HELP! PLEASE! 88 f350 460
hey,... im try'n to fix a buddys 88 f350. cranks but no start. i can not hear the fule pump ingauge and charge the system when i turn key on engine off. i try to purge the line and their is no pressure. now its a dule tank truck, so im assumeing that theirs 2 in tank fule pumps (didnt see a external one...just some crazy filter thing?), neither of wich ingauge with koeo. i can understand if one pump died, but both...i dont think so? so im thinking maybe they both connect somewhere and the power, or ground to that is cut. i tryed jumping what i thought was the fulepump relay for it, drivers side firewall?, but with no luck. also, that relay i followed the power wire till it dissapeared into somthing in the bed and it had power to that point, i evin fixed a fuse, 2 bad splices, and a bad ground up to that point... any ideas? i need to get this fixed bad.
