that would depend if it is on a level surface, normally it would start up,
as far as the relay goes, look under the hood at the fuse box/pdc, it should
specify

Just a suggestion and warning that my son inlaw went to the trouble of
changing out his feul pump only to call me because the new one wouldn,t
work. found a broken wire about 3 ft from the pump were the wiring crossed
over a frame member. So before you install the pump and then cannot return
this expensive item do a voltage check at the pump, or try the old pump to
be sure it is defective,
