I have no power at the pump.
I have 12.4 volts at pin #13 on the relay board. No power at pin #5 or 7, old eyes can't see the stripe colors very well. Fuses are good. Am I missing something? Thanks in advance. |

Here's what I finally did on Matt's car. Hopefully this will rid us of the fuel pump gremlins for a while. Once I'm satisfied we've cured the problem all the female sockets will get a dab of dielectric grease.
http://www.914world.com/bbs2/index.php?s=&...t&p=2532812 This I got from Doug. Much easier to read. Just remember the power supply relay has to work to power the fuel pump relay. Took me a while to get that to sink in.  |
