Check fuses I believe there is a main starter relay under the hood in the fuse box. Will it crank in neutral.

SOURCE: When i turn the key

Hello there geddas64,

When it clicks:
- Is it a series of rapid clicks? If so, this usually is indicative of a low battery state. If you have someone to give you a jump, try it again. If the jump works, run it for a while. Stop the engine, then try to restart. If it does the same thing, have both the alternator and the battery checked.

- Is it a single strong CLICK? If so, the problem is either the solenoid or the starter.

The solenoid contacts could be burned.
The starter could be bad.
The connection between the two may be damaged.

If you are comfortable under the truck, pull the starter.

See whats wrong:

  • Get some jumper cables.
  • Attach the negative (black) to the frame of the starter.
  • Keep the red (positive) cable away from the black.
  • Attach the other ends to the battery (+ = red, - = black)
  • Keep your fingers away from the gears.
  • Check the starter by touching the loose red jumper to the connection between the starter and the solenoid. DON'T TOUCH THE FRAME. If it spins, the starter is ok. If it doesn't replace it.
  • Check the solenoid by attaching the red cable to the bigger (and emptier) solenoid terminal.
  • You are going to need a test light or meter.
  • You will see a smaller terminal on the solenoid. Get a screwdriver and use it to cross this with the larger one.
  • You should hear that same CLICK. You should see the gear slide forward . In a perfect world it would spin too.
  • Attach the negative lead of your test light or meter to the frame.
  • Attach the positive lead or probe to the solenoids other large terminal (the one connected to the starter).
  • Recross the red jumper to the small terminal to simulate a start.
  • If the test light fails to light, the solenoid is bad. Replace it.
  • If it lights, check the connection between the solenoid and starter. Disconnect, clean and reconnect.
Thats the whole deal. If you have problems or additional questions, just click the ASK button.

SOURCE: replace neutral safety switch on a 1988 gmc sierra

Typically the Neutral Safety Switches are located with the gear selector, either in the column or the floor.

Hope this helps,

SOURCE: 2005 GMC Sierra 2500HD 6.0 Won't turn over

I have seen many ign switchs. Check to see if the theft doesn't flash when you try to start. It is still posable that the starter is going. Have someone crank the engine. Check for power on the purple wire. If there is power and the it does not crank. Check that the big wire has a soild 12 volts. You can use a screw driver and jump the purple and the big 12v battery at the starter and it should turn on if not replace the starter

SOURCE: my 2000 gmc sierra won't start. changed the

Just maybe it's mechanical.Internal to the steering column is an activator rod that manually makes the contact in the ignition switch.It's the cast piece that is molded to the activator rod that breaks.Two things you can do;tilt the steering wheel all the way up and try again to start(the cast piece spreads before it breaks,by tilting you gain a little extra throw on the switch).This will only work a couple times before complete failure of the casting.The other is to move the cover that's just below the tilt lever enough to get to the rod and move it with a pliers to start.If it's mechanical these things do work,I ran my truck with a vice grip for a couple weeks until I could get the parts for the repair,but replacing the broken part is smarter and won't scratch up your column like mine.

SOURCE: My 2002 GMC Envoy wont start. I have had it on

try car to car boost-battery charger may not be working correctly or set on low amp charge -interior lights and dash may all light but battery may not be strong enough to energize starter have battery tested if battery good than check for power to the starter if power-- starter may be shot can remove also and have tested at most auto stores free if no power battery -wiring-or connection issue would need to test fuse panel-ignition switch and starter solenoid

'88 Chevy Nova won't start

Won't start how ? When you turn the key to the start position what happens ? Anything ? Does the starter engage an spin the engine ? This would be a crank no start condition which would have me check for spark at a plug wire or hook up a fuel gauge an check for fuel pressure , doing a compression test . Or nothing happens when you turn the key . Which would have me test the battery ,voltage drop test the starter circuit , looking at a wiring diagram to see what all is involved in the starting circuit , relay , park neutral safety switch , PCM/ECM - engine computer .
You need to add more details .

Turn key to crank position and only once in a while.has new battery and starter ,wires on starter are good.

When the vehicle doesn't start, you will need to check the purple wire at the starter solenoid for power when the key is held in the crank position. If there is power during this procedure, the starter will be defective. If no power, possible ignition switch... neutral safety switch..starter relay ( if equipped ) or wiring problem

GMC 6.0L starter does not engage

To check the starter: key off, transmission in park or neutral, brake set. Pull off the small wire to starter solenoid. Then use a small jumper wire from battery cable post on the starter to the solenoid terminal (can also use a small screwdriver to bridge those terminals). Starter motor should engage the flywheel and spin the engine. If nothing, starter motor or solenoid is bad. If starter works, check for power on the small solenoid wire, with key held in crank. Wire should have power, if not, check start circuit from ignition switch to solenoid-the neutral safety switch is in that circuit.

I have a 87 Pontiac firebird. I got it from a friend and drove it home. I drove it a round town a little then parked it by my house. I went to start it and nothing happened, i thought the battery was dead...

Probably not a fuse. When turning the key to on, does it give indication of power in and power out of the ignition switch-do the warning lights and gauges on the dash turn on?
If the key switch is sending power, next thing to check is the starter motor. You could take it off and have it tested, it and the starter solenoid mounted on the starter, or you could do some quick electrical testing yourself, if you have a test light or multi-meter.

If you pull off the small purple wire to the starter solenoid on the starter, you should check if the wire has power when the key is held in crank position. If it does have power, the starter or solenoid is faulty. If no power on the purple wire in start, then power is lost between the key switch and the solenoid. This part of the start circuit includes the neutral safety switch on the transmission (or the clutch switch if manual transmission), and a starter relay somewhere under the hood. Check the neutral safety switch for continuity in park or neutral. The start wire out of the ignition switch goes to this safety switch, and power is passed on to the starter if gear is in park or neutral.
Not likely the starter relay is bad, but you may need to find and check it, if all else fails.

My 1994 Villager. When the key is turned the last bit to kick in the starter, nothing happens.

If the engine will not crank, and you know that the battery and starter are ok, the problem could be the key switch, the neutral safety switch, the starter relay, or a bad connection in the circuit.

My 92 lincoln town car will not start i have replaced the starter, the neutral safety switch and the battery but when i turn key nothing happens but can jump starter and will crank

Yes there is a starter relay in the wiring diagram.
The yellow and lite blue wire goes from the starter solenoid to the relay. There is a yellow wire from the relay to a 30amp fuse. The key switch powers thru the neutral safety switch and then powers the relay on.

Randomly won't start or even turn over, sometimes start fine. bouncing gauges

Yes it could be the key switch. You would need to check for power at the starter when it fails to crank. There is also a neutral safety switch in the circuit.

I own a 1996 hyundai lantra 1.6. I cant get it started. My battery's fine as i get radio and lights and all but when i turn my key to IGN nothing happens and I dont even hear the starter clicking.

Try moving the shifter back and forth while turning the key, the neutral safety switch is super sensitive, you may have bumped it. If not, try the anti theft device if it has one. Then go and check the wires, something has come loose, fuse blew, check it out.

I have a 2007 Cadillac CTS. I go to turn the key and nothing happens. All onboard elctronics and a/c are functional. Battery life shows to be good. I have also tried using my other key set and nothing....

Test the neutral safety switch by doing the following steps.

1)foot on brake
2)turn key to on position
3)shift lever to neutral (N)
4)start the engine
5)shift the lever to Park (P)

If the engine can start at N and not at park then it's the neutral safety switch.
