I'm stumped on a fuel pump circuit problem! Need Ford Tech Answerer?

You might want to ask if there is a chip in the key depending on the modle it may have gone out, because if the chip is broken it won't allow for your viehical to start. We had one go out on ours and my husband thought it was the fuel pump and relay when all the time it was the chip. We have a chevy now just for that reason if you have a second key try it first before you waste any more money. I hope that helps.
