Right guys this is the story.

A van at work come in with a knocking noise.It sounded like diesel knock.I got the fault codes and im sure they were cam timing?? and fuel solenoid??(eve got them written down at work).So i asked one of the lads at worked who worked on fords for years,he said it was the sensor/solenoid inbetween the fuel pipes on the pump.So i took the inlet manifold and the fuel pipes to get at this sensor.The fuel solenoid valve came and it looked nothing like the one inbetween the pipes.I noticed there was a sensor at the back of the pump.I took it out and it was the same as the new one.I repaced the sensor and joined the wires together.

I rebuilt the engine back up and it wont start now.Ive put an electrical pump between the fuel filter and the fuel pipe to suck the fuel through.Im sure it must have an air lock.If you squirt some easy start down the inlet pipe the engine will run.Ive been doing this and was hoping it would help suck the fuel through.

Ive also cracked the injector pipes off to get the air out.Should the fuel squirt out??

I was thinking about taking the new sensor out and refit the old one.

Any info would help.Thanks.
