Any Ideas why my 2007 Cobalt won't start.
The car has a strong battery and turns over very well, has great fuel pressure to the rail and great spark from the plugs and good compression, yet will not start. It's as if all the injectors will not open. I can get the car to briefly run when spraying fuel directly into the intake. There are no waning lights on and a check of the on-board diagnostic system shows no trouble codes. I am thinking the ECU, engine control unit, or some safety lock out system I am unaware of. Any ideas?
