The fuel pump is getting weak. The vehicle requires a specific amount of fuel pressure to run properly and the pump has gotten weak enough that it's not suppling the required pressure. Very common problem with your kind of vehicle.

chevy and gmc trucks have an on going problem with this,turn the key on,and get a rubber mallot or a hammer and hit the bottom of the fuel tank a couple of times,this will unstick something in the fuel pump/sending unit.

I have a 1998 GMC Jimmy. Cranks, but won`t start. Fuel is full. Engine stopped while driving. Battery light came on. Any suggestions?


the battery indicator light usually comes on after a lose of power. Sounds to me like either bad gas, clogged fuel filter or a bad fuel pump. Easiest way to check this is have someone turn the key while you stand at rear side of vehicle and listen for the whinning noise a functioning fuel pump makes as it pressurizes the system.

P.S you dont have to start vehicle to check pump. only requires turning the key to the on position. Good Luck

2000 jimmy will crank but wont start, fuel put is


Then it is the fuel pump. Can you hear the fuel pump come on if not that is what it is. That is why when you put fuel in the intake it started. Good Luck.

1997 , wont crank


if starter will engage and engine can turn over quickly it should start.

however.. i dont know how you are verifying it has fuel as its a high-pressure FI system.

these systems by GM are VERY finicky and unless within spec precisely it will NOT run. i suspect fuel pump is putting out less than 57# which is min for these.

fuel pump known failure part. if replaced you MUST also replace wire harness at tank as they usually fail internally w/melted wires you cant see through wire sheath. low voltage will KILL the new pump.

also you didnt note engine size and family...

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.

My 98 Jimmy runs on synthetic oil and starts well after sitting in cold weather. If the weather is the problem, try checking that. If it is warm... sorry no ideas.

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.
