Question about 2005 Chevrolet Suburban

1 Answer

2005 chevy Sububan 5.3L 4 WD w/Flex Fuel. For the 4 wks it has been hard starting. It doesn't stall, once I turn the key to start it if I don't hit the gas it won't start. Once I hit the gas the RPMS bottom out and then if I continue to rev the gas it stays running. I beleive it is idling low but I was told that's normal due to flex fuel. I just replaced the battery since my truck dead every 5 days but the battery was the original so it was old. I also have tried turning the key in the on position and waiting a few minutes and then starting it that seems to work. I am aware that the fuel filter is in the tank so I was planning on buying cans of sea foam and seeing if that works. It has 48,000.00 miles.

Have a fuel pressure leak down test run on the fuel pump. This is a symptom of the electric pump pressure check valve being defective, the valve is part of the fuel pump and it is mounted in the fuel tank. Also make sure you are using 87 Octane gasoline, higher octanes can cause stall issues on cold starts.

SOURCE: fuel pump not staying on 1993 k1500 350

Some GM products also incorporate the oil sender switch into that circuit for fuel pump, so that in case of an accident, engine shuts off, oil pressure drops, in turn, shuts off power to fuel pump. May be worth a look at what your getting for oil pressure, as well as checking switch/sender.

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

SOURCE: 1999 5.3 vortec silverado 4x4. Engine intermitient hard start.

Had a similar problem and turned out to be a fuel regualtor.
Be careful with the little o-ring. Tricky little devil.
There may be residual pressure in the line so be careful you don't take a shower in gasioline.

It was hard to start after warm up. Rough idle until driving. Then on shut off it was hard to start.

2005 Silverado won't start


Assuming this is a crank no start, open the gas cap, put your ear to the fuel fill as close as possible. Have an assistant turn the key on, you should hear the pump turn on for approximately 2 seconds. If it does not, have the assistant crank the engine while you hit the bottom of the fuel tank with a hard rubber mallet. Sometimes this will jar the pump enough for it to run.

Once a new key is programmed, will an old key still work in a 2005 Chevy Malibu?


Not sure about Chevy's, but when my husband lost his keys for his Ford, he got a new key programmed, and when he found his "lost" key, it still worked. Try it. Don't think it will hurt it if it doesn't work, but check with a dealer.

Civic hard to start, and when started shuts off


Try this first, and lets see what happens. Turn key to on, but not start, then off. do that about four or five times, then try to start. See if it starts, runs, then dies. Let me know. Have you had fuel pressure tested at all? If it doesn't start and run for a short while at least, take air intake hose off at throttle body intake, open throttle and spray a good shot of WD-40 into throttle body, then try to start. If it starts, you have a fuel delivery problem, maybe fuel pump or plugged filter would be first to check. Just because you hear the pump, doesn't necessarily mean it's getting proper pressure to run. Let me know what happens when you try this, and we'll go from there.

It does sound like the fuel pump may have a problem, however, usually when they go out they completely fail and don't work at all.

I would recommend changing the fuel filter first, which is not too expensive. If that doesn't help, you probably will have to change out the pump.

Good luck!

2005 Chevy Malibu starting problem


Sounds to me like you should check your battery and connections to it. Maybe they are dirty or corroded- not allowing full amperage to start your car or recharge the battery fully.

Just a relatively easy check and usually a no- cost fix!!!
Hope this helps you out!!

2005 Chevy Malibu starting problem


sounds like its a gas problem. i would normally say its the pump but if you replaced it already then its not likely. i would look and see if there is anything in the tank clogging the pump. something may have got sucked up in there while you are turning.
