...."I’m pretty much berkeleyed. That’s my considered opinion. berkeleyed." So, the 78 is currently torn apart in the garage. The 06 just took a dump. Pretty certain it's the fuel pump. 2 reasons for that assumption, multiple continuous misfires, multiple injector malfunctions for codes and the most important part: I just filled it up. 26 gallons of fuel. 

So it looks like I'm riding the bike more than I anticipated this year. 46* was a little chilly this morning especially since I wasn't prepared for it. 

Damn.... I'll check fuel pressure tonight but it looks like the 78 is getting patched back together to be a daily for a bit.

No idea what the 78 or the 06 means, but if'n it were me, I'd assume the 78 is a project and the 06 is a daily driver.    That means pay someone else to deal with the 06.

 

Just sayin'. 

 

Sometimes you just have to call in reinforcements, and they probably have a way to deal with a full gas tank or a storage thing to hold 20 gallons or so temporarily.

Looking at his garage, the 78 is a C10 and the 06 is a sierra 1500. 

What are the options, as wonko mentioned, of farming out the 06 to a shop? Winter riding can be done to a point, but once snow is on the ground, it gets much more difficult on 2 wheels. Now combine proper gear, snowmobile and heated, with a side car it becomes plausible if you are sufficiently masochistic. 

Either way, good luck.

IT's actually easier to yank the bed. 4 bolts with the impact and slide it back 12 inches to access the top of the tank.... if that's what the problem is. The 06 is her Sierra that was getting ready to go to the body shop. the 78 is my "New Old Truck" that;s strewn across the garage.

Pick up another (running) project car? :)

ALSO... why don't fuel pumps die when you're low on fuel? I mean this sincerely, every in tank pump I've ever had go bad was after a fill up.

You just need an agreement like "half of all the cars I own must run at any given time" then pick up cheap runners from craigslist to even out the average... Not that I'd know anything about that.

btw, anyone know the correct fuel pressure for a 2006 4.8 Sierra KOEO and KOER?

Also, the gauge has been crazy for the last 3 years. I guess now I get to fix that too.

Doesn’t matter. Found the problem. Mice. Ate through #7 injector wire. Well at least I don’t have to take the bed off yet.

Darn.  I was hoping to use your research to find out about why fuel pumps do that.  OTOH, apparently when you turn 42 you get the answer to Life, the Universe, and Everything.

My customers (professional auto techs) are always asking the same question.  They don't like that very much either...but they get to deal with it continuously.

Many times, people will do the stuff they understand to try to fix their car.  Running bad?  Hmm...I know how to fill it with gas.  That might fix it.

Usually it’s to keep the the tank from rusting while it sits in the side yard for a decade or so?

It kinda would make a little sense for the average non mechanic. Low fuel pressure = "Oh, I must have gotten some bad gas, I'll just put some good stuff in it." Fill the tank up and the pump finally dies. That's my story and I'm sticking to it.

I think filling the tank probably stirs up sediment that ultimately ends up in the pump causing the failure.
