Re: How To: Replace the Fuel Pump Relay Module
If you have the benefit of the time to do it, I would think that the use of a soldering iron and the application of a dab of solder is a much cheaper alternative.
Why throw out a perfectly good module and swap it for a part that has in all probability the same weakness in the solder joints.
I do not think that it is mileage that makes this fault occur, the weakness is there as I saw when I examined mine with less than 20,000 miles on the clock. I am sure that new modules have this fault and the solder joint is nigh on a dry joint to begin with.
To do the repair properly the solder should be wicked away from the area, the terminal cleaned and then re soldered. The terminal originally looks black to me and that is not conducive to a good solder joint.
