What could be wrong with my van?

Question

While I was driving my van started to putter and dropped speed fast. It shut doun completley. I thought it was the fuel pump because I couldnt hear it click on so I replaced it. the van still wont start. So I replaced the coil... Still nothing. Over the past few months or so the van started acting weird. The oil light peeps and stays on even after an oil change, the horn stopped working and the fuel gage would go from full to empty over and over again while driving all the time. What could thes problem be? Money is tight and I fix it myself. Could this be the fuel pump wire harness? If so where is that located?

Answer 1

i dont think the fuel pump harness would effect the oil light. What year van model and engine size?
