Yeah the lift pump is under the hood. It got dark on me last night so I'll be back at it today.

Let's say the fuel did gel last week when it was about 10* here - wouldn't it have un-gelled now that it's up around 40? Or once it's gelled does it stay gelled?

I've had the truck for about 10 years, rarely drive it (avg 2k miles per year), and it has never failed me before no matter what the temperature is. It seems like if it's a gelling problem it would've bit me before now, but everything I know about gelling I've learned since yesterday.
