SOURCE: wont start

There's only 2 more things that I can think of, check the fuse for the ignition, then the computor itself, you did everything else.It might be the problem and may not.

Have you tried to jump power directly on the starter? make the BIG power cable touch the small one on the starter with it still in the engine.(power touching the starter solenoid) use a LONG screwdriver to make them touch. you will not get shocked just make sure you only touch those 2. it will spark a bit but just hold it on there. if your starter clicks and does nothing then you have a bad starter. if it works then you have other problems.If it starts to smoke stop and make sure your engine is not frozen by turning the crankshaft with a large ratchet.

make sure voltage flows WHEN cranking also. check voltage at the starter while cranking. make sure it maintains 12 volts. or very close to it. nothing below 10.8 volts. check for corrosion on battey cables if voltage drops below that. that shows you have a curremt problem. also check grounds. or make new ones you know are good.

Good luck

As of 1994, the neutral safety switch is referred to as a Manual Lever Position Sensor (MLP).
  1. Disconnect the negative battery cable.
  2. Raise and safely support the vehicle on jackstands.
  3. Disengage the harness connector from the MLP sensor.
  4. Remove the 2 sensor attaching bolts and remove the sensor.
To install:
  1. Install the MLP sensor and install retaining bolts. Do not tighten, the sensor requires adjustment.
  2. Adjust the MLP sensor then tighten attaching screws to 80-100 inch lbs. (9-11 Nm).
  3. Remove the jackstands and lower the vehicle.
  4. Connect the negative battery cable.


ADJUSTMENT

C6 Transmission
  1. Hold the steering column transmission selector lever against the Neutral stop.
  2. Move the sliding block assembly on the neutral switch to the Neutral position and insert a 0.091 in. (2.3mm) gauge pin in the alignment hole on the terminal side of the switch.
  3. Move the switch assembly housing so that the sliding block contacts the actuating pin lever. Secure the switch to the outer tube of the steering column and remove the gauge pin.
  4. Check the operation of the switch. The engine should only start in Neutral and Park .

4R70W Transmission

  3. Align all 3 slots on the MLP sensor with 3 tabs on the tool.

have same problem, ratan9 solution is pretty junk and I dont know why waste time posting it. After talking to local shop, to "test" the neutral safety switch, try to start in neutral, try to move shifter "farther" into park and turn key, listen to any clicks possible. If moving to neutral starts it you've got a bad switch. All the searching i've done it's either the safety switch, the ignition switch or a short in the harness somewhere

The van will not shift out of park when started.

  • Neutral safety switch sends a signal to the on-board computer to allow the engine to start and to engage the transmission
  • When not replaced, vehicle may experience no start and/or transmission will not shift out of park.Here's the part Damon.

2003 ford tarus starter will not turn over replaced starter , neutral safety switch, ing switch but still it still will not turn over and I jump it over at the starter and it will start but it will start...

Probably the solenoid not pulling in. Check connections to solenoid from battery. You should hear a loud click when turning ignition switch to start. Also, a real trap, make sure your auto park switch is working. Like, if you are in drive, the starter won't crank.

Neutral safety switch What is it. Son pulled key out of ignition with the tramission not in park.Can not even turn ignition switch over. Is the neutral safety switch the problem

A neutral safety switch will stop the path of battery power going to the starter motor if the gear shift isn't in park or neutral. I dont believe your issue is here, I would say the ignition lock assembly.

Starter won't engage

It's most likely the neutral safety switch. Try putting the shifter in Neutral and slipping it just a little toward Park and see if it'll crank. If it does the neutral safety switch is the problem but worn linkage is the cause.
You've already check or replace everything else so it has to be this or the ignition switch.

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.
