Not sure if this is the proper location for this, so I'd like to apologize ahead of time if it is not.
I have a 2012 Chevy Cruze 1.4L Turbo, ECO model. I just got the motor back in the car, replaced the headgasket, shipped the head out to be machined, all that jazz. I used the recommended timing kit for setting the timing on this motor, and I'm 99% sure it's fine, nothing hits or binds up, and she ran for about 15 seconds. I have been unable to get it to run after that though. Using Torque pro, I was able to lookup my "Commanded Air:Fuel ratio" which was coming back at about 6:1, way to rich. Spark plugs are soaked, confirming this. My question is, where should I start poking around next? I noticed that my MAF shows no airflow reading while cranking over the engine, not sure if this is what is throwing off all the calculations, causing the A:F to become so rich? I also noticed that it reports throttle body position, when not cranking, just sitting on, is about 30%, is this too wide? Is this what's causing the car to believe that it's getting more air, so it's adding more fuel to attempt to compensate for this? I haven't noticed the commanded A:F change at all while cranking over either.
Any input would be greatly appreciated, and I thank you for taking your time to read this, and possibly helping me out.
