Question about 1985 Ford F150
I have a ford with a 300 6cyl that starts but quites when you let go of the starter switch. It has a new started relay and I piggy backed a new ignition module - no help. With the ignition switch on Its got 12v mesured at the primary of the coil and you can see it ark when you take the wire off. a speharIf you jump. If you jumper 12v directly from the battery lug of the starter relay to the primary of the coil (or to the small terminal of the starter relay closest to the battery lug) it starts and runs fine, but of course you cant turn it off wuth the ignition switch. I also jumpered 12v directly to the ignition side of the ignition switch and it was no help also. Any ideas?
With the ignition turned on, measure the voltage on the coil + terminal, it should be 8 to 12 volts, if there is nothing or very low ( ie 2 - 3 volts) then I would suspect the ballast resistor, )which may be part of the wiring from the key switch to the ignitionpack or coil.)
