Corrosion at the fuel tank to body harness may cause the Check Engine Light to illuminate or a crank no start condition. This corrosion issue is most commonly caused by a water leak inside the vehicle. Any damaged wiring or connectors will require replacement.

main wire harness runs under driver's seat and plugs into the floor in front of rear seat. The connection inside the van and underneath connectors are corroded. THERE IS A SMALL PLATE COVERING THE INSIDE CONNECIION. This is an easy removal. simply drill out two rivets and the plate comes off. Finding a non-corroded connection in a junk yard is difficult.
