Hey guys my Taurus started giving me some problems that it wouldn't start on certain positions now it doesn't start at all. Im guessing it's the neutral switch take your guesses please.

It's a 3.0 vulcan LX. 1986.

Cheers!

Considering how sensitive later model Tauruses are to battery voltage, I wonder if the same applies here. What kind of readings does your battery have right now?

You can also check the switch and it's alignment.

Hold brakes, put car in low or (1) and try to start. Repeat for each position going up. Car should only start in (P) or (N). If it starts anywhere else, switch needs service. You can also jump the battery lead to the small terminal and see if it starts.

Solenoid could have failed. Pull small wire and check for voltage when turned to start.

Nice thing about an old Ford...screwdriver across the big terminals will start it. Don't be afraid of the sparks.

It was nice of them to put the solenoid right on the fender. Pitty they took it away, and placed it on the starter motor.

Hey guys thanks for all the feedback! Tried to do the alignment thing on the neutral switch by getting it on Neutral position and inserting a clip on the little hole while adjusting the position but that didn't work out.

What happens if I try to start the car on L or D and it does crank? Will it damage the gearbox? I've always wondered what can happen because I was tempted to do that but scared it would give me some costly problems.

I was looking for the starter motor but couldn't find it easily (had bad lighting at the time) but I recall it was on the firewall side of the engine...So just jumping the two big connectors should start the car?

And by the small terminal you mean the one on the starter relay thing on the fender or on the starter itself?

Sorry for all questions and thanks for all the help including the youtube help

If you have your foot firmly on the brake, nothing should happen other than a little lurch.

Thanks man! It's the only automatic I've ever had so no experience on those sort of things.

Starter is hanging out front and center, right behind radiator, next to oil filter. The relay for testing is on the driver's fender, the small terminal is on top of the relay. There is no small wire going to the starter, just the big one from the relay.

BTW just wanna say thanks to all of you the problem is the neutral safety switch, following your recommendations what I did was to jump the upper terminal with the positive side of the battery and the starter cranked. Later I checked on the service manual and it said that if it did crank then my neutral switch was damaged.

I managed to start the engine this way and give it a spin! Was real nice only very WEIRD thing was that when I disconnected the small terminal i got the SPEED message on the electronic cluster and it wouldn't go away until I connected back the cable.
