1993 jeep grand cherokee will not start

Jeep will not start, gets fire to coil, but when cranked does not. Any ideas? We have tried changing coil, crank sensor, new computer, distributor, and checked all relays and fuses. Still will not start. Jeep ran great before we changed transmission. We crushed crank sensor on bell housing and now will not start.

    had the same problem with my 5.2,it was the 2-wire temp sensor under the back of the air conditioner pump,pull on the wire and see if it is corroded off.

You may have bent the flex plate ring.so it might be to far away from the crank sensor air gap.

I have a grand cherokee 1993 it wont im not getting fire


Might be your crank sensor, your coil, your distributor or even your ecu. All of those being bad will prevent the jeep from firing. If you do not have a check engine light lighting up on the dash when you turn the key to on, before trying to crank the engine, then it's your ecu which is bad and needs repair.

Jeeps have a part called the crank sensor, when working properly it senses the electrical feild produced by flywheel. This crank sensor which is located on top of the tranny bell housing has been known to go bad. When this crank sensor goes bad the CPU does not get a crank reference and the computer will not fire the injectors. This crank sensor will fail under high temps and if it is old will fail also when cold.
You have to find out if the injectors are getting a pulse when the car does'nt start.

1993 JEEP GRAND CHEROKEE LAREDO IM TOTALLY BAFFLED


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)

1993 Jeep Grand Cherokee won't start.


The crank and cam sensor's are very common problems on these jeeps. Check them or have someone check them with a scanner. one or both are most likley the problem.
