Test and repair advice for throttle body injectors.
What is your question?
I have a 5.7 in this truck and I have 12+ volts at the injectors on the throttle body yet no signal with a noid light connected when cranking the engine, I suspect there is a computer issue with relation to ground (short to ground) (Note, The oil pressure sending unit was shorted out causing the fuel pump to run with or without key and burned out fuel pump.)
How do I check the reference voltage for ground and power to the injectors? I appreciate your advice.

Not mentioned in the above link .. but is possible > TPS stuck in wide open throttle position triggering 'clear flood'.. Also CTS reading high.. Unhook both sensors, one at a time, to test.. Good luck!
