1989 Pontiac Firebird Repair Question
Why will the car start but only run for a couple seconds
I think it may be related to another issue. I looked and there is not an, "Immobilzer" which is part of an alarm system that cuts the fuel pump off when a car is being stolen. So I am giving you a walk through diagnostic to help with the problem. When you get to the section about pulling codes or if you need special tools to do a fuel pressure test. Advance Auto or Auto Zone will pull codes for free and loans out specialty tools for free.
