i swaped a 2008 ly5 engine and tranny and ECM from the same pic up into a older pic up i flashed the ecm with my vcm suite software and managed to turn engine on ! it will spark up and stay on for 3 seconds and shuts off ... any ideas as to what else needs to be done to the swap or ecm to make this work im losing hair and turning gray by the minute ........ thanks in advance ( fairly new to hp tuner software ) baby steps with it !!!!!
Have you disabled 2 Vats/starter checks and the corresponding dtcs?
Posting your file will help.
disabled vats and starter dont know the steps for the dtcs? would like ur help (baby steps with software) i trying to up load file
heres the file sorry i took so long new to this whole awsome forum world
Try setting P1631 to 3 no error reported and go to system and disable starter diag and report back.
does it need a write entire for this
No, it should not.Quote:

Next step is more Diagnosis.
Check to see what is missing/cutting out.
Fuel pressure or Spark or Injector pulse. (or a combination)
Also log all Vats ifno to see if it is going into theft mode.
the injector pulse dies out
Add the " current firing cylinder " to your scanner. If it never moves your crank sensor failed , I had this issue when I swapped an lq9 into my 96 like 6 years ago.
When I installed a 08 PCM on my 07 truck it would turn on and die, I had to disable VATS, P0513 and P0633 because the key dont match the PCMQuote:

You must do a write entire when making changes to the VATS or starter checks.
