good evening my name is ***** ***** I will assist
did you use new or used pcm?? why did you replace it?? did you have it flashed to your car???
did you check for spark or fuel???
when you turn the key on, does the check engine light come on??
if you cannot connect to the pcm and no check engine light, then there is something wrong with the pcm.
did you communicate with the old pcm????
did the light come on with the key on????
ok, then there is something wrong with the new pcm.
I would put back the old pcm and see if you can communicate/ if not check all fuses with a test light for power.
was this a new or used pcm
good, then it was bench flashed by the dealer. it sounds like you have a power issue to the pcm. check all powers.
check the tps sensor for a 5 volt reference voltage. that will tell us if the pcm is working
ok, the pcm is working if it is sending out a reference voltage.
have you gone over all the wiring harness routing and connections???
is the distributor new or re built???
is there power at the coil??
the coil should have a positive and negative terminal. you need to have 12 volts on the positive side. the negative side should pulse while cranking.
do you have a tach?? if you do, does it move while cranking???
you have a new crank sensor as you said. check the connector.
jumps the volts???? is it 12 volts???
9 volts is cranking voltage.does the negative side pulsate the voltage. you can better test that with a test light
