Relocated battery to bed and did some upgraded wiring. Now truck wont start unless i pour gas in throttle body. I dont hear pump. I replaced fuel pump relay and checked fuse. I found i have no voltage coming from ecm. I jumped that wire from battery heard relay click and found voltage down to tank harness. Is this a sign ecm has given up? Is there something else to check? Would a bad ground at tank cause problems that would tell ecm not to supply signal to relay?

Well found out that if tank ground isnt perfect ecm will not send signal to relay. Saved myself a pump and a ecm by fixing that ha
