Just don't see why it stopped so suddenly as the relay was replaced a few months before and the pump primed no probs before the engine blew.
A new bigger fuel pump wont give you higher fuel pressure as its controled by the metering unit. You would need to mess with the fuel pressure elsewhere to get more fuel. NOT ADVISED
A std ERST fuel pump can run 300bhp why need more?
Putting a socket on the flap of the metering unit will flood the engine and it will never start.
You need to get it to someone with experiance of MFi without all the bukllsh1t or guessing and net waffle....
