2001 GMC Jimmy 6 cyl Two Wheel Drive Automatic
engine turns over will fire like the timing off. If I continue keep the starter turning it will start run rough and smooth out quickly. Items replaced, plugs, wires, cap & rotor, coil, ignition module, fuel pump, crank sensor and TPS. Also after the engine is hot it takes more cranking time befor the engine fires. It only does the rough start when the engine is cold. After replacing the TPS it has only done this one time in 4 weeks after it had sat for 2 days.
have the same problem?
