Resolved, it was fault with wrong instaled solenoid and stuck bypass valve, our manometer was sucking air and was not showing vacuum so we didnt realise that valves were not fully open. Thanks guys for ideas.

Check for restriction or leak on suction side. Run engine off a separate fuel supply. If the transfer pump is known to be good and you closed off fuel return then pressure should have jumped up to the safety relief valve setting in the transfer pump but there was no change.

I have problem with pressure on fuel system, should be around 500kpa but it is 100, i have checked the transfer pump, eaven swaped from one engine to another, no change, I closed return valve while it was running (if it was bypasing pressure would jump) and no reaction. Does anyone have any idea what should i chack next.
