Pontiac Sunfire '95 wont start

READ THIS ALL BEFORE YOU DO ANYTHING
NOTE: some vehicles have the starter relay and starter mounted together as 1 unit. Sometimes the starter relay and starter are seperate. When I refer to "relay" it could also mean the starter and relay as 1 unit.
Note: "starter switch" is not to be confused with "key switch", although sometimes they are all one unit. The starter switch is usually mounted on the steering column and actuated by a metal rod. On units that are all one unit, the keyswitch/starter switch (both one unit) will have to be replaced. (this is a rare problem, so don't get worried just yet)
1. Check battery voltage, should be between 12.5-14.5 volts. if low voltage replace or charge battery, and try to start car, if it don't crank with new or charged battery, move on.
2. Check connections on the starter relay, even the small one coming from your starter switch. if loose or corroded, clean with a brush and reconnect them. Try to start your car. Did it start? if not, Move on
3. Well now we know the connections aren't the problem. How about a click? did you hear one? If a click is heard, go to #4, if nothing is heard, go to #5
4. Well at least the relay is clicking, but nothing else is going on. The relay is working, so the starter must be bad. Replace the starter and start your car!
5. Humm, connections aren't the problem, maybe the relay is bad, replace your relay with a new one. Move on
6. Now we have a new relay, with clean and tight connections. Start your car. Does it start? If yes, then HORRAY! we fixed it. Does it click? If so then goto #7, If it don't click, then goto #8
7. So here we have a new relay, with good connections that will click when trying to start the car, but nothing else happens. Starter is faulty, replace the starter, and off you go, see ya!
8. So here we have a new relay, with good connections, but it still won't click when we try to start our car. This means that your starter switch is faulty. Replace starter switch and try to start your car. Vroom! finally done with this car problem!
List of shortcuts: if you remove the starter switch lead (small wire) from the relay and apply +12v to its respective prong or lead on the relay, and your starter cranks, your starter switch is faulty. You can actually hook up a starter button this way. If you jump the two large wires together on the relay and it cranks, then the relay is faulty. If you jump the two large wires together and nothing happens, then starter is faulty, or wires to starter are loose or broken.

Check for a faulty starter relay in the engine compartment fuse center

starter could be gone, simple, can ytou push start the car??

If you can jump start it from another vehicle , the starter is not the problem. Most likely a low battery , or dirty connections at the battery posts / cables.

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.

When you turn the key, does the starter relay click? Could be the heavy connection from the battery to ground or to the starter solenoid. Make sure these connections as well as the battery terminal connections are clean and tight.

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.

gearshift switch not plugged in or faulty.

there should be a large battery cable red going to the large terminal of the solenoid, another thin wire going to the flat blade connector which should go to the starter switch, The way to test the wires to find out which one is the ignition switch wire is to get someone to sit in the car and turn the ignition key as if to start it and you can use a simple test light to see which one goes on and off as the ignition switch is turned on and off.
There should be another wire that connects to the same terminal as the battery cable which goes to the altenator, about twice the size as the small wire is. If there are any more wires I am not sure where they will go to.
Hope that works for you

Its likely that you have either a bad ignition switch or a bad neutral safety switch (if stickshift, clutch switch) Try starting in neutral...if it starts, change neutral switch (jump across clutch switch, check starting in neutral with your foot on the brake) Ignition switch is on top of steering column under dash.
