1993 jeep grand cherokee will not start

Have your ignition module checked. Also check codes for bad reference signal for cam or crank sensor.

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.

I had the same problem and it ended up being a bad coil pack.

I would try the crank shaft sensor it sends the signal for the fuel pump and distributor.

Crank position sensor mosly likey. Seems like you wasted a lot of money on unnessary parts. Crank sensor should cost about $40

Check spark at plugs. If no spark consider coil.

If the crank sensor (reaR at bellhousing) is dirty, will not start, clean up and visually inspect

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.

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)

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.
