sounds like a fuel problem. could be a fuel shut off switch, fuel pump relay, fuel pump. Possible bad electrical plug connection to pump

It might be your fuel filter. Also, Dodge and Chrysler is bad for fuel pump failures. A clogged fuel filter can cause this. Also, you might not be getting enough fuel pressure. There should be a test port on the van, where you can test the gas pressure. You also have a fuel pump relay or switch. This could be bad as well. Hope this helps you.

Donna,it does not have a carburetor,and no gas to be used up,but the fuel pump is under the hood in the relay box,I believe on the drivers side.

Check your battery connections, and your grounds for loose connections. This will cause the system to go haywire.

try replacing the fuel pump relay. if that doesnt do it the fuel pump is bad.

Did you consider putting gas in it?
Did you chek the fuel pump if it works?
