ok i got a 81 fox mustang 99.5% drag style aut trans. 87 5.0 but when u turn the key i get nothing and when i jump the started wit direct power i get a humm from the starter not the cyloned dont have a clue what the problem is replace the cyloned still nothing Help me please!!!!!!!! any suggestions accepted e-mail Phildogracer@aol.com  

Do you by chance have a 140 amp alt.? I had the same problem with my 91 GT always running out of power if not ran daily. My problem was a diode which keeps power from shooting to the coil with the power and key turned off. If you have an ohm meter search the lines with the car off to see if you can find power in the charging circuit which is constantly draing power.Have you taken off the starter and taken it to advance auto parts to see if the starter is bad?  

help   i have a 1993gt ihave no spark at the coil.  i have replaced the coil still no spark can you tell me where this diode is located. Any help is appreciated  thanks.  

most modern alternators have the diodes built in ,they can however still be replaced though so check the wires first then take your alt to AZ and have it checked  

THANKS,  I HAVE INSTALLED A NEW ALTERNATOR,BATTERY, NEW SPARK PLUGS, CAP, ROTOR, COIL AND A NEW IGNITION MODULE.      The car cranks ok just will not start at all anything i am over looking?   i also bought a code reader and my egr sensor has a low voltage. trying to fix the car myself instead of having it towed to the nearest dealer for costly repairs  

are you getting fuel check if your fuel pump is cycling on  

maybe a ground wire not hooked up to complete the circuit.  

I had a problem with a 95 gt that wa kind of doing the same thing. I replaced the distributor and worked just fine.  

I would check the distributor pick-up coil 1st. They're known to go bad. It's inside the distributor, under the rotor.
