When starting the GMC 1994 S-15 Jimmy it cranks but does not start. after awile it stars and runs. when it rund there is no miss and no hesitation. let it set overnight and it has the same problem again
The pressure relief valve is in the spider fuel injector not the fuel pump. We have had our 94 gmc jimmy for 4 years & have had to replace the fuel injector 4 times which cost right at $500 each time for the part. Yes the spider fuel injector cost averages around $500.
This kind of problem is most often caused by a failed check valve in the electric fuel pump, the lines and filter drain after setting and cause very long start/crank times, the check valve is part of the fuel pump in the gas tank.

we are having the same problem till the fuel pump went out of it a few days ago.
The noise dampener was leaking back through it. The part costs about $80.00. I put a piece of fuel line hose on it and it workd fine
I have a 94 jimmy where it has a hard time starting after it has gotten cold also. i thought it might be the battery so i replaced it but it still doesnt start. Itll turn over but not catch but itll start when someone jumps it off. do you think it's the fuel valve or injector?
vehicle cranks up but will not stay on but for about 1 to 2 seconds. It only stars when you put starting fluid in the TBI mouth.
