01 cavalier 2.2 SFI often won't start. Now we have a new battery, starter & altenator. The car block heater is plugged in even when not very cold outside. It has spark, u can hear the fuel pump!
Seems like no reference pulse(fuel to injectors) or no fuel being sent through injectors? Before we purge or buy injectors. Any ideas would be helpful
P.S. Where is the fuel pressure bleeder valve if any?
