90 dohc igniter signal
my 90 dohc protege suddenly stopped firing on #1 and #3 cylinder. The spark from the distibutor and coil is hot, plugs are clean, wires are new, compression on all cylinders is strong, no leak down, changed out igniters and harness, swapped an old (but could have been bad) ecu, changed new ecm, still nothing. Are there any fuses in this system that I can't see? Any other sensor/ short problem areas, Mass control etc. PS. I had had trouble with slipping autotrans that went away with changed trans filter; very susceptible to this, it seems. ptacitus
