This isnt for a lightning, its my friends 90 mustang. We just put on a + cable for th battery ad now the fuel pump wont prime?? All wire at snug that go to the starter selonoid. any ides? oh I chek fuses an the fuel cutoffin the trunk all seem to be ok

 

check with a volt meter to see on the actual pump if your getting power, if not you know what that means, if so you have a bad pump.
