i beleve the problem could be a bad
fuse #1
fuse#10 located in the engine compartment
(shorting buss conector#3) i beleve it is located in the under hood fuse box, if this failed there would be no ground for the ignition relay,you can test for a bad ground by removeing the ignition relay r16(located under the dash) and testing for resistance where pin #1 of the relay goes in.
if ground is bad replace shorting buss conector#3 if you cant find it ford will tell were it is located
if the ground is good then check for 12volts were pin #2 on the relay goes in with the key in the run position.
if 12volts are presant use a jumper wire between where
pin #5 and #3 on the relay go in.
try to start if starts

replace the ignition relay
if not post back
