My 2001 Jeep Grand Cherokee wont start sometimes, but if I put it in neutral then try to start it..It starts .. What is the problem with my baby.......


Test/Service/Replace

The circuit on newer cars with automatic transmissions has a neutral safety, or neutral start switch installed between the ignition switch and the starter. The ignition switch cannot operate the starter motor unless the transmission is in park or neutral.
Late model vehicles with manual transmissions have a starter/clutch interlock switch that requires the clutch to be depressed to the floor.
Neutral Safety Switch
Normal operations of a neutral safety switch provides a quick check for the adjustment of the gear selector linkage.
  • To do this, move the selector slowly until it clicks into the PARK position.
  • Turn the ignition key to the START position.
  • If the starter operates, the PARK position is correct.
  • After checking the PARK position, move the lever slowly toward the NEUTRAL position until the lever drops at the end of the NEUTRAL stop in the selector gate.
  • If the starter also operates at this point, the gearshift linkage is properly adjusted.
  • This quick test also tests the adjustment of the neutral safety switch.
  • If the engine does not start in either or both of these positions, the neutral safety switch or the gear selector linkage needs adjustment or repair.

CAUTION
Since you must work under the vehicle to adjust most shift linkages make sure you properly raise and support the vehicle before working under it. Also, wear safety glasses or goggles while working under the vehicle.
A voltmeter can be used to check the switch for voltage when the ignition key is turned to the START position with the shift lever in PARK or NEUTRAL. If there is no voltage, the switch should be adjusted or replaced.

Caravan won't start after shifter cable replaced


Make sure the transmission range selector switch is adjusted correctly it is the switch just below the shift cable post. Also try to start it in Neutral rather than park position.

Ignition switch won't release key when it is put in park. But when I removed switch and key tumbler, the key tumbler/cylinder releases key. Why won't the key release when it is in park?


Most newer models have a safety feature called
shift interlock. This prevents the key from being turned back
to the lock position if you forget to place the gear selector in park.
Depending on the model,
If it uses a cable, it may be sticking or needs adjusting.
If it uses an electrical solenoid. may be blown fuse or park switch.
Tap, shake, and pull up on the shifter and make sure it's in park.

Put a new engine in a 1998 isuzu rodeo now it won't start. I thought it was the neutral safety switch because the R was on the dash and it was in park


This could be the problem. If your dash indicator is showing reverse but the transmission is in park it could be the safety switch. I'm not talking about the safety switch in the transmission though. In automatics they put a second switch to kill the starter from engaging. You need to adjust the linkage. If your shifter isn't actually on the column but the indicators are there is a cable that attaches the floor shift to the column and that is adjustable. Put the Floor shifter in Park and turn the column section nearest the dash by hand until you find park. Then adjust the cable length as needed. If all you have is the column shift it is still a cable adjustment. Set the emergency brake, drop the shifter to low 1 and adjust the cable linkage by loosening it on the transmission and manually move it all the way to low 1 then tighten it down then move the shifter to park and repeat teh adjustment process to verify that it is properly aligned. Lock the linkage back down and see if the vehicle will start, if it doesn't move the shifter to neutral and try to start the vehicle if the vehicle starts then check the column shift safety switch at the park position to make sure it is still in place and working. Typically, if the vehicle won't start in Park or Neutral it is more likely to be the Transmission neutral safety switch.

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.

Problems starting problem is intermitent helps to move shifter out of park and put it back


It's sounds like the neutral safety switch is bad. When you turn the key to start the power goes from the ignition switch, to the neutral safety switch then, to the starter solenoid. When you say starting problem I'm assuming it won't even crank over. The car should also start in the "Neutral" position, there is an adjustment on that switch to, it may just be out of adjustment. If it cranks over but won't start then I don't see how the neutral safety could be the problem. The neutral safety switch is right on top of the transmission directly under the master cylinder for the brakes. You should be able to see where the shift cable connects to the transmission.

6. Install replacement shifter unit in reverse order of removal of original unit.

7. ADJUST CABLE: SEE FIGURE 1 (Below)
Loosen nut that fastens cable pin to transmission control arm. Loosen nut enough to allow pin to slide in the slot in the arm. Turn the arm to NEUTRAL position. Move the stick to NEUTRAL. Tighten the adjusting nut. Test movement of stick and check to be sure that stick positions agree with transmission control operation.


43402db.gif
8. SEE FIGURE 2 (Below)
Connect car battery. Apply hand brake. Move stick to NEUTR AL position. Press foot on brake pedal. Start engine. If starter fails to operate, Neutral Safety switch must be adjusted. Adjustment is made with a long-bladed Phillips screwdriver through the "Street" gate. This screw is directly in front of the st ick. Turn the screw about 1/2 turn past the point where starter operates. (STICK MUST REMAIN IN "NEUTRAL" WHILE ADJUSTMENT IS MADE). Starter should operate ONLY when stick is in PARK or NEUTRAL position.

My 2001 porsche boxter S 3.2 will not start in park, but will start normally in neutral, does anyone know why? (it's an automatic)


1.Shifter linkage could be out of adjustment, and not allowing the Neutral safety switch to be bypassed, when in the Park position.

The shift linkage, could move the arm of the neutral safety switch far enough, to bypass it when the shifter is in Neutral, but not far enough when the shifter is in Park.

2.Perhaps the Neutral safety switch is bad, or has come loose on it's mount, and is out of position.
