Next, I would "divide and eliminate": see what you have at the fuel pump connector. Note: Before going further, do NOT expose fuel vapors to the potential of electrical sparks - especially when making voltage measurements with an open fuel tank!! (Course you know that, but you might not be the only one on the internet reading this!) If it is good there, then check resistance of both pumps, measured between the input power and the ground. Also, inspect both halves of the connector.

Re: Fuel pump hotwire
Ignore those readings they are just an anomaly...
The connectors are corroded due to water that was in the tank. |
