I have a 2004 3.4l grand am that has not started cold since nov1/10, only starts if we plug in block heater. We have spent $1,000 so far trying to troubleshoot at GM and they cannot find whats wrong, running out of patience and cash, we have replaced crank, cam, coolant sensors, new battery, only sensor we haven't replace is air intake temp sensor. Fuel pressure is ok, replaced air and fuel filters and a new ECM, STILL NEEDS MORE DIAGNOSIS. I would appreciate any other advice,
have the same problem?
