Neutral Safety Switch ??
My 1994 automatic F150 XL sometimes does not start.
On these occasions, I move the shift lever through all the gears once or twice and then it starts. Recently, it does not start at all even with the movement of the shift lever. When not starting, I turn the key and hear a click coming from the dash that appears to be the the ignition switch circuit closing.
Here's what I know:
1.) Starter is brand new (I put a new one in thinking initially, that it was the cause.). Pos (e-motor), Pos (solenoid) and Neg leads excellent contact.
2.) I understand that there is a neutral safety switch located under the dash attached to the steering column (however, when I look under there I have no idea which wires go to what).
3.) The wiring diagram involves the Key Cylinder, Ignition Switch, Column-Shift-Actuated Neutral Safety Switch, Relay, Starter Unit. (see attachment). The diagram seems to imply that the NSS is at the Transmission housing.
My guess is that it's the NSS. Maybe corrosion or malfunction. I wouldn't mind bypassing it if that's the case. Otherwise it could be the relay. I don't know where that's located or how to check if it's burnt out.
Would someone please help me out here? Thanks in advance.
