I have a 2003 Pontiac Grand Am that would not start. All the lights, power windows, radio etc. work, but when you turn the key it is silent. It won’t even jump start. I had also put in a new solenoid, tightened the battery cables — still nothing.
“Starting” a vehicle includes the starter motor, the ignition system, fuel system, security system and a flock of other considerations. Unable to “crank” or “turn over” the engine reduces the number of components to consider.
Turn on the headlights then place the ignition key to start. Do the headlights dim at all? If not, it’s likely the solenoid isn’t getting any control signal at all. If the headlights dim, it’s possible the starter motor has seized or the battery is incapable of providing the required cranking amps. Remember, a faulty battery can cause a jumpered battery to not perform too!
Next, place a voltmeter or test light on the control wire of the starter solenoid (the solenoid is mounted on the starter) then place the ignition key in the start position. If the test lamp illuminates, the problem is with the solenoid (new solenoids can be defective,) the starter motor, the battery wire to the solenoid or a defective ground connection.
If the test lamp does not illuminate in the above test, the problem may include the ignition switch, the neutral safety start switch (park lever not properly engaged,) security system (if any,) wiring, fuses or a host of other possibilities. Report back with your progress.
So im not sure if you all figured this out yet or not but ill give you my experience. So last Friday our 2003 Pontiac Grand Am GT ignition switch locked up. Well I had it towed to the dealer because they said it had a recall on the switch. Well they told me that they couldn't perform the recall because we didn't have the factory keys. So I found it on the ignition switch in the parking lot with a hammer Got the switch to turn over, well whenever it went to turn the car wouldn't turn on wouldn't crank but all the lights on the Dashboard Light Up Windows air conditioning heat everything worked for the car wouldn't crank so I had the car towed back to the house install a new ignition switch waited the 10 minutes whenever I put the new ignition switch in for the security light to go out went to start the car same thing wouldn't turn over what make it sound. So after checking all the fuses mess around with wiring I decided to take the radio out reach behind the ignition switch to wiggle some wires well if you feel to the back of the ignition switch there's a big cluster of wires if you wiggle on those wires as you turn your key on as your starting the car the car fired right up so I think it's just some loose wiring maybe that will help some of you
