Will not crank or start

Hi,

If all fuses and relays are good, we need to go to the starter motor and check for power. This will confirm if it is the starter or if we need to work back from that point to determine where the power is lost.

I attached the wiring schematic below for the starting circuit. Note there is a 40-amp fuse (fuse 30) in the under-hood fuse box. I realize you checked fuses, but also make sure there is power to and from it. Here is a link you may find helpful.

If that is good, switch the relay with a different relay in the box having the same part number.

If that doesn't make a difference, we need to check the power at the starter. You will need a helper for this.

At the starter, there are two wires. One is black and the other is purple. The black wire is a heavier gauge wire. It should have 12v at all times. Confirm that.

If that is good, the purple wire will have no power until the key is in the start position. Have the helper turn the key to the start position while you check for power at the purple wire.

Now, if the heavy gauge wire has 12v and the purple gets power with the key in the start position, the starter is the likely problem. However, check this and let me know what you find.

Take care,

See pics below. Note: The schematic was one page. I had to cut it in half to make it readable for you. I did overlap them. The last pic shows the under-hood fuse box. I highlighted the fuse and relay.

Has the starter ever engaged since this started? If it did, recheck the orientation of the pic and the box in the vehicle. Without that relay, it will never crank. Could someone have removed it?

As far as the switch, it could be bad and still have most of the electrical system working.

The starter relay can be jumped using a short jumper wire. You would need to jump terminal 87 and terminal 30 in the box. See pic below

Let me know.

It sounds like the starter is bad. If you jumped power at the relay directly to the starter trigger wire, it should have engaged.

Was there power at one of the terminals you used when you jumped at the relay?

Let me know that. Also, here is a link that explains how to replace a starter motor. At this point, I would remove the starter and have it bench tested at a parts store. They should do it free of charge.

Keep in mind, you must make sure the battery is disconnected before working on the starter.

Let me know what you find.

Take care,

See pic below. It shows the location of the starter motor.

Hi,

Remove the foil tape. Anything that is a conductor shouldn't be used, especially near the starter.

Pull the starter and have it bench tested. Just make sure to disconnect the battery before you start working on it.

Let me know what you find.

Hi,

Were you able to replace the starter with a new one and is it working properly?

Let me know.

Joe

I don't recall this one being too hard. It's at the front of the engine.

Regardless, let me know how things turn out for you or if I can help in any way.

Take care,

Joe
