1996 sunfire will not turn over/start

This could be a couple different things causing your No-start condition. first thing I would check (Battery is good) access the starter solenoid, the small single wire connection is the start signal. Test for 12 volts here with DVOM or test light while someone turns the key. If there is 12 volts reading, the starter solenoid is defective. If there isn't 12 volts reading check all the fuses (with test light).
The second item causing the trouble could be the Neutral Safety Switch (Auto Trans) or Clutch Safety Switch (Manuel Trans) These could be open or out of adjustment.
Hope this helps you...

check at the starter for a fuseable link wire as well as at your fuse panel for a possible blown fuse or a bad relay

have the starter checked ok.go to a near by autoparts good luck

When jumped off ,if it drags to start,have the starter checked,and if when jumping the car off,the starter turns the engine over real good,then the cables are most likely the problem,replace them.

I would check the Maxi-Fuses, you may have blown the main fuse.

Check all your fuses..It maybe just your fuse for the ignition...which in fact turns your starter over.... And yes your starter is good, if it tries to crank when you jump it..Now if your fuses are good, then yea your problem mat be the ignition switch itself....But check all your fuses first...Goodluck...

starter relay,ignition switch,park switch.need to use a volt meter and start at the starter,see if you have at least 12 volts.if there is have the battery tested.does your head lights come on?next no voltage, go to the fuse box under the hood and check for (2) 12 volt powers with the key on and a good ground.if ok replace the relay.next move the trans shifter to neutral with foot on brake and try and start if it starts you need park switch.if not next is the ign.switch to test,you will need to locate the starter wire and check for voltage when starting if none replace the ign.switch hope this helped.also the alternator has nothing to do with the cranking of the engine on this car.

if you had the starter recall done, there is a relay mounted near the center of the radiator that controls start power. Pontiac dealer sells the part.

Replace the starter relay,It is located in the fuse box under the hood

I would first verify battery power, Once you have proper power there, either via a good trickle charger or battery replacement, I would check the fuseable links mounted right at the "hot" side of the starter. Just follow the 4 gauge wire from the battery to the 15mm/13mm nut on the starter. Make sure you have power to both sides of the wire with a test light. THis is the only wire that supplies the power for the relay fuse box. So either your not making power, or the power isn't reaching this box. Let me know how you make out.
