Question about 2005 Chevrolet Silverado

1 Answer

My 2005 Silverado won't start. When key is turned, it sounds like it's starving for fuel, yet there is gas in the line on top by intake. My pickup is an '05, 4.7 V8,2WD, was doing fine, but within the last couple days it's been dying out while driving, now, won't start at all. Any suggestions Please? My wife is driving me crazy 'bout it.

Fuel pump may be working but not providing enough fuel pressure to operate the vehicle.Try to see if it will start with alternative fuel such as a sensor safe induction cleaner.If it starts then dies after it burns the cleaner then more then likely the fuel pump is bad.

Testimonial: "Yes, it starts, runs, but when I run the A/C it dies out, even putters a little, without it on. Electrical maybe? Wife swears it's an O2 sensor. Has a new battery, is it a relay maybe? any suggestions you have is helpful more than you know."

    The 02 will not cause this.The reason it's worse with the a/c on is because of the additional load the air creates operating.Would verify fuel pressure is adequate.Will vehicle stay running assuming the air is off probably running rough and can be started?Is the engine light on?Try cycling the key off and on several times will build up the fuel pressure after about the 3 or 4 time actually try and start see if it starts then.

2005 silverado 4.3 liter runs for 5 min then dies starts back up runs then dies

Sounds like a clogged fuel filter or bad fuel pump. If the fuel flow is restricted, then engine will start and idle but at higher speeds it will starve.

Engine turns over but won't start

Have you checked if it is fuel or spark related? Did it die while you were driving it? When did it happen? Does it have gas? I know that sounds dumb, but stranger simplier thing have happened. Timing chain?, Distributer gear worn due to worn cam? fuel pump?

2000 chevy silverado v6 vortec engine, died driving, changed fuel pump, plugs wires, etc. and still wont start. ever heard of that

1st, check to see if the fuel pump runs for 3 seconds when you turn the key to run (not start). If it doesn't run, then check the fuel pump fuse & relay in fuse box under hood, if OK, (spray starting fluid in the intake to see if engine fires at all), if no fire then look towards the ignition as the problem. There are 5 things need to start an engine: 1. fuel (delivered & pressure), 2. air, 3. spark (distributor/ignition module or pickup coil), 4. rotation & timing, 5. compression. any of these that are wrong or not there, the engine fails.

I ran outta gas on my 1998 chevy silverado v.6 vortec. i put more gas in it and pumped the accelerator a few times and it still wont start. how can i fix it is it simple

Best way to fix it when you run out of gas is this. Because you ran out of gas, means your fuel filter is out. When you run out of gas, you end of getting like a air blockage in the line. Now, professional way is to take fuel filter off and fill with gas and put back on, BUT i will tell you a back yard mechanic secret way. Is get a can of starting fluid ( you can get at any auto parts store) and while someone is in side the Pickup, have them ready to turn the key. You are outside with the hood up, and you will be spraying a little bit of the starting fluid in the air intake of directly in carb area ( if carborated) but just spray into air intake. Have them crank the engine, at same time you will spray starter fluid in air intake, just a couple of quick sprays. You will notice it will start and maybe die again. That is normal, you might have to do this a couple times to get things flowing. HOWEVER, what normally happens when you run out of gas, the fuel filter picks up all that junk that has been gathered in the bottom of fuel tank and it has clogged your filter. FOR SURE, if you replace your fuel filter, it will solve this problem. Thank You, and I hoped this helped you.

Car will turn over fine but won' start, as if it is starved for gas. the car is full and i have also checked the fuse for the fuel pump and it is fine.

but is the fuel pump working.if you remove the air snorkel and spray intake cleaner into the intake while someone tries to start the car and it starts then you have a fuel problem.either the pump,plugged fuel filter,fuel injectors not working,dirt in the fuel system.check the fuel pressure if it doesn`t start when spraying cleaner into the intake.

2005 Silverado 3500 with 8100 gas enginne, Truck lost fuel preasure at a stop sign, I noticed no responce when applying the throttle. So I put it in park and it ran very rough until it died after the fuel...

My 2005 GMC does not have a fuel filter anywhere. Must be another great idea that an engineer came up with." we will tell them not having a filter cuts down on maintainence costs" As far as not having fuel to the engine, I would pull the line loose ane turn the key on to see if you have any fuel flow you might have to cycle the key several times as the pump will only run for 3 seconds with each key cycle, maybe a rubber line has collapsed on the inside, happens on brake lines all the time.

Ran out of gas in 2004 Silverado pickup. Won't start now.

check the fuel pump relay to see if it clicking when you turn the key on if it is you need to replace the fuel pump easiest way is to remove the bed and position it on the top of the rear tires and bumper.then you have access to the fuel tank without the problem of pulling the tank and spilling fuel everywhere

I have a 1999 chevy 1500 with a 5.7 liter. If truck sets more than an hour I have to pour gas down the throttle body to get it to start. It seems to run fine after I get it started. But have noticed if I...

sounds like you have a problem with your fuel presure regulator

as for pouring gas down the tbi try turning your key on then off a few times wait about 3-5 secs for the fuel pump to prime the system and try that if the key prime works than have a mechanic presure test the f.p.r.
and try and remember there are a ton of auto salvage yards that will sell an fpr for like 20 bucks including the fuel rail
