Did you ever get it fixed? What was it? Was it the crankshaft position sensor?
Here is what I found in a repair manual.......
---------------------------
This no-start test checks the camshaft position sensor and the crankshaft position sensor. Refer to the ignition coil tests before commencing with this test, much time may be saved if the problem lies within the coil.
The PCM supplies 8.0 volts to the camshaft position sensor and crankshaft position sensor through one circuit. If the 8.0 volt supply circuit shorts to ground, neither sensor will produce a signal (output voltage to the PCM).
When the ignition key is turned and left in the ON position, the PCM automatically energizes the Auto Shutdown (ASD) relay. However, the PCM de-energizes the relay within one second because it has not received a crankshaft position sensor signal indicating engine rotation.
During cranking, the ASD relay will not energize until the PCM receives a crankshaft signal. Secondly, the ASD relay remains energized only if the PCM senses a camshaft position sensor signal immediately after detecting the crankshaft position sensor signal.
---------------------------------
So, I think it will end up being the camshaft position sensor that has failed. The car will run without the cam sensor signal. It may not run well, but it will not shut down. I feel that the cam sensor is getting warmed up and is losing connection internally. I will find out and we will get to the bottom of this.
No car has ever beat me. I am one of those guys that refuses to allow a machine to conquer me. Ha Ha.
