SOURCE: 94 gmc jimmy will not start

You have to determine a few things. Are you getting spark at the plugs? Are you getting fuel to the injectors? You can also read the engine codes to see what codes are stored in there.

SOURCE: i got a 1994 gmc s15 jimmy with the vortec 4.3 it

sounds like it could be a problem in the IAC circuit. The Idle Air Control valve manages how much air gets into the engine while @ idle. It receives commands from the ECM based on inputs from at least the mass air flow, coolant temp, throttle position and oxygen sensors

SOURCE: 95 gmc jimmy rough idle fuel in exhaust drives

Purchase new egr valve gasket with screen on it. The motor as it get older produces more carbon it then begins to break off and when the valve opens it get caught in there. i have cleaned mine several times and finally found the gasket at napa for around 22 bucks. All you need it 10mm wrech and 10mm socket with ext. takes around 10 min to do.

My 2001 jimmy has a slow and sluggish takeoff and acceleration speed. Wiring harness was melted apart from busted heater core hose.would a bad connection cause this problem.


Usually not. If it is shuddering while accelerating it's usually a plug wire. If you have a check engine light on then start there

Why does my 2000 gmc jimmy shut off while in motion?


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!!

What is causing my 1994 gmc jimmy to hessitate on


yep, but more than likely you need to replace your spark plugs and/or injectors.
go to the autowreckers and you can get a new fuel rail with used injectors or you can buy refurbished ones at napa or autozone that are cheaper than buying all new ones.
