i know this is a mustang site but i was thinking some one on here might know. i was helping a friend replace his front fuel pump. we got the tank down replaced the pump and put it back up and now it wont start. the rear tank wont even turn on any more[:@] we were thinking that we blew a fues or relay switch some where that we cant find. we did find a fuse in the fues box that was blown and we fixed that and still nothin. we looked at the enertia switch and that wasnt poped. were stuck and dont know where else to look. we were thinking that it has to be a fuse or relay switch some where since none of the tanks are working. any one have any ideas on what could be wrong?
