DF 140 BG fuel pump

Hello,
on a pair of Suzuki Df 140 BG the HP pumps run constantly as soon as I switch on the ignition.
On the old Df 140 they stopped after 3 seconds.
Pb or normal.
THANK YOU

I don’t think it’s normal, should shut off after 3 seconds. I’m pretty sure the ECM is programmed at 3 seconds. Would be worth a call to your dealer to confirm.

It's not the HP pump, I activated it manually, you can barely hear it, what's this hissing sound on DF140 BG as soon as you switch on the ignition?
