It could be the Throttle Position Sensor ( TPS ) or Idle air control motor. Determining this will help be a guide. If it idles but you cannot accelerate, then it could be the Idle air control ( IAC) or the MAF ( mass air control sensor).
If it idles but stalls when you try to accelerate, then I would first suspect the TPS. You could throw a lot of money at this problem and not solve it. I would suggest getting the computer scanned to find out what codes it is throwing before buying any parts to swap.
Hope this helps!!

i think if you checked the sparking plugs and map sensors then check your distributer its maybe not delivering the current nedded to perform the spark to some of the cylinders

2000 gmc jimmy starts in AM fine won't start after sitting in sun all day

Can you jumper the fuel pump and make it start and continue to run ?
Have you checked to see if you are getting spark when it won't start ?
Could be a relay or coil, ignition module, or other component.

2000 GMC Jimmy, starts up every time, but only runs for 10 seconds then dies. Restarts every time but will not stay running. Replaced fuel pump, fuel filter, CAM position sensor, crank position sensor,...

you say fuel pressure is good, but what is it? what is the fuel pressure when it stalls out? Spec is 60-66 psi and it wont run if its 55 psi. the fuel pump relay should be good if the pump runs. Make sure the ground for the pump is good , G402 should be on left frame rail. you may have had it off to replace the pump? maybe? it may be time to stop guessing and have a repair shop diagnose it for you. You sure have replaced a lot of good parts.

My 2000 gmc jimmy seems to have problems shifting initially in the first gear, and lately it has been redlining to 5000 rpm before shifting from 4th gear ( i think). I feel like one day it is just going to...

1-2 shift is delayed and harsh, may not shift into OD: Check Throttle Position Sensor (TPS) for smooth and linear electrical response over the entire range of motion. If not, replace.

This is one of the things i can think of that would cause the issue you gave me. Start with that since it's simple and the other thing to is you can try resetting the ECM.

Turn the ignition key to the run position (engine not running) and pull the ECM fuse out for 30 seconds. Place fuse back in and start the engine, the engine may stall but let it. The ECM is relearning the engine and transmission and then go for a test drive after idling for 1min. The transmission my be running back good as new, if not. Have the TPS checked if not replaced. Good luck and keep me posted.

1991 gmc jimmy over fueling at start up, it wont start unless you push the gas pedal then it runs rough if you let off it stalls. It is getting way to much fuel...

Sounds like the relay is not shutting off fuel pump. Turn the key to on position ( not start ), pump should only run for a few secounds and you will hear a click and pump should shut off, if it keeps running relay is bad. If it works like it should than fuel regulator (if there is one) would be the next posability.

2000 GMC Jimmy won't start

Hi: Have run into same type of problem, turned out to be a dead or very battery. Has nothing to do with the ignitin switch. With a low battery have also had trouble getting the key out of a 95 Jimmy. Boost unit to get running then discommect battery, if unit stall right away replace alternator, if stays running replace battery. If you get the unit runnimg and try to drive it as is you should find lacks power and wants to stall.
