Hello, if it cranks good but won't start, have a helper crank it, while you check for spark at the plugs. If you have good spark everywhere, check fuel pressure. Start with the basics. If you do a lot of testing with the vehicle cranking, you may need to disable the fuel system.

I'd do some basic tests and see what it shows? No spark, no fuel, what?
