1999 Pontiac Grand Am Chk Fuel flow

Did you use a gage and check fuel pressure? Some of the national brand auto stores used to loan out a fuel pressure gage, if you don't have one. How long since a tune-up? Can you check for any applicable trouble codes? At the least, you would need an obd2 code reader. As far as no code diagnostics, the list of possibilities for start and die, is probably as long as your arm. I will copy and paste, if you need it? Oh, I didn't think to ask about your security system, is the lite on or flashing?
