Can anyone tell me whats up here...
Its been kind of cold up here at night maybe -15 or so, I just switched to a winter thermostat.
My truck has been running OK. Sometimes it would die out on me as i would come up to a stop sign once it was first getting warmed up (after 5 or 10 minutes it would be fine, it might have done it a couple times after that) whenever i would drive it.

Today, I pumped the pedal a few times to engage the choke. It revved right up to 3000, bogged and died.
I tried it a few times same thing..
I said fukk this, Started driving it and it was real boggy. I blipped the throttle so it wouldn't stall, and started driving.
It was making small backfires, I turned down this street that had an uphill.. It barely made it up the hill, felt like I was driving a lawn tractor.

I said fukk this, im bringing it back and just parking it. Well, I go to turn around, it bogs and dies. I try to turn it over, it turns but won't fire. Wait 5 minutes...maybe it's flodded...pump the gas, try again..nothing. Tried this again 3 times.

Still nothing, i pulled off the carb filter (weber), took a lil whiff, didn't really smell like gas. I smacked my mechanical pump around a few times with a soft hammer, tried to turn it over and it ran for a second and died. I kept doing that until the truck warmed up to operating temp.

It still bogged, but it drove. I couldn't come to a stop or it would stall. I have to either blip the throttle or have constant throttle so it doesn't die..It's home now.

Discuss.

Accelerator pump on the carb maybe? Mine did a similar thing and it was the pump on the carb not working properly.

Hope not, things got like 30,000 on it. Mine did it before I put my weber on too. But hey..you never know I guess right.

Anymore ideas? keep em comin

where is your fuel filter?If on the firewall,check and be sure it hasnt picked up some H20 from tank condensation and freezing up.Dump a can of HEET or STP gas tx in tank to remove moisture and see if that helps.BJ

you can always just pour some gas in the carb manually and see if it clears up any at all. if it does then your starving for gas. either clogged filter/line. or bad pump.
