Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Had a search around but didn't find my answer. Why does my box not like to start with its usual ease when the tank is near empty? No problem any other time... Thanks.

POST 2Original post

Have you tried loosening the gas cap when the fuel is low?

POST 3 / ORIGINAL POSTEROriginal post

I'll give it a try before next fill up. So tank breather/evap system issues?

POST 4 / ORIGINAL POSTEROriginal post

Okay, I'm pretty sure it's not breather issues. No difference with filler and flap open before starting on near empty. I'm pretty sure I'm experiencing fuel pressure bleed-down when the fuel level is near the point when the low fuel light will come on.

POST 5Original post

Did you ever find a resolution to this? Having a similar problem when I’m below a half tank.

POST 6 / ORIGINAL POSTEROriginal post

Nope. When it’s cold and close to the low fuel light coming on I have to crank it for a few seconds. Once warm it’s fine.

POST 7Original post

Run a few tests, do a fuel pressure test then a fuel pump test. Here are two videos on how to do it at home. Fuel Pressure Test: https://youtu.be/hddx5Ux1v4Y Fuel Pump Test: https://youtu.be/wEWepuDUes4 Brian

POST 8 / ORIGINAL POSTEROriginal post

Thanks. I’ll try to take a look this weekend if time permits.

POST 9Original post

Another thought: The problem could be battery voltage related. Check the battery voltage at cold start vs hot start at the battery and at the starter.

POST 10 / ORIGINAL POSTEROriginal post

Thanks for the response Mr Stone. Hadn’t thought of that. Absolutely no trouble from cold with anything more than about an 1/8th of a tank of fuel. Below that and it needs to crank a second or two to start. Waiting on a package from LN to get my water pump issue out of the way. Then I’ll get back to this.
