What causes a Grand Am to be unable to start?
No Ignition. A damaged or failed fuel pump can cause a Grand Am to be unable to start. The engine cranks (noise of the engine attempting to turn over), but the vehicle is unable to send fuel to the engine to start it. This is often the case when the fuel pump has failed entirely and is unable to maintain fuel pressure into the engine.
Where is the fuel pump relay on a Pontiac Grand Am?
The fuel pump relay is #18 in the fuse box. Start with the car off, and have somebody else put the key in the cars ignition and attempt to start the car while you listen to the relay. If you can hear this relay make a “clicking” noise as the car attempts to start, then it is working properly.
What causes a Grand Am engine to misfire?
You will experience dipping RPMs and a shake in the engine block when the car is sitting still, which leads to engine misfires when the vehicle is accelerating and attempting to retain speed. A Grand Am’s fuel injectors are highly sensitive to fuel pressure, so these signs could emerge very early in the fuel pump’s failure.
