If the sensor should go bad will it still blow the fuse.I even disconnect the both,and tried again and still blows. The wire you are talking about that's tied in with the pump what is the color. I don't even hear the pump when I turn it On. or Power at the Battery pin at the check connector. By the way will this problem also will cause No Spark at coil If you got more for me to know, please help I need to make this van operate so I can go get the kids something for christmas.
Once again Thank You very much and Merry Christmas

Tom, I'd try tracing the power wire from the fuel pump and then work my way back through the harness....
Have someone cycle the ignition while you check the main lead with a test light....
The EFI fuse wouldn't cause a no spark condition (that's the IGN fuse), so you might wanna check if the distributor has pulse as well....
