aoist Posted June 23, 2022 Share Posted June 23, 2022 My 2002 pathfinder has a peculiar problem , if it is not started within a few days it won't start. I have to pull out the air filter and squirt in some starting fluid to start it. Any clues as to the cause of this? Clogged fuel filter? Or? Thanks much Tom Link to comment Share on other sites More sharing options...
Slartibartfast Posted June 25, 2022 Share Posted June 25, 2022 That is a weird one. If it runs normally once it does start, I doubt it's the filter. Any codes, any other issues once it's going? Link to comment Share on other sites More sharing options...
adamzan Posted June 26, 2022 Share Posted June 26, 2022 Sounds like the fuel pressure bleeds down and then there is air in the system. This can happen if the little rubber line on the the fuel pump is damaged somehow. Link to comment Share on other sites More sharing options...
aoist Posted June 26, 2022 Author Share Posted June 26, 2022 (edited) Yes, I think I figured it out, a failing fuel check valve inside the gas tank. I'm just going to install a check valve as closest to the gas tank as I possibly can. Maybe a simple $10 remedy, we'll see.
