The fuel pump circuit goes through the oil pressure sending unit. If the unit thinks the oil pressure is too low, it will shut the fuel pump off. Make sure the oil pressure unit is correct for your vehicle. If you disconnect the harness at the sending unit the truck won't start and run. You can try re-seating the connector on the sending unit again. Check the terminals in the harness connector, make sure they are tight.
Let me know.
Regards,

Sorry to say its your head gaskets. Probably from the overheating it wore out the gaskets. that milky stuff is your coolant mixing with your oil. Good luck. Suggest you take it to a pro. the gaskets are easy to change, it's everything else in the way to get to them that requires special tools and experience. Let me know how it goes. I have the same thing with my truck but not real bad. If your truck is running smooth and doesn't feel like its missing, or when your start it no puff of white smoke comes out your exhaust it's not that big of problem. if these are happening then i would get a quote.

If all your other gauges work, more than likely you have a bad sending unit in the gas tank or bad ground to the sending unit.
