1999 Jeep Cherokee V8 Automatic 130, 00 miles
Cranks, no spark.
I just finished getting the aluminum heads rebuilt and replaced the head gaskets on my jeep. The heads were pretty warped but repairable. I made sure to mark EVERYTHING while tearing the engine down to the block and marking every wire with tape and a description of where it goes. When I removed the timing chains from the cam shafts I made sure the crankshaft was at TDC and the V8 marks on the camshafts were straight up. I did notice (with my OCD nature) that the V8 marks weren't perfectly vertical, they were about a tooth to the right (left if sitting in the drivers seat).
Now I have everything back together but no spark. I took a coil pack off and tried the screwdriver test, no spark. I used a known good spark plug and inserted it into the coil pack and still no spark.
Is it possible that the cam position sensor just happend to go out at the same time that I replaced the head gaskets? Is it possible that the shop that did the head work may have magnitized the camshaft's tone ring? Where should I go from here? Do I need to tear it down to the timing chains again? Is there a way to make sure thats the problem before I pull it all apart again?
One more thing. While it was disabled in my driveway, someone broke into it and stole the aftermarket stereo. I don't believe it had an aftermarket alarm in it but could that also be my problem? Since the thieves just cut the wires to the deck.
have the same problem?
