My truck will not start. If I spray ether in the breather it will start and stay running all day. Could this be my fuel pump? If so I heard there are two of them. Where are they? Sorry, real new to diesels????

take the fuel filter back off and look at the O rings on both ends and make sure you didnt pinch one of them
sometimes not but check that and see what you come up with also open the bleeder screw and pump on it and see if you are getting any fuel up to that point. If its pinced it wont prime at all.
check the o rings anyways
