The FPR was replaced by a MAS unit that control multiple functions (including fuel pump relay).

Can you hear the fuel pump buzzing when you turn key to position right before starting?
Cannot hear the fuel pump with ignition on. Cannot find a FP relay.
Behind the battery is the OVP relay, MAS unit and what look to be 2 x control modules - each with a large connector on top.

The crank position sensor reads ~1100 ohms, so assume this is OK.
