F150 wouldnt start

I'm having a smaller problem on my 90 F150 XLT (5.8l, dual fuel
tank)). I would run with no problems but once I let it sit, it has a
hard time starting up (turns over nice, just doesn't start - low fuel
pressure?)

I have noticed that I have no problems when I leave the truck on the
forward tank, problem shows up pretty consistently when left on the
rear tank.

I am assuming a bad fuel pump, just haven't had time to work on it.

Forgot to say:

When trying to use the rear tank, I can hear the whine of the fuel
pump for up to 10 minutes before it shuts off and I can start the
engine like there was no problem. I leave the key in the ON position
and wait.
