I figured I got lucky with my truck since it's a '94. The only electronic problem I have is the ABS chip is crap from the factory and the local deal told me it's not a recall even though I got a letter on it. Of course, I threw the letter away because they are supposed to have a copy of it and now I have to get a copy of it to rpove they don't know what they don't know what they are talking about. I hate taking my truck to have work done. It's so expensive. The local charged me $110 for front brake pads and check the rear. Oh, and it only took him 2 hours to do it! lol... that was the first and last time my trucks been in a shop...

thats a little tight on the brakes. 75 to 80.00 will get you a brake job around here. you said something about water, its not getting in the computer is it?

We had the same thing happen in a 98 dodge caravan. Went through mosto f the same things you've done. What it came down to was the computer was loosing communication somewhere within the wiring harness. They pretty much completely gutted the van and replaced the whole harness. Started right up and never had a problem sense. The tech wracked his brain for about 4 or 5 days before he decided all that it could be was the harness.

I'm not sure if that encourageing or not Firebird. I appreciate the input though.. I'm hopeing it doesn't resort to that...

It doesn't look like it. the computer is up under my dash and this leak is on the floor right at the seal somewhere. It would ahve to work real hard to get in there...

just to let everyone know, my truck is warming up as I speak in hopes that it will screw up so I can test it... If not, I guess I will just have to wait till morning...

go figure, my truck won't break down when I want it to.... oh well, theres always plenty of times when I don't want it to...

next time it stops start checking the harness for continuity. Not unless the regulator is shot in your alternator and it's frying stuff. when it does run is it charging at 14.4 or less? Wife's grandam's alternator went bad and her lights were flashing, bells were dinging, and door locks were flipping on and off.

my volt gage usually runs aroufn 12 to 14. Lt1 posted the checklist for me and thats what I'm going to work on. If I don't find anything there, I will start on the harness.

just to keep everyone up to date. I havn't had any luck working on it this weekend. I figured that I will end up waiting till next weekend because I am going to be out of town From Wednesday till Friday night. Maybe I'll get a chance to work on it when I get back.

Since it's been a week since I posted last I figured I'd post to keep it alive... I made it back from my trip on Friday night and started running the truck this morning. So far I've had no problems. I tried to get it to not start over the weekend but just letting it warm up didn't do it. It's now been about 15 miles on and off throughout the day it it still starts up... Again, I'll keep everyone posted and I appreciate the help. Lt1s10- eventually I'll get a chance to get a better idea as to whats wrong. You're diagram you posted is great. I'm sure it will narrow the problem down... Thanks again

I have narrowed the problem once more!!! I figured once I started to brag about it working, it would shut down on me... I think my truck likes to be home, so far everytime it's broken down, it has been at home. Anyway, went home for lunch and when I went to leave, it wouldn't start so I got my chance to use the info Lt1s10 gave me... No signal to the injectors, unplugged the 4 pin connector to the dist. and got nothing out of it with the key on. Next step, pull the computer (which was laying on the floorboard anyway and check pin A9 or A16 with the key on and I had a light. Solution: faulty PCM or connector... I'm 99.999% positive it's not the computer. I'll tell you why... After I checked the two pins, I plugged it back in and pushed on the wires to make sure they were makeing a good connection and it fired right up. Any solutions on my next step? At this point I'm not sure if it's the connection or the harness itself. I doubt it but could it be the chip? If it is just the connector (crosses fingers and toes), how do I replace it, I didn't know if I had to replace the whole harness or how that works... I'm going to call the local dealer and see if they have any input also...Thanks guys...

can you use a long tie- rap or tie down and run it around the computer to pull the male plug tighter into the female plug?is that the pin that was bent? find out which one it is for sure and you can push the wire on through the plug and put a new end on it and then put it back in place. it dont give you much room to work with. hope thats what it is, in which case the diagram really helped. you did good.

Couldn't have done it without your help though, and yes thos diagrams helped more than I could have imagined...
As far as options, I talked to a dealer here and they may or may not offer a replacement clip... Some help they are... I'm not sure which pin it is, it's hard to tell, I do know that the pin that was bent was on the computer and not the "female" clip... I'm almost positive it's in the clip from the harness and not the computer clip because when it didn't start the last time, I put the new computer in to try it and it still didn't start. I assume that it's the harness for that reason. I have no idea once so ever on which pin it is though... I will try to tie or strap it down and see if that takes care of it. I'm going to call out to the dealer again and see about that clip. They need my ID number and such that i don't have here at work... As always, thanks for the help and I will let you know what happens in the next few days...
