Fuel Problem Ford 4630

Actually yes, smoke comes from the solenoid if I give it too many cranks

Then you probably have a bad solenoid or a loose connection on one of the large posts of the solenoid.
When the starter is energized, the poor connection heats up and you lose the connection until it cools. Eventually, it won't connect until you tighten it or replace the solenoid or starter.

I had a similar issue on the same model. Bad fuel cap would not allow air into the tank. I had cleaned the tank and filter system, replaced the gaskets and seals on the filter system and could not get the pump to bleed.
It seems like you have multiple issues.

The tank vents via the cap.
