Help needed please! My 1998 4.7L GT (22,000 miles) cranks but won't start. This is a sudden occurrance. I drove the Mustang into the garage, left town for a long trip, and returned to find a truly dead battery. I replaced the battery with a new one from Ford. The engine cranks and cranks but I don't get any ignition. I've gone through the disarm sequence for the factory anti-theft, and done the same dance with my aftermarket Clifford Avantguard III alarm. I've also checked the fuel pump inertial reset switch but it seems fine. The fuel pump 20 amp fuse looks okay. How can I tell if the fuel pump or relay are operating? Could my fuel filter be clogged? (Where is the fuel filter?)
For the life of me, I don't know what to do. I'm out of ideas and I hate the thought of getting a tow to a dealer. I'll be vastly grateful if anyone can guide me to a solution.
Many Thanks,
