My 88 Ford F150 W/300 6 cyl eng will not start. Suspect fuel problem but
when fuel line was disconected it had no pressure. Cahnged main fuel pump and still would not start. Checked old pump and it works.
checked the wires with volt meter and no power. Checked resistance and got a pos reading on both wires. Has duel tanks but switching them does no good

Hello,

these trucks had a problem with the switching valve not working and cutting all gas off. It is located between the two tanks at the frame rail.

Here is a guide as well to go over the basics if the valves checks out.
