Car, Montana 2002, began rough starts (fuel pump not turning on at ignition), it was an intermittent problem, then sometimes not starting for days. Mechanic ran an extra wire from a nearby fuse socket to wire going to fuel pump to bypass fuel pump relay (replaced but apparently not the problem). Car ran well for a few months, but started having hard starts and then periods of not starting again. Car has just finished a two month cycle of running without out a problem and starting to have hard starts again. What is the problem: new fuel pump relays did not help, though computer diagnostics pointed to it.

SOURCE: Fuel Pump Relay Switch

Underneath your hood, behind the passenger side headlight, behind the core support, is a bank of 2-8 relays. One of those relays is the relay needed for your fuel pump. There will also be a fuel pump relay fuse located there. The relay designation should be on the cover of the relay compartment.

If you replaced the fuel pump then there is a possibility that during the job then some debris from the tank and/or filter got loose somewhere into the fuel system and is in your lines. It could even be a very tiny speck of gasket material, old or new.

Is the security light active? If yes it will have to get reprogrammed by the GM dealer as GM has this as a propriatory system... Meaning no one else can work on it.
