Elec woes, crank, no start after running then parked.

So to sum up,
replaced BR with new RU11, no change.
replaced unknown coil with used but fairly new Blue Streak UC12 no change.
replaced LX101 ECU with used Mopar 4120505, no change.
Tap test at dist connector gives spark
jumper wire on ballast connecting each side, no change
test light from coil +ve to gnd, theres power.
The blue connector on back of ALT(squareback) is somewhat "loose". Wire is on snug, bolt is snug? The terminal on the alt itself is somewhat "loose"
