01 jeep 4.0 no start

Asked by Sep 27, 2016 at 01:12 AM about the 2001 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

I have a 01 Jeep Grand Cherokee the head gasket
was bad but still ran, I drove into garage and
replaced the gasket and during the work the coil
pack fell from the car and broke, after getting a new
pack and all the work was done jeep won't start. I
checked all valves and torqued them to 22 ft lbs. I
have good spark and the spark plugs are wet with
fuel, my compression is around 140 across the 6
cylinders. When cranking I can hear it backfiring
through the intake. My question is how could the
timing be off? I didn't touch the timing chain and
the spark timing is controlled by ecm? Also I tried a
new crank and cam sensor with no change.

May have timing off sounds like a possibility with the backfiring, I would double check the firing order.

No distributor it has a rail with coils controlled by ecu and crank position sensor
