How much fuel in the tank? Does your scan device live stream engine pid's? Fuel pressure test may help also. There's a simple method in the tech section that uses the fuel bowl drain as a temporary test port. Need about 40# for proper injection.

May I suggest you take a few moments and work through the "no start flow charts" below which were taken from the 7.3L PSD Tech Folder.

And the actual code.
The mystery injector that had the high to low open, how did it sound on the buzz test?
Does the Wait to Start light come on like normal?
