is there another pcm port to read codes besides the one under steering wheel
But when you say pcm port, that's not where you plug scanner in to retrieve codes. You use the OBD port, a completely different port. Is that what you meant? PCM is Power Control Module
No, that would be it. The OBD port under the steering wheel, this is not your car but is very similar
Actually Powertrain Control Module ...and one time I tried to scan a car and thought the same thing, no power to OBD port but the batteries in my scanner were dead

was driving on hyway car lost acceleration sounded like a backfire but not threw exhaust died will not start will turn over got spark after cranking gets a strong fuel smell tryed to read codes no power to obd port
Yikes, That makes me think a timing issue
Check horn fuse, mine was missing. Put one in, obd port has power.
