Hijacking this thread. Sorry, I didnt want to start a new thread and clutter the forum.

M600!
Is there something I am missing , when I turn my key it no longer primes the pump and starts to dump fuel to the rail after a new file is created. wiring is exactly the same as the old tune, nothing has changed, it still is activated thru an AUX function and output test proved that the pump is working really well.

problem is simple, no fuel in the rails, then the car wont start! so what do i not know?

If you need and want help,
you should really start a new thread, as the topic is different.
That's how forums work.

What are your parameters for the Fuel Pump Function (i.e. Adjust->Auxiliary Output Functions->Aux Out 4 - Fuel Pump->Parameters)?

Seems like you need to have a non-zero number for Delay (say 2-5 seconds), and the Polarity & Output Mode need to be correct. Test by resetting the ECU to confirm the fuel pump runs for "Delay" amount of time.

You can test the Aux4 Output to determine which polarity is correct using Utilities->Test Outputs...
