Last night I back flushed my heater core on my 99xj and I think I got my ignition coil wet.. ran great for about 20 min and while burping it/topping of coolant, it ran rough, sputtered and turned off.

My question is what parts (other than spark plugs) could have shorted/fried in this *@%+ing predicament:
ignition coil, ASD relay - camshaft position sensor?

I won't have testers for any until later today when I can get a ride - just trying to brainstorm some possible solutions in the meantime. Any help is greatly appreciated!

 

Walk (LOL) to the auto parts store and get several cans of CRC QD Electronic Cleaner. Spray all unplugged connectors (CMP/Coil, etc.), remove the distributor cap and CMP and spray them down. Spray the coil down.

 

Haha yea that's my next step... or couple thousand to the napa about 1.5 miles away.

Do you think I could have fried the fuse? Should I just replace the coil for *****?

 

You could check the mini fuses in the PDC.

Don't replace the coil. It's pretty much sealed up, but you may want to look it over closely for craks in the sealant.

Edit: Here's your PDC fuse layout:

 

CMP?

 

Nevermind. Thanks!

 

2 mini fuses aren't showing they are working in my PDC - the fuel injectors/coils 20amp and the os2 15amp. They aren't broken. What's that about?

 

What do you mean by "aren't showing they are working"? What method are you using to make that determination?

And, what do you mean by "They aren't broken"? If there's any doubt about fuses, replace them.

 

This style tester.




All other fuses lit up except those 2. Same with 2 new ones in their place.

 

I sprayed all said parts down with the CRC electric cleaner, loosened ground cables for ignition coil and sprayed those really well.. no dice.

I really appreciate your input as I'm at a loss for what happened (other than I got my ignition coil wet).
Still waiting on other testers and assistance from a friend.

 

Those fuses you mentioned are powered by the ASD Relay. The ASD Relay would have to be activated inorder to get power to the fuses.

You haven't started your death march to NAPA yet. LOL

Inspect the coil and distributor before you go, incase you need some parts.

Edit: OOPs, you posted before I did.

 

Unless I missed it, I didn't catch what year your XJ is.

However, you may have three large connectors at the transmission dipstick, just below the heater hose connections at the firewall. If you unhooked these hoses and let coolant run down on these connectors they may be contaminated. Two of the connectors deal with transmission stuff and the other, large one, deals with lots of circuits which may have something to do with your issue.

Recommend you check these connectors,.

 

The ASD relay needs the engine running to be activated or do you think that the relay may be shot/fried?

Haha I borrowed my roommates car for like an hour - napa has the ASD relay fuse but the coil won't be there until about 2.

Distributor cap and rotor look fine and dry. However, the coil appears to have a crack on the top..

Mine is a 99 xj sport.

 

Oops, it is 2:30 and I may have to do that death march!

What would I look for to be bad in those connections? Dirty fluid? A clog? A f<*$in elf who has given me horrible luck with my jeep for 3 weeks?!

 

Sorry, I misread your post.. no those connectors did not get any coolant on them
