I was driving my van and it lost power and died shortly afterwards. It restarted and I was able to drive it home. Since then it won't start. It turns over but won't start. I checked the fuses under the hood and the fuses inside the van. Everything seemed to be in good working order. So I got a new "main fuel relay switch", I plugged it in and there was no change when I tried to start it. So I thought it was my fuel pump since I couldn't hear it turning on when I would try to start the van. I replaced it. Still no change. I am about to change the fuel filter because I changed to fuel pump, but I don't have any hope that this will fix the problem. I have heard that it could also be an ignition switch or is it something else? Any help would be greatly appreciated!
