Hello, my name is Bobby. Thank you for the question. Can you tell me if the fuel pressure drops to 0 when this occurs?

Customer: replied 2 years ago.
I don't believe so, I think that it falls below the threshold- (I am not the mechanic on this one)
Customer: replied 2 years ago.
in fact, pressure drops about 15 lbs

Thank you. The pressure needs to hold when this occurs. If it is not then you either have a defect in one of your new pets or you may have a failure in one of the fuel injectors causing one of them to stick open.
