ok, replaced cam sensor, the part store wanted to call it something else, but still wont get spark, so not sure where else it is. crank sensor is still good, but im getting a code 11 still.tnt in the gas tank is soooo tempting now....
OK both OP and I have been crunching on this. The only suspect issue is using a test light on cranking and checking for juice to distributor we get no flashing light. The only issue is spark. I am not sure if the 96 Grand Cherokee is supposed to work with an OBDII reader but this one will not read codes without using the key on/ off method. When I checked the Crank Sensor it showed 000 for resistance. We will pull it and recheck while it is out too. I used my multi meter and found the 5 volts everywhere fine. Again the only problem is power to distributor.
When key is turned on we get 12v to coil for 1 second then the relays all click and out goes the 12v. While cranking still no 12v. I have tested all the relays and swapped sever times for giggles. No chnage. All fuses are good and show 12 v both sides with key on. I have read and tried all the sticky notes for common causes. Next trip to the jeep I will retest with the new PCM. Per my kid nothing changed.
Motor turns over well. RPM while cranking is good. Battery contacts are clean and fuses are clean. All relays tested good. THe only issue I can find is no spark due to no 12v to coil.
Where would the security box be on a 96 and is there a test for the box as well?
35 yrs turning wrenches and this is a bit annoying.
