Hi, I have fuel coming to the injection pump but not out of the injectors. Solenoid, filter and fuel pump are OK, bleeding done. What can it be? Any idea please? Cheers

Is the stop wire connected up correctly if it's a manual?
What condition are the fuel spill pipes like on the injectors?
Have you bled it properly - bled the filter? Then bled the injection pump - undo the cap nut holding the fuel return banjo on - crank it till it spurts fuel.
Then bleed the injectors - all of them - crack open the nuts on the hard pipes on top of the injectors - crank until these leak then tighten.
Once bled like that it should start...

It is auto. Will post pics of the fuel spill pipes. What can happen there? Can't bleed injectors, as no fuel is going there.
Will check the timing belt.
Thanks for help.

If you are getting fuel at the return line on the injection pump then the next is the injectors. How do you know you are getting no fuel to the injectors?

Sprocket turns when the starter is engaged, and looking through the oil filler cap the valves are moving...!

I opened the nuts on the hard pipes on top of the injectors. No fuel there when cranking.

leave them open, and also slacken off the return banjo cap on the back of the pump. See if that banjo spurts, nip up and then wait for the unions to start spurting.
When you turn the ignition on, can you hear the pump buzz?

Hi there. So I solved the thing. It wasn't due to solenoid or fuel but to the immobilizer. That was hard to found out but in the end... This may help somebody else in the future, I hope. Cheers
