If it's a shuttle type pump, mounting it horizontally like mine was can shorten it's life. If it lets you down in the middle of nowhere then they can be resuscitated with tap from a 1lb 'encourager' or the handle of a large screwdriver :-)
If the wiring is sound and there is not an isolator in the way, then it may indicate that it is on it's way out and will probably need replacing like mine did. I put a new red top in and mounted it vertically as per spec and have not had any trouble since.
