Pls help!!! I am new.

I have a mint condition 86 EFI F150 302.
My voltage regulator went without me noticing the side affects. I blew a batt and lost all power on the highway. Smoke came out of my CD player!! It's back at my place. I have replaced the alternator(internal voltage regulator). Replaced the fuel pump relay. But still no power to the pumps unless I use a jump wire. I have a crank no start issue!!! What do u think I should do next? Also I have no spark? Is it the Ignition module? Coil? EEC? Computer?
Any pointers would be more than appreciated. I need to get the truck going ASAP !!!
Thanks

Check your fusible links near your starter solinoid. Make sure you have power first.

Yep I have power. With a test light on the coil plug wire, the light is quite dim and flickers. The coil is giving off about 10v w/ crank. Batt is almost 13 at rest. So a diff of almost 3v. Also the distributor cap had burn marks on each post so I got a new one. What do u think is up?

You need a higher voltage on crank for your coil. 10V would be a run voltage. Have you got a Duraspark module?

I have listings for both for that year. There is a resistor between pin 4 on the EEC and the negative of the coil. Also, there is a resistor wire between pin I1 and I2 at the ignition switch. Do you have a Ford EEC code reader? Have you checked the ground cable to the engine block? Give it a tightening or cleaning first before going further. Also check the starter solinoid on the fender for good connections and check voltages on terminal I, if it is used, and the terminal going to the starter while starting.

I cleaned the block ground really good when I first started working on it. And I will try the resistor and solenoid testing ASAP.
