I have a 94 Ford f150 with the 5.0 V8 automatic with 4x4 duel tanks. My truck has no spark at times. When it does run it runs great. It has no spark after the vehicle sits for over three hours. I have already spent alot of money on this stupied truck. I have replaced plugs and wires, replaced the whole distrubutor(cap, rotor, etc. complete unit from oreillys). I have fuel pressure. So when it does not start I have pullied cap off and rotor is turning, I also have checked coil wire at distrubutor and there is no spark. I can tap or sensors and coil and nothing but after tring to start with complete on off ignition cycles the truck will start and run great someone please help I going crazy from this truck.

 

Looking at the wiring diagram it could be the Ignition control module. That is what controls the coil.

 

Where is the ignition control module?? On this truck im a Gm guy not use to Fords what does it look like

 

It could either be under the dash, or a kick panel. I would do a google image search or parts store.

 

ayuda! ayuda! ayuda!

 

have another for me.

 

ok thanks I will try to find it tomorrow
