Question about 1990 Jeep Cherokee Limited

1 Answer

1990 jeep cherokee laredo 4.0 liter 4x4

Engine will start and idle for a split second and then die-if i force the ignition-"holding it in the on position it will idle". i have checked all hoses and wiring and all basic fuses and the wiring on the ignition assembly. i have replaced the crankshaft positioning sensor-the fuel filter-and the idle air control valve or stepper motor. alternator and battery seem to be ok too!
i was wondering if it could be one of the fuses or sensors in the engine area? and how can they be tested without the diagnostic machine? or is this my last resort? thnx

the first grand cherokee laredo was in 1992 . it was all jeep sports back then, the blocks are all the same .you will need to use some of the sensors from the old motor, the distributor and oil sending unit and temp sensor. will be no problem. if I can put a ford ranger motor in a mercury sable your swap is easier

I have a '97 Jeep Grand Cherokee Laredo 4.0 liter that won't idle


Check your throtle postition sensor. It monitors what postion the throtle is at and sends that info to the ecm. It will go bad and cause that problem.
