fried coil pack/ecm?

I have a 91 Grand Voyager 3.3 and when in a drive thru i noticed erratic idle and sputtering like it ewas cutting out..
it idled poor and was giving me a code 43..coil pack..(it had a split in middle and wasnt firing there)
I tried to do a reset with disconnecting battery--a NEVER .no matter how long..the moment i put battery on and only tirned key to check codes-no start--that same code continued to remain..
I slowly got iy home and as giving gas an pulling close to street it went out--everything--and i was rolling on in driveway on gravity..
No Restart-just a turn over and NOW--NO CHECK ENGINE LIGHT at all...nor if i reset battery...no fuel pump kick in and likely no spark ..Alos--when u connect cable to battery that moment -i usually hear a Click--no more//

I changed the auto shutdown relay and still nothing...is there any other thing that it may have blown as engine shut off?

Did i fry the ecm? i have no way to get a 3 key turn code now..
I put new coil pack in it and still no start ..no check light and no longer that click -as i touch battery positive...nor fuel pump hum..


any ideas?
