Thread: 2014 diesel Hilux slow starting & loosing fuel prime.

You'd more than likely see them leaking if that was the case. First thing Id try from what he has said about it would first start in the morning prime it until plunger goes hard and see how it starts. If its happened after the injectors have been replaced id take the bleed off rail off it and check around where the tube goes into fitting for cracks, can be common for them to get damaged when undoing the nuts that hold it on if the nut twists the rail when removing it. Hard to tell on the internet....
