Ok guys,

So over the weekend I filled my car up from a 1/4 tank twice. Both times I did this when I got back in the car and tried to start it, it simply keeps cranking.

After I let it crank about 3 times for about 2-3 seconds each time it will finally start. After that first start its fine though, any ideas?

 

Maybe sparkplugs? Lol just throwing out what I'd check for. Or maybe needing a new fuel filter? Could be a little dirty. I'm just thinking of simple stuff tho

 

could be fuel pump or the fuel filter which has happen to someone who is completly stocked in my area. fuel filter could be the issue take to the dealer and have them fix it. fuel pump could go out because you allow your car run 1/4 everytime you refuel which is bad for the injectors and fuel pump. I never let my car run empty unless I'm cleaning the internals and I'm at 8500 miles without issues with either fuel pump or filter.

 

that happend to me once and took it to the dealer... they fixed it an now its starting to do the same thing... its always right after i put gas on the car... idk what it was tho...

 

Yeah I heard that your not really suppossed to let your car run past 1/4 of a tank because it's not the best for the car.

I'd check the fuel pump or something that seems to be the leading cause with any fuel related problems with our cars

 

Well I can still hear my fuel pump working fine.

I just threw a code though something about the fuel pressure regulator. I picture this being bad....

 

I had the same exact problem. I also got a CEL. I replaced the Evap Purge Solenoid and its been fine since. Its easy to swap and like a 15 dollar part.

 

EVAP solenoid

 

where di you buiy it?

 

Evap solenoid

 

Sounds like my exact problem.

Do you remember the part number by any chance?

 

12608378

My dealer wanted like $40. I got it on ebay for $20

 

where did you get the part at?

 

What CEL did you throw? do you remember?

Thank you, part ordered.

 

Evap purge solenoid.

edit: just read the whole thread lol

 

The 1/4 tank rule is for older vehicles, I have ran mine to E and had no problems. Your pump has a screen and you have a fuel filter and as long as you keep up maintenance on the filter you should have no problems as far as sediment in the fuel. I'm guessing the 1/4 tank problem is just a coincidence and it's really just your evap.

 

might wanna do a search for the guy that had his clogged due to gunk in the little filter. Much easier to keep it above a quarter.

 

This was the CEL I had

[ECM] P0496 - Evaporative Emission System High Purge Flow (SES) (Old) (History) (Current) (Immature)

 

The 12608378 is an old number. It changed to 12592015. The new number is a few cents cheaper. But, since your buying one I would go for the newest number. GM will let you order either one. They have plenty of stock of each.

 

i run mine until the low fuel light comes on all the time, no problems in 3 yrs now

 

I usually hit up the gas station when I get to 1/8

 

The problem has nothing to do with having a 1/4 tank. It's putting the tank to full thats the problem. P0496 is a dtc for the purge solenoid being stuck open. The purge soleniod purges fuel vapors in the gas tank to the engine, when the pressure rises too high. Your purge soleniod is stuck open. So when you fill your gas tank to full the fuel is being sucked through the purge solenoid and flooding the engine. You can test it before you start spending money if you have a vacuum pump. Remove the purge solenoid from the vehicle. Takes no time at all to do. Put the vacuum pump to the intake manifold side of the purge solenoid. Pump the vacuum up to 20hg. If it dosent hold vacumm or wont allow a vacuum to pull, its bad. If you dont have a vacuum pump you can try the less perfered method and suck on it. If you can suck any air through it at all, its bad. Not highly recommended, as there will be oil and fuel on it. But i can almost tell you 100 percent it's the purge solenoid. If it was the circuit causing the problem it should have set a different dtc.

 

had a 08 lt bolt for 3 years and never had a prob letting mine go down. also never had never put in reg. gas always put in 91 octain and my new 09 ss/tc has never had a prob doing it eather. also my girly has a hhr and same thing no probs and she is pushing 70,000 miles

 

umm, actually it isn't just for oler vehicles.

sure these fuel pumps are designed to put up with abuse, but there's one fact that doesn't change;

1. the fuel pump is cooled by the gas it's supposed to be submerged in.
2. if you constantly run to bone dry, your fuel pump will burn out faster than some one who doesn't do that.

/trying to help

 

Well put gas in this morning, from bone dry almost, worked fine. No problem. What the hell haha

Bad gas maybe?
