Had the 5.0 s/c in to the dealer for an aircon leak repair. Whilst in, after they'd had it for a couple of days, they advised me that the fuel pump electrical unit had failed and they couldn't start the car. They fixed it and the aircon, both under extended warranty and returned the car to me today. All well...

Got home, put the IID Tool on to check and a fault came up. There were no faults before I took it in.

P0232-24(28 Fuel pump A - Secondary circuit high - General signal failure - signal stays high

Tried to clear it and restarted and the fault showed up again. It says MIL light activated but there are no warning lights on the dash. The fault won't clear. It says signal stays high which implies pump continuously running. I can't hear it running.

I've driven only about 10 miles since leaving the dealer. Is this something that will clear when the pump has been running for a while or do I need to take it back?  2012 5.0L S/C
