I will go with a VP44 failure. the failure rate of ECM to VP44 is probablly one ECM to 10,000 VP44's. And that failure was probably caused by shorting the alternator control circuit. VP44's in electrical fail mode are really wierd.

Pulled two codes P0336 & P0602... What Now
I checked my code on my odometer first and came up with P1693 Pdone so I just bought a OBDII scanner and pulled these two codes: P0336 & P0602. I looked up the codes and the P0336 indicates crankshaft sensor and the P0602 indicates ECM internal fault condition. My local dealership told me I needed a new ECM. Does this mean my ECM is toast something else?
