SOURCE: 99 GMC Sierra Pickup: Crank but no start. starts

The theft light issue is a good observation. Have you replaced the key tumbler or an ignition component lately? Has there been a lightning storm close very recently?

What the flashing security light is indicating is an attempt to relearn the key you are using.
Turn the key to run position, allow light to flash for 10 minutes, when light stops flashing turn ignition to OFF position for 5 seconds, turn ignition to run position and start over. Do this for 3 consecutive cycles, the the theft system will relearn the key cylinder code and store it once again.
Try that first before you go any further.
Let me know what you find.
Regards,

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.

My jimmy just died at a drive thru we have changed the ignition module then the crank shaft censor then the computer still not working the engine will turn over but not catch..what do i do now????


what gave you the reason to change all the things you have replaced. and just remember just because you replaced something doesnt mean that the part may not be defective... check for fuel, fuel pressure, spark, compression first. then i can help you.

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 gmc jimmy wont start fuel pump comes on and cuts off but will not start.I have changed the fuel filter and that did not work. Is the pump not building the pressure it needs to start or would my...


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.

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.

Fuel System on 1998 GMC Jimmy 4.6L engine


That's right! Fuel pump is in the fuel tank, some car has opening to acces in the trunk under the carpet, some car you need to take down the tank, my advise is get your self a service manual for your truck its about $25.00 and it will help a lot.
Good luck.
