Howdy fellow Forders,
I have a 93 F-150, straight 6, 5 spd, 4x4...
Drove her a few days ago and ran fine...parked her for 2 days and went
to crank her up and all it does is turn over?
About 2 months ago I changed battery,plugs,plug wires,
distributor, cap an button,coil pack and had it all timed, she
purred like a kitten! But now it just turns over!
I checked the fuel...pump works,have pressure in the rail.
Checked the coil pack and it has no spark from it or to the plugs!
Bout a brand new one and still no spark! Checked all fueses and relays,all good.....if anybody can maybe through me some tricks my way please do so! And thanks.... "Happy Fording"

 

Probably the ignition control module. It's mounted either on the distributor or the fender. Could also be the pickup coil.
