Car starts up then dies after the rpms just drop and only way you can catch them is putting the gas in all the way anything less and nothing happens, anyone have any solutions, everything on the motor has been replaced everything is basically brand new ,wiring, fuses, relays.

We need more info. Mods, codes, etc.

What is your HPFP pressure at idle? What are your AFRs? Fuel trims?

Try getting a lot before it dies and we can try to narrow it down.
