TransAm LS1 2000 many error codes
I hope someone can help me.
The car starts but when the clutch is dropped the car dies. It has these error codes:
PO335 Crankshaft position ckp sensor circuit
PO418 Secondary air pump control circuit
PO645 air conditioning a/c clutch ralay control circuit
PI637 Generator l-terminal circuit
U1016 loss of PCM communications
any ideas what this might be ?
I bet this in turn has drained your battery, hence the loss of comms with the PCM.
Your A.I.R. codes I would not worry about right now.
Your code PO335 Crankshaft position ckp sensor circuit - is something to worry about but if you really had a problem the car probably wouldn't start at all.
NEXT STEPS:
Fix your alternator issue
What RPMs does your engine idle at in neutral (without pressing the clutch)?
Is your car stock? Any work done recently?
