2001 Pontiac Grand Prix won't start. Bought a new battery and new starter. Starts a few times then won't.
If it sounds like it wants to start then it could be the position sensor. Look for the ignition module in the center-rear of the engine ,,, on the drivers side of the module are 2 small wires going down the back of the engine ... you can unplug it and have someone check it with a meter while cranking the engine .. it should pulse. Sometime the exhaust pipe will melt the insulation. If that's not the problem can you give us more background ?
It starts about 5 times you can drive it, and everything. Then it won't start all it will do is click. All the inside lights will still be have power.
Check your battery cable connections at both ends. Make sure everything is clean and tight. When this happens, try starting it in neutral. Also, when this happens, switch on the headlights and try to start it. Do they stay nice and bright? If so, it's going to be the neutral safety switch, bad starter, or a security system problem. If the headlights, dim, flicker badly, or go out, it's going to be a bad battery cable connection. HTH. -Jim
