously isn't working.
"you can lead a horse to water but you can't make it drink"

 

Ok lets start over timing has been check and is on point i did it just like the video . Its not the timing. The injectors were leak probably the orings but i wanted to upgrade anyways . Any other suggestions ?

 

cool, glad you checked it. What is it set at?

 

Right in the 4-6 range my mark is kinda hard to see bc of my intake pipe but its pretty much dead on.

 

Update : i went ahead and rechecked timing and it was about 7 so i reset it 5 to be on spec BUT i was reving it alittle an while watching timing with the light, it goes past zero ( the opposite way of what your supposed to set it at ) then comes back to about 5 and when i comes back to 5ish is sounds better then as i rev it more it clears up around 4 grand ???? Is that how its supposed to work ?? I though it was only advancing when reving ?

Im lost.... It also pops out of the exhast/intake if i rev it fast and hold it

Not enough fuel ????

 

Are you checking the timing with the test jumper installed? It should be at 5*BTDC with the jumper, but when the jumper is removed it should go to around 10-12*. What does your timing go to when you remove the jumper?

 

I actually didnt pull it out when i tested it damn it. Ill go recheck

Knock sensor maybe?

I sware its not got enough fuel to it... I just put a new pump in it too im gonna get a pressure tester tomorrow and check that was well.

 

UPDATE i rechecked timing jumped te1 and e1 and checked it it was at 5 then unplugged them and nothing it stayed the same, no advance , no idle up nothing just the same as it was ?????? Whats that mean ?
