I have a 2002 mustang GT. I am currently on my second 5.4. While switching motors i lost my keys. Had a locksmith come out and make me a new key with a chip. Motor is all hooked up , no fuses are blown, pats light comes on then off. Checked all fuses. They're good. I need help. Ive got no fire no fuel. Car does turn over but will not crank.
