Good morning, I?m new to tuning. I had to put a new ECM into my swapped 5.3 GEN four, and I pretty much put the exact tune page for page on the new ECM that was on my old one that became corrupt from a previous tuner, the corrupt file was identified by another member on this forum gratefully, so it was a copy page per page, except for the corrupt file. I have no spark at the plugs can anyone take a look at my file and see what might be causing this? Also, I connected the old ecm and the engine will start and run for a second and shut off, so I don?t think it?s an issue on the mechanical side. Thank you.
