I installed a different head on my 85 Charger this weekend. I started it and got it running. Then I shut it down to install all of the intercooler tubing and when I finished that it wouldn't start. WTH? I checked for codes and got #53 internal check failed. OK, so I put a different chip in the logic module, no start. So I changed to a different logic module, no start, checked for codes and found #26 and #27 injector drivers. I changed the power module and got the same no start. I checked continuity on the grn/blk wire to the coil, its good. I checked cavity 10 fuse, good and the fuel pump comes on, what am I missing? Any one had this problem before?
