i have a 1994 mustang cobra with a resent 306 engine. for some reason the car wont start at all any more. i was going down the road and it just shut down. now all it does is turn thats it. i have put in a fuel pump and fuel filter, i replaced the cap and rotor for my distributor, changed my spark plugs and wires, the ignition coil, i have fuel pressure and spark. i checked my fuses and they are all fine. can anyone tell me if i am missing something here?
