      LT4 swap into a 1972 camaro

      long time member - not a big poster. cant believe ill be the first on the ltx forum, i appreciate everyones suggestions.

      so i bought a crate lt4 motor from GM and the ecu kit (the one w/ the pedal etc)

      everything is installed, all wires are connected, primed the motor, new battery, and grounds separated, have fuel pressure, and oil pressure,
      engine will crank but not turn over
      when i turn the key to one click the red LED light on the 'fuse box' blinks...and when i turn to start it shuts off.

      hooked up to a scanner
      no spark
      no injector pulse



      cant seem to figure out whats going on. anyone that has any suggestions im open to anything at this point. i realize this has a lot of technical specifications and questions, even if someone would have a number to call or contact info on more in depth trouble shooting it would be great. i reached out to GM performance and went thru their suggestions and didn't get any closer.

      thanks in advance.
