I am still chasing down a hot no crank issue with my 1991. The new starter didn?t fix the issue. I decided to see if there was a grounding problem. I pulled the battery and found the thick negative that I think goes to the starter area. It has a splice block on it that definitely doesn?t look like it came from the factory. For context, below my hand is the battery tray. I took it apart and reseated it better than it was before. Does this thick wire in fact go to the starter? Could this be causing my issue? It didn?t feel loose, but I definitely got it seated better than it was. I?m not holding my breath, but I?d be ecstatic if for some reason this fixed it. Other info that might help is at idle the turn signals seem a bit slow and the voltage gauge moves up and down when they are on.
Edit: the splice block was on the POSITIVE side coming off the battery and then going down to the starter area. Last edited by Tim555; 05-24-2024 at 11:51 AM. |

Just got back from a drive. The hot start issue still exists.

Have you confirmed the ground/negative cable connection is good? ... not just looks good but tight and not corroded at the frame.

Specifically confirm proper ground of negative battery cable and any ground wire/cable/strap between engine and frame.
Perhaps your starter isn't getting sufficient ground source, so maybe try connecting a single jumper cable from an appropriate clean location on engine block to an appropriate clean location on frame (to create new/additional grounding)... if nothing yet, try jumper from engine block to negative battery terminal. Heat expansion can compromise connections. I am thinking ground issue as you stated turn signal operation affects voltage gauge.... check that alternator wiring is secure, too. If still not resolved, I recommend you check out the wiring to the starter solenoid.... unfortunately, it likely requires pulling plenum. Last edited by hotroddaddyo; 05-24-2024 at 11:50 PM. |

The battery needs to supply 12.5 volts or more when the hot no start condition is present. Check the battery voltage with the ignition off and the doors closed.
The clutch switch is a suspect. An easy way to move forward is to install a 12 gauge wire to bypass the switch. The clutch switch has two black wires in a black connector. The other side of the connector has purple and a yellow wires. Jumper the purple and yellow wires together. Drive the car and see if this makes a difference. |

The question is why is there this type of splice,is there an aftermarket stereo in the car?

Still didn?t get a chance to warm the car up and try connecting a jumper cable from the engine to the battery or frame to rule out an engine ground. Edit to add I did check the battery voltage with the car off and doors closed. It?s 12.5. It?s a new battery from the fall. I?ll have the local advance auto load test it. I?ve seen batteries before that seem good but fail a load test. That said, when it does start it cranks over pretty fast and it doesn?t sound like the battery is weak.

I may have bigger problems to deal with. When driving the car to warm it up it started making this noise. It happened abruptly during easy driving (off throttle, in town going down a hill at maybe 30mph). It sounds top end.
