Question about 1996 GMC Jimmy
The wire harness to the fuel pump sending unit may be going bad which is common to happen. The harness is around $15.00 and it runs from the frame to the top of the gas tank. The other thing to is the fuel pump sending unit may be going bad and the float in side that measures the amount of gas, has gone bad and the unit may need to be replaced. As for the rough idle, it cold be related to the fuel pump starting to go bad and the fuel pressure is just marginal to keeping the engine running. The fuel pressure during cold start should be 62-65 PSI and should drop about 5 PSI when the engine is running. The other thing to that would casue a rough idle, would be time for a tune up, "spark plugs, wires and distributor cap and rotor, fuel filter"
