Question about 1988 Ford F 150

Neutral safety switch....I think

88 F150 5.0L v8 2WD 5 speed manual:
Can no longer press in the clutch and start the truck. Battery is fine. dash lights work. Amp meter shows charge. I noticed previously that I had to press the clutch in agaist the floor to be able to start the truck. How hard is it to replace the neutral safety switch? Are there schematics/diagrams/instructions available?

    The switch was right where you indicated. It was cramped but relatively easy to replace...Unforturnately, it didn't fix the problem. The truck still wont start. Other ideas??????

The switch is located at the top of the clutch pedal assembly, above your feet. Its a little cramped, but its a simple dc two wire switch, you should be able to check it with a meter for power and to see if the switch does indeed need replacement. If thats the problem, when you see the new switch, you'll know it goes in, very easy. good luck

Neutral safety switch location


If you have a 5-speed manual transmission, you're probably looking for the clutch safety switch, which is located on the clutch pedal under the dash near the firewall, rather than the neutral safety switch, which is on the left side of automatic transmissions. Out of curiosity, why do you believe that it needs to be serviced?

I changed the motor and transmission from one to the other .I went from and automatic to a 5 speed manual changed motor harness now the car will not start turn key and nothing new battiery can you give me...


If you swapped out the auto for a manual trans the car might have a neutral start safety switch preventing the starter from engaging. This would not be something you would have on a manual transmission. Instead the manual would have the Clutch Safety switch which will only allow the starter to engage if the clutch is pressed in. On an automatic it won't allow the engine to turn over unless it's in Park or Neutral. I would locate the plug for the neutral start safety switch for the old automatic transmission and bypass it.

Turn key on, but doesnt even click. battery and starter are fine


This may be due to a bad neutral safety switch, is this car automatic or manual transmission?

If automatic try to start in neutral and if manual try to locate switch on clutch pedal and use a jumper wire to jump connector for switch, NOTE; If switch is jumped car will start in gear with pedal not pushed down and car will take off so this is just as a test not a repair!!!!!, good day

I need to replace the neutral safety switch on a 1989 Jeep Comanche 5 speed manual transmission


I think you are referring to the clutch pedal safety switch. If so it is located behind the clutch pedal under the dash.

I have a 5 speed transmission and my clutch neutral safety switch is going out. can I bypass this switch


well to clear things up, its not a "neutral safety switch", manual vehicles have a clutch safety switch!
And yes you can bypass it, follow the clutch pedal up behind the dash, you'll find the switch. pull the plug and "short" the two connections(of the plug) with a piece of wire.

What makes you say it is "going" bad? Just curious, normally it'll just stop working!

88 s10 2.8 5 speed have power to lights, blower, radio, but wont turn over when turning key no clicking nothing wont even start or turn over by crossing solenoid


Since you have power to your accessories, here are a few more things to consider:
1: Automatic transmission not in park or the neutral safety switch is faulty
2: On manual transmissions clutch pedal not depressed or or clutch start switch failure
3: Broken or loose wires in the starting circuit. Inspect all wires and connectors at the battery, starter solenoid, and ignition switch
4: Starter motor pinion jammed in flywheel ring gear. Manual transmission. place transmission in gear and rock the vehicle to manually turn the engine. Remove starter and inspect pinion and flywheel

Just curious to know more about the clutch safety switch/ neutral safety switch for a 2003 GMC Sierra 2500HD with the zf-6 (6 spd manual) Mine is acting up, it doesn't want to crank the engine, unless I...


The way the clutch switch works not to be to simplistic is the vehicle will not crank unless you have the clutch pushed in. It may be that you need to replace the switch its not hard or expensive to do. You may also be able to adjust it The neutral safty switch is feed from the clutch switch thats the master control because if the vehicle is not running you realy woun't need the neutral safety switch. You have a 2003 this switch should last longer then that the clutch switch. So look up under the dash at the top of the clutch pedal you will see a switch attached to the top fof the pedal and it will have a plastic threaded rod with a adjustment nut to control when the switch is triped to the on pisition adjust this nut so that the switch is compressed sooner and activates the switch with less travel distance before it gets to the floor. You still may need a new switch it depends but its inexpensive and easy to replace and will likely correct this problem

2000 Pontiac Sunfire wont start


Its likely that you have either a bad ignition switch or a bad neutral safety switch (if stickshift, clutch switch) Try starting in neutral...if it starts, change neutral switch (jump across clutch switch, check starting in neutral with your foot on the brake) Ignition switch is on top of steering column under dash.
