So I've had an issue with starting(runs fine, just starting is the issue)after the car has been sitting. If I start it within an hour or so it's fine but if it sits longer than that it will crank & crank for 10-30 seconds before finally firing up & I have to pump the gas pedal to get it going. Losing fuel pressure right? So is this the pump? Check valve? Control module? I checked & there are no fuel leaks & injectors are good.
