We took the car out for a ride today and she did fine until 40 minutes later. Just started acting like it was starving for gas then stopped running altogether.
Let it sit a few minutes thinking maybe vapor lock. Started and headed for home. Made it 2 miles and the same thing happened...just starving for fuel...then dies. Now when I turn the key on there is no sound of the fuel pump. Usually make a little humming noise. This car had sat for nearly 8 years before I bought it. Possible bad fuel pump? What would you think? Thanks |

Is your relay board in good shape? Any cracks in the tar on the bottom side? What about the relays on the board? Did you switch the fuel pump relay to a known to be good one? One of the headlight relays will do. (IMG:style_emoticons/default/idea.gif) |

I haven't looked inside of the box yet. Rain coming for 2 days so will have to wait to do that. Is it possibly the fuel pump has gone bad after sitting for so many years? |
