Mercruiser 120 1.7DTI won't start

My engine won't start.
It's on my trailer and it was running fine when parked 6 months ago.
This week I have changed the timing belt. And today I have tried to start it but it won't.
I was afraid that I may have done something wrong with the timing belt, so today I've checked the timing and it seems that is OK.
I've checked if the stopped soleno´d has 12v, it hasn't. Very strange while it was working fine before the storage. So I have put a new wire with 12v on the stop soleno´d, but it still won't start.
I've primed the fuel system, no luck.
When I loosen the injectors there is no diesel when I start. So maybe my stop soleno´d is faulty, but it is difficult to remove.
The strange thing is that the engine doesn't fire up, even when I put easystart into the intake. Even without diesel it should fire up for a few seconds I think..

Anybody has any ideas what I should do now?

I have put 12v directly on the fuel injection pump, so I have bypassed the kill cord.

Don't know much about these engines, but obvious things would be:-
  • Check you've got fuel
  • All fuel line valves open
  • Out of gear
  • Connections of neutral safety switches all ok (gearbox and throttle lever)

there is fuel to the FIP, but there's no fuel at the injectors.
but also does not start on easystart.

Step away from the easystart! There's clearly something not right, but firing easystart into it is likely to create more damage.

Figure out what the problem is rather than firing something into it that over time will destroy it.

yeah, I know, but it is a way to find out which way to search. Today I have done a compression test, all 4 cilinders equal, so that is positive. Checked timing for the third time, and it is definately spot on. So tried another squirt of easystart, and the engine fired up for a few second and was running smooth. So now I'm sure it's only a fuelling problem. So tomorrow I will try to get the stop solenoid off.

You already know it's a fuelling problem-there's no fuel at the injectors. Put the easy start in the bin before you wreck your rings.
