Why do I have no spark from the distributor to the spark plugs? How do I check it?

 

I have replaced everything from the coil, plugs, plug wires, camshaft sensor, crankshaft position sensor, rotor, and distributor cap.

 

Jeep Cherokee? What year?

Have you checked the ASD fuse and relay in the PDC (power distribution center, under the hood passenger side). If those two items check out, but no power is detected on them when ignition is in the on/start position...then start checking the ignition switch itself and make sure the connector/wires are not heat damaged.

 

I did replace the ignition switch too. I get it to crank just not spark. I will check the fuses again.

 

replaced the fuse and relay. Nothing still.

 

It is a 95

 

Man, you're firing the parts cannon alot.

 

Haha, I would have replaced it all anyway. I just can't figure out why no spark at all.

 

You replaced them. But did you test for voltage on both sides of the fuse to ensure it is powered up as it should be?
