2004 grand am gt 3.4l car wont start cold, well it is 20 deg celcius and the car wont start unless the block heater is plugged in and the coolant reaches 90 deg ferenheight then it fires up and runs fine. I have changed both crank sensors, cam sensor, ignition module, coolant temp sensor. Car had me stumbled for weeks now. When coolant reaches 80 deg. Ferenheight or lower, the car will not start unless I plug in the block heater to warm up the coolant. Fuel pressure test came back ok, and spark does not seem to be the issue.
thank you hope to hear from you soon
have the same problem?
