Chevy Express/GMC Savana Starting/Stalling Problems
Go to start the van and if fires up for about one second then quits. Try and try it will not start. Dealer at first said it was the fuel pump. Replaced it. Months later still doing the same thing. It like the security system is telling the car not to start. After I let the van sit(1/2 hour to overnight) the van starts right up. I know of another Chevy (Suburban) that does the same thing. Starts, stops, won't start wait till later and then it will start. Can anyone help?
