99 4.7l No start...Please Help...
Replaced the engine in my 99 Grand Cherokee Limited 4.7l, first start, engine started up no problem. Drove around town all day, on my way home. Truck shut off, all gauges went down, sentry light and check gauges light is on.
Towed it home, tried disconnection battery for so long, still nothing. Pulled all the wires off the pcm, and what not, cleaned them with electrical connection cleaner. After doing this and messing ariound with just about everything it decided to run all of a sudden. Parked it, went out an hour later and tried to start. Nothing...
Cranks no problem, sentry light is on(not blinking), check gauges light is on, low fuel gauge is on(1/4 tank), gauges all down, battery has good charge. All windows and lights work. Over head display works. No CEL.
Just yesterday I replace the crankshaft positioning sensor, pulled the connection off the tcm, messed with everything under the dash. Started up. Moved it 20 feet and let it run to charge battery a bit. Turned off, and on no problem 20 or so times. Thuis morning, No start...
Now i am led to believe that maybe the pcm or something is shorting out. Any ideas guys and gals. I really need to get this fixed.
