Hello. I just changed the head gaskets on the '99 3.8L engine in my '95 Mustang. Now it will crank but not start. I drove the car to its present location last week before I tore the engine down.
The details:
1. There is no spark between the ignition coil and the coil end of the spark plug that I tested.
2. My test light shows no power to the positive terminal on the large ignition coil connector. (There IS power to the primary (small) connector.)
3. When I tested the negative terminals on the ignition coil connector while cranking the engine, the test light flashed repeatedly on each one, indicating a pulse signal from the PCM. The light flashed very weakly each time.
4. I also tested the crankshaft position sensor connector. NO POWER to that connector, either.
5. I also tested the camshaft position sensor. It has power.
6. There IS power to the fuse that I *think* governs the ignition coils--slot 18, 20A fuse, in the instrument panel fuse box.
Any ideas? Thanks for reading.
