Question about 1989 Jeep Cherokee

1 Answer

1989 Jeep Cherokee w/ Fuel Injected 4.0L

I replaced the ignition coil and that solved the bucking and stalling problem. However, even with the new fuel pump, new fuel filter, and new ignition coil, I'm still having problems. I still get a hesitation when accelerating and when the engine is at normal operating temps it does not want to refire. Could the problem be the pressure regulator or somewhere else?

If the Jeep is stalling when hot and hard to restart, replace the crankshaft sensor.

after replacing your ignition coil, try replacing also your high tension wires.

if this does not solve your problem, try using another battery (preferably a larger one), might as well be a weak battery

My jeep will stall when I start it up then once it warms up it will go away. After the truck is driven a while the shaking and stalling continues. What can it be? I have replace the spark plugs 3 weeks...


You will need a multipoint check on the engine.
start with the fuel, fuel filter, fuel pump, fuel injectors and the fuel lines. Fuel problems are heat dependant and wil show up in cold or warm condition. check calibration of pump.
Now check the ignition circuit of the engine. start with the plugs- now being new- check the HT wires, the HT coils, the triggers to the coils- the ignition system.
Also check the fault condition of the ECU.

Check voltage at coil. Check coil output (spark should be healthy even at 1/4" away from ground). If OK, then change module The only testing on module is with a special tool. Therefore if contacts are clean, that's all you can do with it!
