Check the wiring going to the coil. If you installed an alarm on that vehicle disconnect the main power wire to the alarm to disable the ignition kill circuit. Locate the ignition relay located on the drivers side fender wall or in the power distribution box under the hood and test it. finally, there is a fuse on the interior fuse panel that will give you this condition. I do not have the exact location so check all fuses in the panel and replace any blown fuses.

    Also, pull that distributor and crank the motor over while you are watching the rotor. If the rotor does not turn then the Distributor shaft or timing chain has broken.

No power on hotwire going to distributor? Or just no spark still? If you have done all that and still have no spark I would definitely look at your ignition module should be inside the distributor if its just your hot wire that is easy just run another one from the ignition panel in your fuse box.

I have a 1992 jeep cherokee 4.0 inline 6. i am having the same starting problem as everyone else. while driveing it shut off i got it started 15 mins later it did this til i got home. ever since it hasnt...

Try unplugging the ECU wire harness from the ECU, clean the terminals and screw it back on tightly. Might be a bad connection at the ECU. Also, I have no idea what 'block sensor' you are talking about and that jeep 4.0 has a crankshaft sensor bolted to the transmission bell housing, not a camshaft sensor, right?

We have a 1991 jeep wrangler 4.0 and we changed the fuel pump and now the coil is getting no fire when i hook the battery back up

My 1991 Wrangler would alternate between no spark and no fuel. After replacing the crank sensor, the coil, and the fuel pump twice I started chasing wires looking for a bad ground. There is a black with a yellow stripe wire that comes out of the rear body harness between the front e brake mount and the front door post(very hard to get at)right above the bottom dash edge that should be securely grounded to the front e brake mount. As soon as I secured that ground everything worked properly again.

I have a 94 jeep wrangler 4.0L and it wont start. I have changed the coil ecu and auto shutdown relay. The coil receives the correct voltage and has a good ground but no spark from the coil. Any ideas?

Two other thing's control the spark, the pick up coil assembly, sit in the distributor or your crankshaft sensor, sit on top of the transmission over by the driver side, held on with a 10mm bolt.
