2006 Jeep Liberty 3.7 NO start
PCM is not bad ever, (99.999% good ,ok)
never replace most expensive parts on any car first that be over the top. OK?
learn to test not GUE$$
you love to throw parts, why?
fuel will be dead, injectors dead if the PCM brains see spark dead. this is hard pure logic, and by law too. no crash and burn.
the spark is dead will it is dead for only these reasons on DIS spark engined cars, DIS has 4 COPS (coil over plugs.)
you said Spark dead but did not say all 4 COPS are dead;
oops that matters huge but lets pretend you said 4 cops dead.
if you'd have scanned the PCM you'd have see P03xx errors but did not do that, so you work blind.
cmp dead'
CMP dead
and now learn this secret, if he PCM sees 2 good CMP and CMK
not in timed right it cuts spark dead.
modern cars now DO THAT to stop valve damage.
and engine can be and interference engine, on all DOHC engines or orthers too.
So you timed it all wrong. that is my answer. blind and hands free.
me..
my Jeep show CMP/CKP Incongruity errors timed wrong
and I love that, as in saves its own bacon the best it can;..
next time , stop and ask here, and not throw parts.
forget fuel fix spark
scan it: here is how to scan properly for spark.
tool connected (obd2, 16PIN PORT AT KNEES)
scan it key on ,OMG it shorted errors P03xx?
then you crank it for 10secondS no more. battery fully charged !!!
and release the key do not Turn off the key noW !
scan it for 5 full minuteS to see if the P03xx errors roll out now
it will .i bet.
if the PCM cuts spark , it for sure knows that and tells you why now.
sure bad relays sure, and fuses sure.
The ASD relay cuts out by PCM demand and for errors it sees.
