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. |

Not trying to be an (IMG:style_emoticons/default/bootyshake.gif) Had you tested with a DMM for power at the fuel pump rather than (IMG:style_emoticons/default/smash.gif) with a screwdriver you would have data and facts to work with and we wouldn't be guessing. (IMG:style_emoticons/default/poke.gif)
At least you had the fuel gauge which is data about the fuel pump output (i.e. fuel pressure). (IMG:style_emoticons/default/smilie_pokal.gif) What we don't know is that the fuel pump had input (12v & free-flowing fuel at the pump inlet) |

The screwdriver was there in my hand. It was made for whacking. It has fuel, it is the question of power that I will have to pursue... maybe even with your damn multimeter. |
