Jimmy starts but doesn't stay running

Could be a fuel starvation problem. Check the fuel pressure - if it drops below 50 psi, the engine will stop. If that is the case, the fuel regulator is probably faulty or not installed correctly (leaking). Another check would be for an intermittent in the fuel pump connector or a faulty fuse/relay as well.

Will turn over but it wont start

What is the fuel pressure? these trucks need a certain amount of pressure to start, if low just 3psi it will not start, if you are sure the pump is good then you may bad spider injector. check fuel pressure first and also try spraying starting fluid into throttle body and see if truck starts. the pump needs 60 -66 psi to start the truck.

If my GMC Jimmy will not start and my car has a full tank of gas and a good battery what can cause this. My car sounds like it wants to start but just is not able to. Fuel Filter?

Fuel filter, but most likely a worn out fuel pump. The engine needs 62 - 65 PSI to start the engine. Anything less then that, the engine will not start. Start with the simple and check all your fuses and then check the fuel pressure with a fuel pressure gauge connected to the shredder valve.
The valve is located on the fuel line by the distributor drivers side, if the fuel pressure is less then that. Replace the fuel pump and the wire harness from the frame to the fuel sending unit.
Thank you for using fixya and good luck.

2000 GMC Jimmy starts fine, is hesitating/ sputtering to go when I start off from a red light. It seems like when it is about to hit 2RPM.

Check fuel pressure at schrader valve on fuel rail while key on and engine not running. Spec is 55 to 61 PSI. If it is lower than 55 PSI, replace fuel pump and fuel filter.

Will a 1995 Chevy Blazer fuel pump work in a 2000 GMC Jimmy? If not, what years are compatible with a 2000 GMC Jimmy?

That depends on the engine and fuel system. For example, throttle body runs around 12 PSI as where fuel injection (Injectors on each cylinder) can run up to 40 PSI. Run the pump that fits your vehicle!
