help! no gasoil coming

[dahicori]

Hello everyone ,

So i have no gasoil coming out the return fuel line,

I red the threads concerning this well covered problem on the forum, but what really bothers me is that I made the engines turn yesterday, it starts right off (timing, preheat, valve clearance were all done right) , as usual bw two weeks. i turned the key off, and today at first attempt to start, no cylinder even tried to explode

i really dont get it
pump solenoid is ok

i have no air coming inside the circuit...that's for sure

maybe i should check the tank, filter?

thank you..
