Hello I have a 1995 Pontiac Grand Am with around 145,000 miles. I'm not really that experienced in car mechanics. The problem is that the car will not start. I hear the fuel pump working and the engine is turning over trying to start but will not start. I've read other similar questions that could also pertain to me. I.E. Ignition coil / housing. I think it is getting fuel to the engine but I don't know why it is not firing. Please help!
