Where is the ECM located?


ECM is probably OK. On this year its one of 3 things. First its the ignition coil causing the problem. This is the most likely cause. Second would be the fuel pump is going bad and partially locked up. The third reason is the crank sensor is going bad. Jeep ECMs don't usually act like this, they just stop working and don't act up intermittently. Not saying it couldn't be faulty, just unlikely.

It keeps shuting down i have replaced fuel pump, plugs,coil, when driving it will just shut down if let it set for a few min it will start back up now it will not start...


You need to figure out which one you are losing. You are either losing fuel, or spark. When the engine quits, immediately open the hood, and check for spark. Let us know what you find. Good luck!

93 jeep cherokee 4.0 dies when stopping but idle till fuel gone


GREAT INFORMATION...

however, you were not clear about fuel pressure

was fuel pressure OK before and during the concern...30psi and have you check flow

PLUS...during the concern are you loosing SPARK? Coil is great suspect!

while the code for the crank sensor concerns me I'd start with the most common Jeep concern...the ASD (auto shut down realy)

when you start testing again remember to check the CKP output at the sensor and the CKP input at the computer...you might have a CKP circuit that is worn out

After I drive my jeep some, if it is somewhat warm or not cold weather, my jeep has a hard time starting. It may crank but run a little ways and cut off going down the road.I have had the coil, plugs, plug...


if it shuts off after running for a while and will not restart for about 10 min,a bad crank sensor will cause this. abad crank sensor will make car shut off and not restart for about 10 min. put a scanner on to make sure. a check engine light does not allways come on. if you do not have a scanner, any auto parts store will scan it for free.

I've got an 86 jeep cherokee with a 2.8l with CA


Sounds like the cat. converter is stopped up. Also when the power piston dosen't work it will cause a hesitation when you first hit the gas. But then it should pick back up and accelerate normally.

My 95 yj hard too start after i change my fuel


when it does not start you need to verify no fuel pressure, Most likely your problem is the wiring harness is bad which will destroy a new pump if the pump is not geting the voltage required.

Starts well,runs wellfor five mins but then cuts


My first guess would be the fuel filter. It is probably almost completely plugged.

You might want to replace the crank sensor on the bell housing.
