Re: I think fuel
What year? Some years have three fuel pumps with dual tanks, other have only two (one in each tank).
It sounds like your "changeover" valve is stuck. The pump(s) is/are working, but the valve is preventing it from flowing, or you have an electrical roblem (no spark etc). |

Re: I think fuel
If ModMech is right, you need to change your "changeover" valve {remember, your not actually looking for a valve, but the part that opens and closes it}. I need to ask, whats your ability on mechanics? Just from the post it sounds like little to none. If I offended you I apologize, but if you dont know what your doing, I strongly suggest you take it to a mechanic.
