I just bought 1991 f150 4.9 dual tank the rear tank works fuel level and pump switch it to front and gauge drops to bottom and no noise from pump and will not start checked all possible contacts and did not see anything unusual is there any way to check wiring for power or any good thoughts?? I was about tempted to make some jumper leads to see if pump is good (taking wiring off rear tank and put to front to make sure not issue in tank) just grabbing straws
