It would seem that you have a gas leak, or it is not being properly combusted. If the odor is strongest around the exhaust pipe I would suspect that unburned gas is being pumped through, otherwise I would suspect a leak. As you just replaced the pump, that would also support a leak theory. Seems like the best thing to do would be take it to a shop and let an experienced mechanic look at it.

1996 GMC Jimmy have to give it gas to start?


First check fuel pressure and see if is to spec, some times the new pump is to much or not enough. Just double check they gave you the right part. make sure you hook every thing like it was so back track your work. Make sure your filter is on right seens you smell gas and all lines are right on

K1998 gmc jimmy 4 wheel drive truck cranks but wontstart.is getting fire,when it did run it smelled like gas strong


GMC Jimmy's have a record of corroded fuel lines at the fuel pump in the fuel tank. Cycle your key from "Off" to "Run" a couple times then look under the vehicle in the fuel tank area to see if there is gas dripping.

96 GMC Jimmy starts okay but dies after about 10 minutes. It will start again after sitting for awhile, then dies again. Have changed the fuel filter and pump...any other ideas?


If you have replaced the fuel pump and filter I would still check the pump pressure when it wants to die. Check for any trouble codes in the system also.

1996 GMC Jimmy Need help trouble shooting. Turns over but won't


Fuel pump or injector assembly. Need to know what the fuel pressure is before throwing a part at it. By what you are saying I'm leaning tword the fuel pump. Make sure the wires at the top of the sending unit are not burn. There is a small 4 wire connector on the inside of the sending unit. If it's burnt you will need to replace both the pump and sending unit.

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.
