Interesting.

I tried to start again and it will crank, sound like it will run but only while cranking.

I connected the HEI directly to the battery and WHAM! runs perfect!

Let me ask.... should the pink wire on the dash harness provide 12volts from the ignition, no matter whether the dash harness is one with lights or gauges? Even if it wasnt, shouldn't the yellow wire make up for any issues since it is run from the 'R' terminal on the starter to the HEI?
