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 clutch switch seems to work. When I turn the key with the clutch depressed the voltage (as indicated on the instrument cluster) drops. Without the clutch depressed, it rises slightly. Could the clutch switch or its associated circuitry be faulty and have a higher resistance than its supposed to even though it appears good? I did unplug it and tryjumpering the purple and yellow wires but this didnt seem to work. I?ll try with thicker wire since all The starting current has to pass through it. The next step is just to wire in a relay to send current directly from the battery to the starter. The process is described in this post for anyone else who?s having a similar problem

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.
