Crank no start

Hi,

What I'm hearing is a weak battery. It may have failed from sitting through winter. Here is what I suggest. Follow this simple guide for load testing the battery at home, or remove the battery, charge it, and have it load tested at a parts store.

If the battery is too weak, it won't start. They need to be able to maintain a minimum of 9.6v while cranking for the ignition system to work properly.

Let me know what you find. I'm interested in knowing.

Take care,

Hi,

I did hear it. It sounds like the starter Bendix is bad and allowing the starter to disengage from the flywheel while the starter is still turning. Have you removed and inspected the starter and gears on both the starter and flywheel?

I attached the directions below for removal. Let me know.

Hi,

Sounds like a plan. Please understand that I am hearing this on a computer, so it may not sound the same in person. However, it sounds like a starter issue.

I will watch for your reply.

Take care,

Hi,

The starter engagement happens at the same time as the starter motor gets power. Both are triggered by the same power supply and wire. So, if you hear it free spin, which tells me the motor still has power, and the Bendix should still be engaged (it has no choice).

In this case, if the Bendix drops out and the motor continues, it isn't a wiring issue within the vehicle. Instead, the Bendix is likely bad and disengaging when it shouldn't.

You could remove it and have it bench tested at a parts store. However, based on what I hear and what you describe, it needs to be replaced.

If you look at the attached pic below (sorry it's so sloppy), I attached the wiring at the starter solenoid (Bendix) and starter motor.

Note there is a black wire. That wire is a heavy gauge wire direct from the battery. It has 12v at all times. The smaller purple wire is the "Trigger" wire. It will receive 12v only when the key is in the start position.

When the purple gets power, it engages both the Bendix and the starter motor. So, if one has power, they both do.

I hope that makes sense. Note: I put a K+ on the one that only gets power with the key in the start position.

Pics 2 and 3 are the entire circuit. I circled the battery in pic 2 and showed how it goes to the B terminal on the starter. And purple goes to the S terminal.

Let me know if this helps or if you have other questions. Also, if you replace it, let me know if that takes care of the issue.

Take care,

Joe

See pics below.

Hi,

If it passed the bench test, try switching the starter relay with a different one having the same part number. Maybe the relay is failing.

As far as the pics, they look normal. There is a little wear, but nothing to worry about. Is there any difference since the starter was reinstalled?
