HI,

Try the fuel pressure regulator as this is for as it says system pressure and differential pressure with the metering unit,
try and make sure you have no airlocks in the system, take the return pipe off the
regulator leading back to the tank, and bypass the fuel injection relay by removing
the relay and by bridging pins 30 and 87 at the relay the fuel pump will run continuously may need ignition on, and run the system for about a minute
if you can fit a pipe into the return port of the regulator put it into a bottle or
what ever and do a delivery check, and with a stop watch get someone to start the
fuel pump and get them to stop it at 1min, you should have minimun delivery of
fuel of 1100cc, or 1/2 of that at 30sec's on stop watch, if not fault could be volts
to pump should be 11.5v minimun with pump running,fuel filter dirty,or filter in metering unit blocked,
any other checks need fuel pressure kit to check out system properly.
also make sure the return to the tank is not blocked or the pipe kinked
