I was ten miles outside of Reno and not quite to Truckee doing 70 mph when the engine died. Not a sputter- it was like flipping a switch. Pulled over, turned on the blinkers. Took a wild guess and said to myself "Thermal failure! Crank position sensor!". I always guess that and I haven't been right yet.
Anyway, I wait a little bit for things to cool and try to re start it. Cranks just fine and I can hear the fuel pump kick on but I get no ignition. Check for codes, P0351 - Ignition coil primary circuit.
OK. So it could be power to or from the auto shutdown relay (B+ supply to coil) , could be the PCM, could be the ground wiring from PCM to coil, could be the coil. Most likely thing, if I can't see any obvious problems in wiring, is the coil. I'll check the wiring anyway and check for power / pulsed ground while it's cranking.
If the secondary wire (to the distributor) needs it, I'll replace it.
Anything else I should be aware of on these motors? I think I've got a handle on this one but damned if I wouldn't appreciate a second opinion... What say ye?
