Please help me, I have an 1989 Jeep Cherokee Pioneer 4.0 l 4wd, auto. The problem I am having is: The engine is turning over, but the darn thing just wont start. After initial tests I found it is not getting spark. I replaced Dist. cap, rotor, wires, plugs. ignition coil (tests revealed it was bad). Then some guy told me it could be the igniton switch so I replaced that and still the same result. Could someone please help me either to fix the problem or do some other diagnostics so I can get this fixed. Your help will be greatly appreciated.

The only thing you can do is slowly trace the system. First of all, get a multimeter and have someone churn the engine. You should have power running to your coil and power coming from the ignition module (check this component first as you didn't replace it according to your post). If so, pull the wire off the coil and see if it arcs. That will seperate your problem from the primary or secondary wiring. Just keep checking where your power is going. Ignition problems arn't usually hard to figure out, they're just tedious. If you give some more detailed info, I could help more.

I had the same problem with my mustang and after replacing the coil and ignition module it turned out to be the pickup coil in the distributor, I don't know if jeeps are so equipped but I think they are, and I feel for you buddy because I have an 87 jeep pioneer 4x4 auto, just like yours it sounds like, and mine won't start right now but I think it's the switch. if there's a pickup coil in the distributor it should be less than 20 bucks and fairly easy to replace. good luck my friend

If an engine turns over but doesn't start, it is most likely either a problem concerning fire or fuel. In some rare cases it is due to lack of compression ( but you would have to have lost multiple valves in order for nothing at all to happen). If you have replaced all of the ignition components then I would recomend taking a look at your fuel delivery system.
