Hi,
I cannot start my F150 (1986, V8, 302). Where is located the electronics (computer) for the ignition system. I got a spark but not at all time. I checked the rotor, plugs, wires, etc.. all are ok. I thinking that I have a problem with the electronics. The truck has been sitting outside during the winter. (I got fuel coming to the injectors). Any ideas?
Thanks,

If you have injection... you must have the EEC ignition system.
There are three parts.. the dist pickup under the rotor, the TFI ignition module mounted on the side of dist, and the coil.
AT the age of this truck, any of the three could be bad.
I would START with the ign module... there is a special tool to remove it, or you can grind down the barrel of a 7/32 (1/4 inch drive) socket.
If the grease is hard and caky, the TFI is probably the problem.. take it to autoparts store and have it tested if it's still greasy.
Next likely is the coil.. these also have a lifespan and cant hurt to replace, esp if it's got a lot of dirt buildup between the frame and the barrel.... likely cracked.
LAst is the pickup coil.
Ok, I replaced the TFI, the coil, and the pickup coil. Still no spark. Any idea? Thanks,
electronics
