I have trouble every time I fill up my 04 suburban. I get somewhere between .50 to $1.00 and the pump clicks off like it is full, and this continues. I have tried other stations and still the same thing. Anyone else have this problem?

Gas tank may be vapor-locked. There is a solenoid-actuated valve that allows vapors out of the gas tank so that fuel can enter. If the valve gets stuck shut or breaks, the thing won't take any gas until you can relieve the pressure. Not really sure how its set up on a 'burb, saw it happen on an Impala this summer, but on the Impala there was a hose coming off the tank, and when we disconnected it, there was a rush of air and all the gas in the fuel filler neck flowed into the tank.

 

You may need to replace the valve and the box into which the vapors go (not sure what its called).

 

I would start by seeing if you can get at the hoses on top of the tank from under the 'burb, may be kind of difficult. On the Impala all we had to do was pull a piece of metal out of the trunk =).

 

You are sure theres no gas and its not just a shot sending unit though right? :crackup:

I have the identical problem with my avalanche. Since the burb & Avy share the same platform I'm not surprised. I've been freezing my butt off this winter trying to get my tank full. I think it is nothing more than gasoline backing up in the filler nozzle. Bad design imo. :crackup:

I have had the same problem in the past with my truck. It has not done it in a long time but is very annoying when it does. What I find helpful is to back the nozzle out of the filler hole some - almost to where it is barely even in. While it is somewhat of a pain to do because you have to hold the nozzle, it does click off as fast.

This works for me too. Some pumps I think pump faster than others. Occassionally when I fill up I will either pull the nozzle out a bit or go down one click on the trigger.

With those posting that you have similar problems, a word of caution. Turn your face away from the filler as you first loosen and remove the cap, fuel can spray in your face from the pressure.

 

With vapor recovery pumps (california and others) you have to wait a little bit after placing the nozzle in.

 

Other problem could be....if you are in the habit of pumping that bit more fuel in after the autostop, such as rounding up the dollar amount or gallon reading, that extra fuel actually back fills and saturates the vapor recovery (carbon canister) on the truck and doesn't "reclaim" the fuel vapor in the tank thus creating vapor pressure inside the tank shutting off way early the nozzle.

The only time I have this issue is at stations in Missouri where they have the vapor catchers on the nozzle.

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...

      Different requirements for oil filters?

      // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn

      Alternate wiring for Kicker sub with Bose system. (DO THIS)

      By smooth68 · Posted

      I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads

      By glenn27 · Posted

      ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
