you may have a bad connection at either crank connector(circuit 630, 639) or the PCM ground connection at C1/ circuit 551

639 is the power feed to both crank sensors

630 -C10 pcm cam signal.

I would check and pinch the connectors to make sure they are tight


good luck

thanks for the reply! I will check this out tomorrow and let you know!! Thanks again!!
you are welcome
