Van won't start, If I jump the silenoid connections at the starter it starts. But with the key I get no response, no sounds at all except that you can hear the fuel pump working. Everythings seems to work at the ignitions switch except that it wont start. Had starter tested, said it worked fine. What else could it be? Did have a check engine light come on a few weeks previous but I dont know if its related or not. Happened a couple of days ago but with a few trys it started fine.

Welcome to the forum, I'd check the circuits at the starter relay, in power distribution center, under the hood. Voltage to the load side of relay is hot all the time. Voltage to the coil side of relay goes hot with the key in start position. Use a testlite.

Tried to test starter relay switch but couldn't get reading from either side. I probed around with the tester I have (dont have a testlite) and didn't get a reading. I did make sure the tester worked before and after also. Could be my lack of skill but I tried every way posible to get a reading.

P.S. I did check the fuses. Wonder if it could be a fusable link or nutrual position switch?

Red wire is hot all the time. Yellow wire goes hot with key in the start position, it is wired through the neutral switch. Purple wire carries voltage to starter solenoid when relay is energized. Diagram shows load side of relay in non-energized position.

Found the problem. The purple wire going to the starter solenoid was broken. I bought the online manual and followed the step by step process and found it.

Thanks for the help, really appreciate it.
