Under the hood on the top of the engine u will find the metal fuel supply rail, on that rail there is a metal valve it looks just like a tire valve, u check the fuel there with a test guage that screws on there at that port, the test guage is cheap and avail at any good parts store.

98 jimmy starts... but then dies and will not start back up untill later,changed fuel filter


Have you checked your fuel pressure. You may have a bad fuel pump. If you have good fuel pressure take a good look at your cap and rotor. 4.3 liters have a notorious cap and rotor problem along with a coil wire issue. The coil wire can rub on the firewall or other places and cause you problems. I would start with checking your fuel pressure with a fuel pressure gauge.

Will turn over but not start-need help quick


One easy thing is to tap on the bottom of the fuel tank while trying to start it.If it starts then you know it`s the fuel pump.The only other thing is to check the fuel pressure but you need a pressure tester.The other thing is to check and make sure you have power to the pump.This is the gray wire at the pump connector.Also make sure your ground is good.The specified pressure is 55-60 psi.Hope this helps.Good luck.

Hard start when cold/first start in morning


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.
