1999 JGC won't start
1999 Jeep Grand Cherokee Laredo 4.7 V8 won't start. I bought it not running. Last owner stated it died on the freeway, acted like it wasn't getting fuel. No codes
Got it home and put starter fliud in it, it started and backfired through intake. And the top of the airbox flew 50 feet, and the starter fluid caught fire.
It never started again after that.
Then I got code P0320. Changed both Camshaft and Crankshaft sensors. The Crankshaft position sensor was broken and part of it is in the oil pan. But Still won't start, no luck. No codes.
I replaced the battery because it was dead and had a crack in it.
Replaced the spark plugs because they were completely shot.
I have no spark. I believe that its getting fuel but wouldn't rule it out.
Another issue not related is the doors won't lock with door driver door locks.
Any help appreciated.

Old fart with a wrench
It's possible the timing chains are out of whack, or one jumped.
