Default working on a 200 HPDI for a friend, have a question
Friend has a 200 HPDI small block. Cranks but doesn't start, it has spark, good pressure from the VST and is reading about 650-680 on the HPFP when cranking. Also has 135psi on the cylinders. No codes for open fuel inejector or anything like that. So I assumes the injector drivers are good.

I always thought the HPFP pressure should be closer to 1000.

Any thoughts. I am about to spray some fuel down into the throttle bodies to confirm the engine is too lean to start.
