In my never ending quest to figure out the culprit of my random hard starts, I'm hoping I discovered something today.
This morning I was troubleshooting the overcharging problem I was having. It turned out to be the alternator I purchased a couple months ago. I finished my final checks, buttoned things up and shut the motor off. Came out 1/2 hour later to go to work and she just cranked. It had fired up several times earlier with no problem.
This has happened randomly for the last couple months whether engine was warm or not. The kicker is, it will start if I jumper the starter with a screwdriver.
I decided the next time this happened, I would read voltage at the power wire at coil and at the "S" terminal on starter with engine cranking. I had 12.1 volts at coil and only 9.9 at the purple ignition wire at starter.
Am I on to something here? Should there be 12+ volts at the "S" terminal?
By the way, I've switched over to HEI last May and didn't have any start problems until a couple months ago.
