If the security system was the problem the light would be flashing in the dash indicating activation and lock out.

SOURCE: vehicle will not start

try having someone turn the key to the start position while you tap on the starter it may be jammed or you might check for misallignment of the starter and make sure it is wired right.

SOURCE: Car starts sometimes - sometimes it doesn't -

Try shifting the shifter when this happens to see if it is related to the PRNDL in the transmission; you of course will have to have the key in on possition to attempt this. If this doesn't work, you will need to take it to a quaified mechanic since there are serveral test that will be needed to be find this issue, but let me assure you that the security light comes on and blinks often when starting the vehicle.

SOURCE: neutral safety switch 1991 camry 4 cyl

Well, not necessarily need a professional if you have some basic maintenance experience.

If you look at the engine compartment from the front of the car, the switch is located at right side, very close to the radiator, close to the bottom of the car. You will see the shifting cable as well as an electronic connector on it. You can try if you shift, the cable will rotate the arm on the switch.

According to my experience, it's not easy for the switch to go bad, it may just need some alignment so the switch angle is zeroed in wrt the contact points. There is a line on the switch for alignment purpose.


To replace it is not difficult at all, once you located it, you will see. You can get a used one at junk yard, I believe it will be much much cheaper.

Car will not turn over it has a new battery ,starter and selinoid and alternator. ItS a 1992 Cadillac Devvile kop


Power goes from ignition switch to neutral safety switch then to starter. Neutral safety switch used to be on steering column. Find wire harness for switch. Verify power is coming to harness when key is in start position. If not then bad ign switch or blown fuse. If power is coming to neutral safety switch but not going to starter then either bad switch or out of adjustment. Try putting car in neutral and starting then back to park. Or you have funky aftermarket alarm that is disabling starter. Also if car was financed thru small car dealership they may have put gps with starter disable on it. This helps remind you that payment is due. You can run jumper wire to starter solenoid to make starter turn over. That would be the small terminal.

It could be the neutral safety switch which prevents you from cranking the engine in gear.
But it could also be the anti-theft system. The system reads the chip in the key to allow the starter to crank the engine.
Is the security light staying on ?

Brake lights


No, not that switch, but the brake light switch on the brake pedal. It may just need adjusting to turn off when brake pedal is not pressed.
The neutral safety switch is in your starting circuit to keep car from starting when not in park or neutral.

Replaced battery for 2001 cadillac deville but not wont turn over ....i have power but just wont crank whats going on?


Electrical problems require tracing from where you have current to where you do not. For example, it could be dirty battery terminals, back chassis ground connection, missing engine ground strap, bad neutral safety switch, bad ignition switch, bad starter solenoid, bad starter field or armature brushes.
See if there is current at the starter solenoid, when you try to crank it, with a test light. They move further upstream if there is not.

How to replace neutral saftey switch on a 1980 cadillac deville?


Use like reference guide for GM Cadillac 1967-1989 Repair Guide Neutral Safety Switch - REMOVAL & INSTALLATION

All Except 1985-89 Eldorado and Seville
See Figure 1
The neutral safety switch prevents the engine from being started in any transmission position except Neutral or Park. The switch is located on the upper side of the steering column under the instrument panel on column shift cars, and inside the shift console on floor shift models.
  1. Remove the console for access on floor shift models.
  2. Disconnect the electrical connectors.
  3. Remove the neutral switch.

To install:
  1. Place 1967-70 column shift lever models in Drive, and 1971 and later models in neutral. Locate the lever tang against the transmission selector plate on column shift models.
  2. Align the slot in the contact support with the hole in the switch. Insert a 3 / 32 in. (2.38mm) diameter pin in place. The switch is now aligned in Drive position.

1973 and later neutral safety switches have a shear-pin installed to aid in proper switch alignment so that insertion of a pin is unnecessary. Moving the shift lever from Neutral shears the pin.
  1. Place the contact support drive slot over the drive tang. Install the switch mounting screws.
  2. Remove the aligning pin. Connect the electrical wiring, and replace the console.
  3. Set the parking brake and hold your foot on the service brake pedal. Check to see that the engine will start only in Park or Neutral.

ADJUSTMENT
See Figure 2
1974 and later cars do not have a neutral safety switch. Instead, these cars have an interlock between the lock and the transmission selector, which is non-adjustable.
  1. Place the shift lever in Neutral.
  2. Move the switch until you can insert a gauge pin, 3 / 32 in. (2.38mm) diameter, into the hole in the switch and through to the alignment hole.
  3. Loosen the switch securing screws. Remove the console first, if necessary.
  4. Tighten the screws and remove the pin.
  5. Step on the brake pedal and check to see that the engine will only start in Neutral or Park.

Fig. 2: Adjustment of a common neutral safety switch


1985-89 Eldorado and Seville
See Figure 3

All neutral safety/back-up light switches come with a small plastic alignment pin installed. Leave this pin in place.
  1. Place the shifter assembly in the Neutral position.
  2. Remove the shifter lever-to-switch nut and the lever.
  3. Disconnect the electrical connector from the neutral safety/back-up light switch.
  4. Remove the neutral safety/back-up light switch-to-transaxle bolts and the switch from the vehicle.

To install:
  1. Position the shifter shaft in the Neutral position.

If using an old switch or the plastic pin (new switch) is broken, install a3/32in. (2.38mm) diameter pin gauge (drill bit) into the neutral safety/back-up light switch; the switch is then locked into its Neutral position.
  1. Align the flats of the shifter shaft and the neutral safety/back-up light, then, align the switch-to-tang on the transaxle. Torque the switch-to-transaxle bolts to 22 ft. lbs. (30 Nm). Remove the pin gauge.
  2. To complete installation, reverse the removal procedures. Make sure that the engine starts only in the Park and Neutral positions.

Neutral switch 1993 cadillac


The neutral safety switch is on the top of the automatic transaxle (under the hood). You have to remove the air cleaner assembly for access to this item. Once the air cleaner is off, you can see the switch mounted on top of the transaxle.
Remove the shift linkage, electrical connectors and vacuum hose as needed.
Remove fuel line bracket if needed.
Remove mounting bolts and nuts to remove the old switch.

Install new switch as reverse of above.
Put shift lever in neutral.
Align switch so it's alignment hole and the matching tang hole line up. Tighten down the switch mounting bolts. Verify that the engine starts in PARK and NEUTRAL. Re-adjust if it doesn't.
