[QUOTE="Peg Leg, post: 991892, member: 63561"] I think you are right, or a world class coincidence. I know I put the fuse in the slot it came out of (completes red sharpie mark that I put on slot and fuses directly beside it) I know I have fuel. I know I have compression, and I have no spark. Working backward, A low voltage is supplied to the ignition coil by the PCM, the ignition coil step it up and lights the plugs. I Know that the plugs are not hot. I need to know if the ignition coil is hot, And if not is the PCM hot. If PCM is not hot where does the PCM directly get its current PCM fuse is good#44) , dont know if PCM relay #54 is good(How do you verify). I used to have to go out in the field and reseset 50rf relays at substations after they tripped, but these should reset automatically. I guess work backward and see if I run into fuse #30. L1, how would you do it short of hooking up to a $10k DCPU? PL [/QUOTE]
