Here are some links that might help.
If the ICP doesn't reach >500psi, the injectors won't fire.
We were driving on I-80 and suddenly lost all engine power (like the engine turned off).
We rolled to a stop and checked Utube for help.
We had recently installed a Edge CTS2 (
now a CTS3) to replace the scanguage and that allowed us to DIY that the hi-pressure oil system was broken.
Got towed home and spent some money to fix the issue.
What was on the repair list for the "bulletproofing?" STC fitting? dummy plugs?

Usually, in order for the engine to start, with your scan tool, you look for (cranking values):
cam/crank sync (sync=1)
FICM sync (the FICM is the Fuel Injection Control Module) (sync=1)
Commanded fuel pulse width, FPW (to ensure that the fueling command is given)
ICP pressure of 500 psig minimum
Cranking speed of 150 rpm minimum (PC/ED says 100 rpm, but functionally it is 150)
Acceptable system voltage (typically over 10.5 volts)
FICM Main power (MPower) of 46-49 volts
FICM logic power (LPower) voltage of over 10.5 volts, and
v-reference voltage (5 volts +/- .5)
