Fuel Pump Prime Time

Recommended Posts

Hey is there a parameter that you can change to make the time to prime the fuel system when you cycle the key on?

I’ve changed :-

auF13397 from 1 to 0

auF10279 from 3 to 10 seconds

auF0356 from 8 to 12 seconds

auF1930 from 5 to 3 seconds

Still have seen no change from the 1.5 seconds the pumps prime for.

Anyone have any other ideas?

Yes i have the same issue as i run a twin pump system in the tank and it would be nice to prime it longer i have a feeling the setting cannot be changed as i have tried correcting this to 60 sec still no change i was thinking of putting in a trigger timer to bypass it

I've confirmed it uses a hard coded constant of 2 seconds for the timer. You would need to user a timer relay with a TOFF delay to extend the prime timer.

The other values are used for plant priming when the odo is < 100km or you demand a fuel pump test from IDS.
