Ya ya, Reverse started with wrong jumper cables on the wrong polarity and now my SR and now it will not turn over. Blew 75 amp ALT fuse. Replaced that and still not turning over. I can hear fuel pump turn on. Ran ECU diagnostics and it gave me fault code 21 - Ignition Signal and 34 - Knock Sensor. I did not have an analog multimeter to check igniter chip but with digital none of the pins had continuity. I will be heading to where the car is stored this week and wanted have a better plan of attack and better utilize diagnosing this eff up. Any help or advise would be much appreciated.

Thank you,

KC
