Question about Jeep Cars & Trucks
02 jeep, no model stated but seems to be grand Cherokee.
answering for USA cars only not exports, etc.\
GC is WJ jeeps, real name. WJ.02
I can see you didnt scan it first.
crank for 5 seconds and see if the scan tool tells you why it cut spark 99% of time it will
ours has 8 cop coils, 8 coils over plugs.
if all 8 are dead.
1: CKP or CMP sensors dead.
2: the PCM on this car , can cut spark if P0016
code for cam out of time.
they do that so you dont bend the head valves. over.
since you skipped the most important step, SCAN IT.
i cant work to the end, or solve this.
if you have spark for 3 seconds, and it dies after
that is the ASD dropping out, and is PCM command to do that, and the scans tell you why, there are 1 to 8
reasons why, (codes DTC) stored,
make sure the PCM IOD, fuse is not missing or bad
this is the PCM memory fuse, keep it working.
or data can not store.
