All,
I have a stock LS2 (2005 GTO) except for a decent sized street NA cam. Car ran great until I recently made the following mods: Holley Lo-ram intake, Nick Williams 103mm TB, 3 bar MAP sensor (only one available at the time to work with new intake), and 42lb Holley injectors.
Car ran for about 5 seconds on initial fire up after the mods were made. No abnormal mechanical sounds to indicate mechanical failure. Car just continues to spin without trying to fire. Here is what I have done so far:
Replaced cam sensor
Replaced crank sensor
Confirmed I have spark and fuel pressure
Set Flow Rate vs Pressure table to 42lb injectors (just to get them in the ballpark...down and dirty)
Set ETC Area Scalar to 7298 (pi x 51.5 x 51.5) - (103 x 10) = 7298
Set MAP Sensor Linear to 305
Let me know where else I should be looking to get this thing to fire.
