Car Won't Start When Hot: Starter Doesn't Turn - Not The Starter
I posted this thread a while ago: Car Won't Start When Hot: Starter Doesn't Turn. I have since replaced the starter. It was not the starter.
The problem has now gotten much worse. More often than not, the car won't start. I have discovered that placing the ignition key in the on position and running positive power from the battery to the starter (solenoid) will start the car. So, I think it comes down to one of three things: wiring, ignition switch, and the neutral safety switch in the transmission. I am pointing my finger at the neutral safety switch (NSS). Which wires connect to the NSS? That is, laying no the ground, looking at the transmission, how do I identify the NSS? TIA |

its on the side of the transmission...looks like this
[IMG]http://www.***************/secure/PartImages/0005454906.jpg[/IMG] I had mine break a while ago...the car wouldnt start...yet if i put the key in..turned it on...popped the hood and jumpered the start it would start... that sounds like your culprit..i believe its on the driver's side of the trans...the shifter linkage runs though it.... to remove...rotate white clip..pull plug...remove linkage from nss...unmount nss..and there u go hope this helps kris

Crawling around underneath, neutral safety and reverse lights combo switch will be the electrical hookup on driver's side. Degreasing, unplugging and replugging it might help. Also try working the tranny through the gears, sometimes the car might start in N but not P. And try wiggling the shifter in P or N while turning the key.
The fact that this problem has gradually gotten worse instead of just suddenly dying could indicate slow mechanical failure of the NS switch, i agree with you that's probly the place to start. And turning the key makes electrics come on and glow plugs heat up, correct? This should indicate the key switch is okay. |

You need a "HARD START" relay. With the car being 28 years young, the wiring, ignition switch gets resistance and/or poor contacts. The relay takes the load off of the ignition switch. Try the NSS but if it still doesn't start hot, let me know. The relay is easy to do and total cost is about $20-$25. Chris

How's your ground? There's a huge but short ground strap that goes from under the head of the screw that holds on the starter to a solid point on the body. Without this strap clean and tight, all other efforts will be largely futile.

However, if it were the ground, I doubt it would start when jumpered. |

OK, then how about the cable to the starter? You've probably checked this too, but I've had several difficult to find electrical problems in my wrenching days, and more often than not, there was a failure somewhere in a large cable that I had checked several times, but not carefully enough.

Update
I believe it was the connection to the NSS. After replacing the NSS I suddenly had reverse lights, but still no start. So, I took the connector off and carefully examined it. One of the female connections was WAY too sloppy. I tightened it down with some pliers and now everything is back to normal AND I have reverse lights!

Try starting it after pulling the brown vacuum line off the shut down switch on the rear of the IP, that would eliminate the ignition switch.
