1997 Pontiac Bonneville eagine won't start

Hello -

Based off of what you are saying it appears to me that it is your fuel relay. I have attached information on that and the location of the relays. Relays N30 and N85.

When the key is first turned ON the PCM energizes the fuel pump relay for two seconds to build up the fuel pressure quickly. If the engine is not started within two seconds, the PCM shuts the fuel pump OFF and waits until the engine is cranked. When the engine is cranked and the RPM signal has been detected by the PCM, the PCM supplies 12 volts to the fuel pump relay to energize the electric in-tank fuel pump.

An inoperative fuel pump relay can result in a no start condition.

An inoperative fuel pump would cause a no start condition. A fuel pump which does not provide enough pressure can result in poor performance.

Hi alsd48 and welcome to 2carpros

Check the fuel pump fuse no.6 20amp, also check/test the fuel pump relay and fuel pump speed control module-the power goes thru these components before it gets to the fuel pump
