I have a 94 Safari 4.3L AWD 150,000 miles. She quit and won't restart. Fuel pump is not pumping. I had trouble previously with Fusible Link A behind the battery on the firewall. The plug kept burning out and melting only on A. The headlights would not work, nor would it start. I replaced it 3 times with used plugs. When I finally bought a new one from the dealership, this seemed to correct the issue. The new plug was made of thick rubber, the old of plastic. This is a loaded Safari Cobra Edition with every imaginable electric extra. The previous owner had by-passed Fusible Link D and put in its place its own fuse box for similar reasons. After the repair, the van on occasion would act similar to what it was doing previously. Engine would cut out and headlights go out, but restart easily. I noticed most of the time it did it when I turned the headlights on. Now it won't start at all. I checked the plug and all of the Fusible Links. All is good. The headlights are working. All fuses look good. Any advice? Going through a divorce with 2 children and can't afford a mechanic!
Have you tried the fueld pump relay? Check this first, usually around the fuse box.

Yes, just changed it yesterday. Not the problem. I also tested the whole electrical system for power with a tester. Everything is getting power except the fuel pump. There is power going to the relay and leaving the relay. The wires from the relay lead to the fuel pump. They run behind the motor passenger side then under the firewall and beneath the van where they eventually connect to the fuel pump. Where could the power failure be? On the top of the motor, there is power. Under the van there is no power. Additionally, when I was testing the relay wires, there were 4 wires. 2 red, 1 gray, 1 green. Both reds were hot. When I touched the green, you could hear the relay click. Really makes no sense to me. What do you think?
