Can you deadhead a system without a return line, or is it already deadheading?

I don’t believe there’s a way you can do that on that type of system.

Can you use this test to determin if bad MPGs are related to fuel pressure?

It would be better if you posted this to Service and Repair.

Hard to say what the problem is. It’s not one I’ve encountered on one of those vehicles in the past. Likely something electrical. A good place to start would be a wiring diagram.
