I shut the van off it was running perfectly when I shut it off at a gas station. Then it refused to start. It was as if there were no power. It made no noise at all. Someone told me it was the neutral safety switch, my husband jump the solenoid and got it to run so I could get it home. Got it home we replace the neutral safety switch still will not crank. Can’t even jump the solenoid. Everything else is working perfectly. All power functions are working, but it will not start it will not crank.

Welcome to 2CarPros.

Holly, when you say you can't jump it at the solenoid, are you referring to the starter itself? If that is the case, either you lost power to the starter (larger wire) direct from the battery or the starter is bad.

Here is how this works. You have 12v direct to the starter at all times (larger wire). Also, there is a smaller wire to the solenoid which only gets power when the key is in the start position. That is what actuates and engages the starter. If you do have power to the larger wire direct from the battery and you jump the starter at the solenoid, basically you are temporarily powering that smaller wire (you are doing it in place of the key). If the starter doesn't engage, it's bad.

Now, here is a link that explains how to test a starter. Basically, you are checking for power to the starter to confirm it isn't a connection issue. Take a look through this and let me know what you find:

If you find there is no power to the smaller wire when the key is in the start position, next I would suggest checking the starter relay. See picture 1.

Here is a link that shows how to test a relay:

Do this and let me know what you find. If you have questions or need help, let me know.

Take care,
Joe
