ok, let it set for a couple of days, went out and fired right up. Took it down the road a couple times taking it easy and it ran fine. Turned on the AC and cruised a little, ran fine. Left the ac on and flogged it a little, with peddle to the floor and downshift. Didn't miss a beat. When I first...

Ok, rather than start a new thread and try to explain everything that has been done to the truck, this thread has it all, but I have a new problem. Was merging on the highway, semi beside me so I went to accelerate, the truck downshifted and backfired. Let of the gas and it ran fine. A few days...

FIXED! The 02 sensor issue wasn't it. I had changed everything on the fuel side and most everything on the spark side, and was still having troubles. Come to find out the new ICM was bad, but that only partially fixed it. I went to a local garage, spoke to the owner and he rattled off several...

Yeah, I've heard nightmares about those, and it's an expensive part. I think those are '94 or '95 and up for the v6 and '96 for the v8. My '92 is just a simple spring FPR and 2 injectors shooting into a hole for each bank. Basically a carb with 2 injectors instead of floats and bowls. Much more...

I think I got it. Just went and scraped all the skin off of my arm to unplug the 02 sensor. Who decided to put the plug up behind the trans!?!? Engine was cold and fired right up, which it normally does when cold. It instantly started flashing the CE light. I didn't think it would do that until...

A few of them were wet when I changed them out yesterday. That's what is confusing me and let me to think of bad spark. Dumping fuel, bad spark, finally sparking with a lot of fuel, but if the 02 sensor is showing rich it should be pulling fuel. I wouldn't think that is an issue at starting...

No disintegrations, I think you may be right, I don't think its the water causing the odd starting issue. The truck finally threw a code. The code was a 45 o2 rich. Correct me if I am wrong, but if it is reading rich, it will pull fuel and cause it to run like a bad fuel pump. I wouldn't think...

Hi John, I saw your reply and thought, "that name sounds familiar!" I'm pretty sure we did meet at towers. I'm not in Lauderdale anymore. I moved to Fort Wayne IN about 3 years ago. I miss it and will probably move back in the near future. I don't think there is a pressure port. I'll double...

Thanks for the input guys. I've been racking my brain with this one. Everything seems to be in good working order, so I said to myself, what has changed? I don't know if I am right, but this is the path I'm going to attempt today. The problem with this truck is that it was a salvage title in...

92 GMC Sonoma 4.3 tbi Ok guys, some may remember a few months back me doing several things to get it to run right, ended up being a fairly new fuel pump had gone bad. Here I am several months later and it acted up again. Changed out the fuel pump and filter. I cleaned out the throttle body and...

SOLVED!!! After a week of chasing my tail, messing with the wiring on the remote start, doing reset after reset, cutting the yellow wire while running, doing the resistor bypass, and lots of deep thought, I went back to the basics. I knew the signal was not getting to the computer. A relearn...

If the key sends the wrong signal to the computer, it cuts power to the injectors, and sets off the security light. Leave key on for 10 minutes, and that reprograms the computer. I do that security light goes off, but still doesn't give power to injectors unless started with the remote.

Shifter is fine. I will take a look at the purple wire. This should have been a 1 hour fix and I've spent 3 days on it now and it's still not working. Now if I start it with the remote and apply the brakes it kills the car and unlocks the doors!!! The car was running fine until the cylinder lock...

It starts fine with the aftermarket remote start, but not with the keys, then put keys in, turn to on and it will work fine sometimes. Other times it dies when you put your foot on the brake to put it in gear. It started with the keys a couple of times then stopped working.

I switched out a new ignition cylinder, had to drill out the retaining pin. Went through the whole theftlock relearn process for the new ignition, got rid of the security light, but still won't start with the keys. :mad:

another odd thing is, the way the car sits now (in park) the steering wheel will turn lock to lock. the steering wheel will not lock. it has a remote start and will start and run, but still cant turn the key and put the car in gear.

I want to thank buick mike for helping with my last plea for help! Here is another for my buick brethren. Ok guys, been all over the net. This happened to my girlfriend's daughter's car. It seems these switches are notorious for failing, but mainly for the "theft lock" failing. Also the key's...

Pulled the old pump, put in a new cheap (lifetime warranty) pump in 15 minutes, and now she runs perfect. My first thought was fuel, but I assumed the pump was good. Shouldn't have assumed! Thanks again guys!

Mike, u may have called it. I basically had eliminated everything but the ecm, but assumed my 3 year old pump was still good. At best it's putting out 8 psi and when power breaking it dropped down to 4 psi and started to bog. Thanks!

Thanks Mike. I checked it when I put the new pump in a couple of years ago. It was a solid 12 psi. I went to the local Napa this morning, but they don't rent tools, it seems to put the fuel out when not in gear. Guess I'll drive the 12 miles to the local AutoZone. :mad: I cut a hole in the bed...
