01 coupe f23 5 speed manual I parked the car and returned to it an hour later, to discover a no start issue. Cranks healthy, but no start. I began the diagnostic procedure first with all fuses, nothing found wrong. Checked a plug wire and found that there was no spark. Did not check for fuel at this time. Put a complete distributor on, with crank pos. censor, coil, the hole thing... no change. Put in a new main relay... no change. Put a different ecu, with matching part numbers in... no change. Ran threw all the fuses again with a test light on both sides, all are good. I then cleaned all engine bay grounds, and reinstalled them. Checked several ground pins at ecu plugs and they were good. I have not been able to find a pin out for the main relay, but tested the connector and had good ground, one constant pin, one pin get 12v with key on, and one pin get 12v when I crank it. If anyone has a pin out for the main relay, I think it would be helpful, but I’m not sure I’m even looking in the correct spot, as I have not pinpointed any problem as of yet. When you turn the key to the ON position there is no cel, no green key light, and when you lock the doors, the little red “security” light does not flash on the door panel like it did before. The cel works(I checked) but won’t come on. Everything is stock, and there was no new work done, no symptoms leading up to this, and nothing new or different happened, it just quit... any help or insight would be much appreciated as this is my only car and I’m in desperate need to get it running.
