A few months ago, my pickup broke down, and apparently the fuel pump needed to be replaced. It cost a lot of money because the vehicle broke down in Fairbanks North Star Borough, but despite the exorbitant cost of towing and repair I was extremely lucky to be able to drive the vehicle out of that district without being cited and having the vehicle impounded and auctioned off, which is the normal course of action in such a district, because most people don't ever want to be seen in the same vehicle after any kind of breakdown or incident with first responders or law enforcement — any "brush with the law" or contact with first responders for any reason on the road jacks up your insurance rates, and goes on your record like a criminal offense or traffic violation, and accumulates "points" by which the cops can eventually have your driver's license revoked.
Recently I ran out of gas and it died. I put about 3 gallons of gas in the tank, and tried to start it. I am not sure what the problem is. The fuel pump measures about 7.5 ohms resistance, and it does pump fuel when I apply power to the power lead on the relay block directly from the battery, so I assume it is still good since it was recently replaced.
I pulled out the fuel pump relay, and discovered a +12V potential on both sides of the relay coil, despite a lack of pressure in the fuel system. The relay is not turning on, because the normal return circuit for power to the relay coil is not grounded, but actively forced to +12V potential apparently by some other relay somewhere which has failed to switch.
There are still various wiring "issues" due to severe and persistent corrosion that has unfortunately occurred under normal everyday conditions of use, which may have unfortunately burnt out the previous fuel pump.
