    the engine does not turn over, so i don't see as the fuel delivery or the ignition system could be the problem.

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.

Bad excelleration. Dies when let up on gas.


Pull your IAC (Idle air control) off and spray clean it & the port it came out of with throttle body cleaner. Spray pintle (pointed part) good and clean, then re-install & try it. If it's cured & starts to act up again later, replace it.
Should be mounted near front of throttle body, on side.

Sounds like a ground issue. Look for any ground points around the area of the engine where you were. There are several bolts that have ground wires attached on the manifold and head areas.
