I have the vehicle listed above B250 van. No start, no crank. Dash lights light up but when I turn it to the start position nothing happens. No sound, no click, nothing. The wiring on the neutral safety switch connector were very brittle and stiff. I noticed that once of the wires had broken in half on the connector. I spliced the wiring together but still nothing. I'm wondering if I have the wiring correct. However, I did try all possible combinations which isn't many given there are only 3 wires on the connector. Any thoughts? Also, can you provide me a wiring diagram for the neutral safety switch connector.

If this is the case, then the switch may not be the issue. Here is a guide that will help with testing the switch:

However, if you are not getting any clicking then I would suggest we go to the starter relay and jump the relay to find out if the starter is working. If it is, then the starter is likely the issue.

Please see the wiring diagrams below for this system which will help with the testing laid out in the guide.

Let me know what questions you have.

Thanks
