The camshaft position sensor was replaced @ 201,000. 2 weeks later, the car stalled in traffic and would not restart. No DTCs presented. There was no spark at the #1 plug, the tube was half full with oil. Replaced valve cover gasket, tube seals, plugs and wires. No spark.
Broke crankshaft position sensor receptacle while removing connector, replaced sensor. Still no spark, no codes. Tested starter due to never having heard car start, and was not impressed by sound of cranking. Starter and battery both checked sat.
No +12vdc @ coil with key on. Jumpered ASD relay, and saw +12vdc @ coil center pin. No start. Swapped horn relay (known good0 no start, no +12vdc. Fuel pump runs, pressure @ fuel rail. Voltage drop @ starter w/in limits. Replaced PCM w/ known good, no start, same conditions, no codes.
Timing belt is intact, pistons cycle with starter. If the presumed original timing belt (owner has never replaced belt since 75K), had jumped timing, I would expect to see an out of sync code> Nope
I've gone to alldata, as Haynes manual has no engine control info.I have schematics, have exhausted all troubleshooting ideas. Could the flywheel be worn to the point it is not spinning the engine fast enough, and setting an ASD shutdown command?
What parameters, exactly, cause the ASD relay to shut off? The owner really likes the car, which is in surprisingly good condition, and really can't afford to replace it now. All help would be greatly appreciated.
