    99 Dodge Neon. Car won't start. Key will turn all the way forward and lights and radio and stuff come on, but the engine will not even try to turn over. It is exactly what happens like when you leave your car in drive and turn the motor off, then later when you try to start it, it won't because it isn't in park.

I have had this same problem on my 1996 Caravan SE. Van runs great, but you can park the car and go into a store or restaraunt, and come out and the car won't crank. Just like the previous poster said, it's as if the van is not in park, when it won't start. Everything else electrical still functions.

But I finally solved the problem.There is an area just under the brake pedal that has some sort of switch, sensor, or wiring juction underneath the carpet. When I just lightly tap with my foot in this area, and then try to start the van, it fires up immediately. And this little trick works EVERY TIME to get the van started when it decides it doesn't want to start. Sounds weird, but this models history of strange electrical system behavior is legendary. Just like as it's well-known transmission issues. So try looking under your brake pedal for the cause of a no-start....

96 Plym. Gr. Voyager (same as Dodge) 4speed A/T can't locate neutral safety switch on drivers side front of trans. My book shows different location/picture (Haynes manual). Any ideas where to get picture/diagram for reference? Initial problem van starts normally but often only clicks when key is cycled through start cycle until it finally starts. Battery good (3 yrs and checked good), replaced ign. switch behind key tumbler assembly(NAPA Echlin part), relay at fuse block in engine area a checks OK with VOM meter, next item is neutral safety switch that also runs backup lights. I've opened area by removing air filter assembly for better view from top or under car but my switches are not in same location as Haynes book shows. Van has towing package and lockup torque convertor if that makes difference. Need source for diagram of trans exterior. Tha nks to all you helpful souls!

Why do I have to wiggle it around in neutral to get it to start again?


sounds like the neutral safety switch. i have replaced a few on ford trucks. after a while they tend to wear out or get out of adjustment. but if you wiggle it around and it starts. my guess is the neutral safety switch. you didn't specify what kind of vehicle you have but there are a lot of videos on you tube that may show you how to do this. good luck

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.

Test/Service/Replace Neutral Safety Switch
Most neutral safety switches are combinations of a neutral safety switch and a backup lamp switch. Others have separate units for these two distinct functions. When the reverse light switch is not part of the neutral safety switch, it seldom needs adjustment, as it is directly activated by the transmission or the gear selector linkage.
f_ttat_t3.20.jpg Typical location of a neutral safety switch on a transaxle. Reprinted with permission of Ford Motor Company. A neutral safety switch allows current to pass from the starter switch to the starter when the lever is placed in the P or N position. Some neutral safety switches are nonadjustable. If these prevent starting in the P or N position and the gear selector linkage is correctly adjusted, they should be replaced.
To adjust a typical neutral safety switch:
  • Place the shift lever in neutral.
  • Loosen the attaching bolts for the switch.
  • Using the angling pin, move the switch until the pin falls into the hole in its rotor.
  • Tighten the attaching bolts.
  • Recheck the switch for continuity. If no voltage is present, replace the switch.
  • The switch sometimes controls the operation of the back-up lights also. With the engine off and the key on, put the selector in reverse position. Check the back-up lights to see that they are on. Then, check in the drive position to see that they are out.

When I have a no start condition I work the maul selector from park to low 1 back and forth and the car starts


Your safety interlock switch is going out or is not adjusted properly. There is a procedure for adjusting the switch. The switch is on the transmission in the engine compartment. If you want to adjust the switch, loosen the botls holding the switch and follow steps 7-8 below. Else, you can just replace the switch entirely by following all steps.

The neutral start and backup switch are one unit mounted on the top left end of the transaxle. The neutral start portion of the switch allows electrical current to travel to the ignition system when the shift selector is in park or neutral only. The vehicle will not start when the selector is in any other gear. The backup portion operates the rear backup lamps when selector is in the reverse gear.


REMOVAL & INSTALLATION See Figures 1 and 2

  1. Make sure the shift selector in the Park position, then apply the emergency brake.
  2. Disconnect the negative battery cable.
  3. Disengage the neutral start switch electrical connector, then remove the shift control lever on top of the switch.
  4. Remove the two neutral switch attaching bolts, then remove the switch.

  2. Loosely install the two attaching bolts and washers.
  3. Insert a No. 43 drill (0.089 in.) through the hole.
  4. Tighten the attaching bolts to 7-9 ft. lbs. (9-12 Nm), then remove the drill.
  5. Engage the switch electrical connector, then connect the negative battery cable.

Bronco wont start 88 ford bronco just replaced tranny and now won't start. i've hooked everything back up but one of the wires to the transfer case bc i broke the plug in. any ideas why it wont start...


The neutral safety switch is located on the side of the transmission and it is usually attached behind the shifter linkage and it is secured with two small bolts that can be loosened up to allow for adjustment of the neutral safety switch.

To adjust the neutral safety switch place the transmission into neutral, (block the tires) there is a notch or and indent marker on the housing of the neutral safety switch that should be lined up with a line on the face of the collar that is around the shifter detent shaft, and if they are not in alignment then loosen the two bolts that secure the neutral safety switch and then turn the neutral safety switch until they are aligned and then tighten the securing bolts to the neutral safety switch, and then test the starter. If the starter fails to engage then either the neutral safety switch is faulty, the neutral safety switch has been by-passed all this time and the by-pass (I will usually find things like a paper clip shoved into the vehicles wire connector with electrical tape around it) has fallen out of the wire connector from the vehicle wiring harness, or the battery just went dead. if you have the neutral safety switch from the old transmission still available try using it to test the neutral safety circuit. I have provided you with an image to help assist you adjust the 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.
