Do you have pressure at the rail when cranking? If not, is there power to the fuel tank pump - meter it at the pump/tank top.

No fuel at the rail and it sounds like it mite be the pump or the wiring to the pump

Check if you are getting voltage at the pump.First of all check the plug
behind the rear springs.If it is the pump try and get a genuine one
I got one off ebay last year and it didn't last long.

I have now took the tank out and pump I shorted the pump out and did not work all so the pipe that feed the pump are totally claps so could not get fuel to the pump so I am now going to change the pump and pipes and the fuel sender unit as well
