Being methodical is the key. It's a series of "if/then" statements:
If there's power at the pump, but the pump isn't running, then it's likely the pump is bad. If there's no power at the pump, then it's likely in the relays / board / wiring If the pump is running, but the car isn't, then it's not the pump (IMG:style_emoticons/default/wink.gif) The hows and whys are more "analog", but solving the problem is a "digital" process. As @bkrantz and @rjames suggest...it all starts with testing the power at the pump |

QUOTE(rjames @ Feb 14 2022, 02:10 AM)  QUOTE I would get out the trusty test light (or multimeter) and check for power at the pump. If you have power, then you know the pump is the problem, Have you done this yet when the pump stops working? Had a similar problem, there was power to the pump but it still would not run. it was a newer pump, (But they can go bad also) Turned out the problem was in the ground wire I had run to the pump mounted in the front. Bad connection there. Increased the wire size from 16 ga to 12 ga and ran a different ground wire to the point under the dash. No problems sine then. YEMV |
