Have Ford Questions? Ask a Mechanic for Answers ASAP
Does it flash fast when you try to start the vehicle?
If the light does not flash rapidly when you try to start it, the problem is not with the security system. Does the engine crank over by the starter when you turn the key or does it not turn over when you turn the key?
Do you have a test light or meter to do a few electrical test on the starting system? I'll be on line the rest of the afternoon today.
