My truck will start fine when it's cold outside or it has sat for a while, but if go to the store then come back out, it usually gives me trouble starting. Sometimes it will just keep turning over for a few seconds and take right off, but sometimes I will start it, it will turn over for a couple seconds, completely shut off like the battery has been disconnected, then immediately come back on and start right up. My battery terminals are loose and I have to tighten them periodically. I just needed to know if that was the key problem or if it could have anything to do with the starter or anything else.

o I was just about to go to bed but I saw this one. I'm sure you've tried everything possible to fix it. Our sonoma did the exact same thing. The fuel pump is going out most likely.
The reason that it will start when its cold is because it hasn't had time for the pump to get hot. Check this out the next time your running low on gas. Does it seem like it breaks down more often when your fuel tank is almost empty? If we kept the fuel tank full the truck didn't break down as often. I'm not totally sure if the pressure in the tank improved the power and made the pump work less or if the added gas insulated the pump so that it didn't heat up as fast, but it worked.
It did this for some time. I thought that when a pump went out, it just stopped working. The ones in the sonoma will drag on, trying to keep working forever.
When we took it to the chevy dealer they told us that the sonoma's were having a lot of fuel pump problems. Also there is this thing I just got in the mail about a month ago. It had to do with the tailgate wire hinge thinge. The things that support the tailgate when you open it . I guess they are having trouble with the wires breaking down over time and if a person sits on the tailgate it breaks and the gate and person fall. Ours didn't have this problem, but I thought I would mention it.
I just went and traded our sonoma for a new trailblazer. I love it so much! lots more room!
hope this helps!

ok if all the simple things that i name off check out then u have one problem first i want u tighten all battery cables again use the proper wrenchs side post battery on gm is a 5/16 wrench then follow the cables to the alternator make sure the charge wire is tight and make sure the alternator is secure to the engine as it is grounded through the engine block then check all cables on the starter even the exciter wire on the solenoid then check the starter bolts for proper torque as it grounds itself through the engine block as well. then if all that checks out the problem is ur ignition switch in the steering column breaking contact. common gm problem with the blazers s-10 and sonomas and jimmys on 96-2000's just replace the ignition switch and its the harness not the lock cylinder REMEMBER NOT the lock cylinder but the harness. hope this helps

Sounds to me such as you have a bad IPC; restore at a GMC broking is around $450.00+tax. The Tech, nicely i'm unsure in the event that they could test this previous of a motor vehicle, yet while they could test the gauges, they could be waiting to allow you know for effective. you like a Diagnostic device examine - device Cluster for starters. additionally, seems which you are going to have some type of leak on the exhaust inflicting the smell...once you assert you had the cluster checked?"Who checked it?" no remember if it incredibly is not any longer a cluster situation, you have lots of of problems. The wipers seem to have a bad module. Oh my gosh, i ought to circulate on and on with this one. am i able to activity you in a Low charge on a Small new vehicle? I even have been a GMC service consultant for type of 9 years, and it seems such as you have hundreds, if no longer hundreds of greenbacks well worth of upkeep right here. Sorry, I don’t propose to hose down your hopes; Oh yea, i'm at abode, and dont have the code exams right here, yet i think of a P0443 is a vapor code, could be a bad gas cap? Chris ok.

Well I would say that one of the sensors is giving false information to the computer. I would have a "Scan Tool" type tool to see if or which sensors are out of limits. Although a loose battery terminal could cause a similar problem of an intermittent stalling. The point is it could be any number of things.

Try replacing the big black ground wire that connects to the battery, putting some dielectric grease on the connections. If that doesn't help, replace the big red positive wire. If that doesn't do it, it'll have to be put on a diagnostic machine to pinpoint the problem, although using a code reader might show what's wrong.

If your terminals are coming loose, you're not tightening them correctly. They're making lousy contact when they get hot. You might need new cables if the clamps are all the way closed.

Probably a choke issue, it's not completely warmed up and the sensor thinks the engine is warm and doesn't give it extra fuel at startup.
