The parking light estay in reverse ,when is on parking and dont start the engine


Your shift indicator is out of alignment or your shift linkage is out of adjustment. If you have the shift lever all the way up and are sure it has locked into park try shifting to Neutral and see if you can start it in neutral. If it starts this is a simple adjustment. if it doesn't you will need to replace the neutral safety switch or have the TCM repaired at a transmission shop.

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.

Dead key all lights are ok carwont start no click click click


try starting it in neutral. sometimes the neutral safety switch thinks you are just outside of park (aka in reverse). this switch will not allow the car to start in any gear except park and neutral. also, try shifting firmly in and out of park several times. this may trip the switch. good luck

Engine will not turn over or start when in park with key on.


You linkage is working properly it sounds like, especially if the indicator for "D, R, N", etc are lining up. However the linkage or the neutral safety switch may need to be adjusted. More than likely, it's your neutral safety switch.

The brake pedal release has nothing to do with the neutral safety switch when switching gears.

The brake pedal release is just a safety to prevent you from pushing the gear shifter accidentally. Actually, you should be able to start the truck without holding the brakes.

If the neutral safety switch is bad or misaligned, it'll do exactly what you're describing. If pulling it down in neutral starts the truck, then that's a sure indicator.
