Question about 1998 GMC Jimmy
How do i check the fuel pressure on my 98 gmc jimmy. i want to see if my electric fuel pump has failed
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.
