Asked by rharrison Jan 10, 2008 at 10:56 PM about the 2004 Chevrolet Silverado 1500

Question type: Maintenance & Repair

Can anyone shed some light on this problem. After driving my 04' Silverado 1500 all day without any problems, after the truck sat in the driveway for a couple of hours, the truck started right up, but then after about 10-20 seconds it shut off. It now continue to do this. It starts normally, but then shuts off. I tried removing battery cables for a while and replacing, but no difference. Has anyone had this problem?

Thanks for the help!

sounds as if you have a fuel suply problem.you did not mention milage,so have you replaced the fuel filter,cleane throtle body with carb. cleaner carbon will build up at butterfly and keep it open,just remove air filter over t body clean until all black ring is gone crank and see what happends,if no change ,probley fuel pump is bad.good luck,and let us know how turned out.

I would also agree that it sounds like a fuel supply problem. The cheapest thing is to replace the fuel filter and then probably the fuel pump (in tank). I would also check for a fuel leak from the tank to the injectors. You may also consider that you could have a clogged fuel injector.

Thanks for the help! Sorry in my delay in replying, just got back in town. I'm going to start with the fuel filter. I'll post results. Rob

After a brief discussion with the dealer, I found out that the 04' Silverado does not have a fuel filter any longer. It simply has a screen at the bottom of the fuel pump. Also, they told me that it doesn't sound like the fuel pump, because when that goes out, it goes out, it doesn't continue to run like my truck is doing. My truck continually starts up without a problem, but dies after about twenty seconds, so now I'm back to square one. Looks like I need to get the computer diagnosed. Thanks Rob

If this only occurs after the engine is hot, it may be an electrical problem. When the engine is hot, two things occur: (1) thermal effect on connections - electrical connectors expand and dry solder joints or worn connectors may suffer poor contact. (2) thermal effect on components - heat (or extreme cold) tolerance of semi-conductor components may vary performance of power supply throughout the system (to sensors, solenoids, ignition etc) and exhibit unusual engine management behavior. This is evident from several GM technical service bulletins concerning intermiitent electrical problems caused by faults with the power management computer and power distribution box. Be cautious about the GM repair by replacement policy. This will cost you time and money if it is not covered by a current warranty.

disagree,the04 does have a fuel filter .All electric fuel pumps have a sock that goes on the bottom of the pump.check under door on driver side,nside frame rail you should see the filter.in my dealings with the dealership-shop their is usually 1 person that knowes what he is doing the oyher so called mechanics are hired off the street and dont knoe much they all go to the 1 person that knowes.

Actually the Silverados do not have a fuel filter. They removed them from the design in about 2000. My 2001 doesn't have one outside the fuel tank. I've traced all the lines because I didn't believe it either but all they have is the screen at the fuel pump inlet and the screens at the injectors.

At a dealership it all really matters, some guys are there because they are good at certtain things. Not all guys are great a diagnosis, so you have a couple good guys who know diag who then take on the harder jobs.

Don't know if this helps but my Grand Voyager (Caravan State side!!) would be fine and then on sunny days mostly I would return to the car to find it start up then die like a fuel or alarm problem. I then found out that if you remove the instrument panel and look at the circuit board it normally has a dry joint. I done this and sure enough one of the solder joints had a broken ring of solder all round it. I resoldered all joints (just in case!!) and it has not done it once since that was over 1 year ago and it has been out in the sun on some hot days!!

I am not an experienced mechanic but i am in college for it. the first thing i would do is find some someplace that has a scan tool and look at the o2 sensors, and mass air flow sensor. i really don't know though. does it have a check engine light on?

TPS sensor maybe? Does it run rough for those 20 seconds? Maybe vaccuum leak? Need more info?

Unplug the mass air flow sensor and see if it stays running.I had one fail and that is how it acted.I unplugged it and it ran fine although I got a check engine with it unplugged.I replaced it and no more problems.

Turn the key so the lights are on but not the truck, let it sit for like 60 seconds that way the start it. Just had the same issue. Its a security feature that needs to reset after the battery cables are disconnected. After this it should run fine

Thank you Alexander. Have a 2000 Tahoe Z71. Changed battery and could not start engine (ran 2-3 seconds then shut down). Tried resetting the fuel rails via turning on ignition for 5 seconds--no joy. Read your comment, above, turned system on for 65 seconds, turned it to start, and it started up and kept running. As a note: Owners manual only states that under such circumstances to take the vehicle to the dealer to reset the security system.
