No fuel... no go....
If the return hose is dry, you probably are not getting a proper fuel
supply to the rail. If there is fuel coming to the rail (pull one of the
hoses and check), then the problem may be with the fitting of the
pulsation damper (assuming that you have one).

The pulsation damper looks much like the FPR, but without a vacuum
hose. It attaches at the front of the fuel rail, on top of the banjo fitting
that brings fuel into the rail. Above and below the banjo fitting are
copper washers. One of them (the top one) is a thin washer with "teeth"
on the inside diameter. If this has been replaced by a plain washer
that is a close fit on the bolt, it can severely restrict the flow of fuel
into the rail.

If you don't have a pulsation damper, check for a blocked fuel filter,
kinked hose or flattened hard line. Disconnect the hoses one at a time
working away from the fuel tank, until you find the point where you
lose flow/pressure.

Cheers... jondee86

PS: Going down the shed to check some of this stuff now Tongue
