So, was running fine, going to double check my timing, wouldn't restart (tried, but couldn't keep running). No pump sound and no pressure on the gauge (I love you, fuel pressure gauge). Whacked the pump with a screwdriver handle, nothing. Pushed it into the garage, figured I would give it one last listen in the quiet, heard a little bit of something, then a little grumble from the pump and I had pressure again. Started up just fine.
To me that says fuel pump, not relay. Any other experienced folk have some wisdom? I need to move my pump up front anyway but I was planning on keeping the original. now that I am thinking about it, it did struggle to start earlier in the day as well but cleared up. Car sat for a couple months during the winter. |

Hmmm... Power to the pump and no signs of issues. Set my timing, drive around loving the new found peppiness and exhaust growl. Got it nice and hot, turned it off, pump sounded fine, started up without issue.
Would a dying pump recover like that or does that seem more like a relay behavior? In my experience pumps would just kind of poop the bed or at least make terrible noises. |

In my experience pumps would just kind of poop the bed or at least make terrible noises. a dead pump usually does not recover. but i suppose there is always the exception. the typical failure mode is internal failure. brushes wear down and jamb up commutator. take mr. p's advice. change it anyway. use the pump in the car to do the fuel transfer trick. i'm going to follow the tip. fuel prices are f'n nuts here. i drove up country a couple of weekends ago in the big citroen. first time in years i was touching the go pedal with a feather and driving under the speed limit. got into drafting semis. |
