Wire/Solenoid Problem

Q: Wire/Solenoid Problem

After driving my 1968 on the highway when I pull into my neighborhood, the car starts to cut out a little. If I stop the car, many times it won’t start until it cools down, and when it does start, it runs very poorly, cuts out and dies. I started looking at the set up and the selenoid is very close to my headers. Also, the wire running to the selenoid is potentially touching the pipes. I plan on redoing the wire, but what else could it be. Is the selenoid just getting too hot and how about the poor running?

A: The wire and solenoid running too close to the exhaust will cause starting problems. However, after starting it should not affect the running characteristics of the motor unless you’ve burned through the wire insulation and it’s shorting out. I would check the positive battery very carefully. Also, check the negative cable and make sure it is making a solid connection to the motor. Also check the gas line and make sure it is not too close to the exhaust. You could be boiling the fuel and creating vapor lock.
