For testing, there are some u-tube videos that show each circuit being tested under load. 5v, sensor ground, and sensor signal. need a good meter to check those"hall effect switch" sensors.after trying evrything, THEN buy a pcm and get it flashed with the update. WOT during crank for tests unless u want to disable the fuel pump at the relays for the time of ckp and cam tests

Have you checked the cam sensor. It coincides with the crank sensor to tell it to fire . And it controls the injectors.

    Yes it is a part of the distributor, as I said in the other correspondence, it is a plate under the rotor button, lift it out, and these are attached under neath . They are the parts the wires are attached to.

1993 Jeep Grand Cherokee Laredo 4.0L 6L Auto Trans. Turns over but wont start No spark on plugs, good compression. Just put new ignition coil, rotor cap plugs plug wires. but, checked power supply to coil...


Check for a signal at the ignition coil with a node light or a 12 volt led test light while cranking. Check for a signal at a fuel injector connector jack while cranking. If both these signals are missing. Ignition and fuel signals, then the problem may be some common point. My 've will loose both these signals if there is no crank shaft signal or position sensor. CPS is on rear of engine, on transmission bell housing. Check for connections of PCS.

1996 Jeep Grand Cherokee No Start


I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.

Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)
