Can anyone take a look at this no start for me. Basically a shop swapped a Gen 4 5.3 into a 2010 6.2 truck and a guy brought it in with a no start. Here is a log and the tune from it trying to crank. Injectors on the rail look to be the gm 36# flex fuel injectors. The truck came in pretty hacked up so just trying to see if anyone sees anything obvious on the log or tune. Thank you

Did you try starting fluid? Check fuel pressure or spark? Check a plug to see if it's wet?
All of this and make sure plugs aren’t fouledQuote:

It's got no MAP sensor data in that log. Also is throwing a P0107 code too.
Vats?
Make sure map is reading atmosphere with key on engine off… unless high altitude, should be roughly 100kpa!! If it’s already 0-10 you have no map signal
