so i had my car fired up last night, permanently wired up this time but fuel tank still by the side. for some reason i was getting intermittent spark under cranking but once it started it ran fine. had it shut down for about 10 minutes checking things, then all of a sudden it wouldn't crank or even click the solenoid. checked all the connections for the solenoid wiring, found that the farther down the circuit you get the lower the voltage drops. by the time it reaches the clutch switch it's only 5 volts. i have 10 volts at the ignition switch for that circuit, battery ocv is 12.6 and so is the main voltage at the ignition switch. tracing the starter solenoid circuit i found it also feeds the tfi module under cranking, and sends a crank signal to the computer, which would explain the intermittent spark/hard start condition.

i suspect the ignition switch took a shit at the starter terminal. anybody heard of this happening? thoughts?

seems fairly commojn on the newer cars for some reason

yeah, slap an Ignition Switch on it
 
i put a new switch on it and it still wouldn't crank, traced the entire circuit before i gave up and pulled the starter to test it. it tested fine, tested for voltage at the solenoid connector and randomly had 12 volts. put the starter back in and it fired right up. argh.

sounds like a bad connection and you found it
