I Have a 1997 Blazer I have to put fuel in the carburetor to start it.... when it starts it revs even if I don't give it gas then it stalls out. It ran fine for a day or two after sitting for a while.

I had a 1997 s10 4*4 with the 2.8 v6.
mine do that I had to pull the gas tank replace fuel filter plus had to take undo the line from the intake and blow air thru it. Make sure all u're filter are replaced and y u have the tank down replace the fuel pump. I hope this helps u

sounds like ur fuel pump is burned out (broken impellor) get a new one.
of course she revs and dies if u pour fuel down the carby...duh.

Is it electric or mechanical pump? Electric is with fuel injection. If its fuel injection, you should hear the pump run when you turn ignition switch. If u don't hear it, try starting, if no, turn off then on. It will self prime. Carburetor is with mechanical pump. I usually put few drops of gas in the carb. Start it, if no, more in carb till it stays running.

your carburetor should have a fuel filter in the carburetor body where the
fuel line enters it replace it and, any other in-line fuel filter the engine might have

It's starving for fuel. The main component there is the MAS -- mass airflow sensor, very common to go bad. Tap on it and sometimes that will make it rev lower or stall. It's inline with the black tubing that goes to the air filter. They run around $200 but are very very easy to put in yourself with a little care.

This sounds like a couple different things. Lets start with the easier idea first. You need to locate the fuel filter and remove it and blow into the end that points to the carburetor. Point the other end at your hand or in a cup and catch the gas that comes out. If there was a good bit of debree then replace it and see if it fixed the problem. If it did buy a new filter next time it starts acting up, If not then it would be wise to check all the vacuum hoses for leaks or if one has come loose. If you can't see any leaks or loose ones then get a can of carburetor cleaner and as the engine is runnoing spay short spurts around the motor area. If the engine revs up to a faster idle then there is a leak. Do not spray right at the throat of the carburetor intake. That will rev for sure and there is nothing wrong there when it revs up. It would be like giving it gas.
If you find and trace down the leak stop it up or repair it. If nothing can be found then to the next step.
This also acts like a caburetor acereration pump. That is inside the carburetor and is a piece of rubber type diafram that moves back and forth and aceleration is given to the vehicle. These can get a pin hole or harden after time and you will need a carb rebuild kit. The kit should be under twenty bucks at schucks. Let me know how it turns out. I wish you well. The Raz

You can adjust the carburetor with a straight blade screwdriver.Remove the air cleaner and have someone push the gas pedal,you'll see a lever connected to the carb moving back and forth,this is the accelerator linkage.While looking straight at the linkage you'll see a screw between the linkage and the carb.Using the straight blade screw driver turn clockwise a quarter turn.Replace the air cleaner and start the engine.The RPMs should be higher, now hold the brake pedal and put it in gear.Stays running,your good to go,otherwise give her another quarter turn.Now this is a "get-by"solution,you need to give some attention to your engine by giving it a tune up!That means changing:distributor cap&rotor,spark plugs&wires,carburetor rebuild,oil change and lube.Oh yeah,tighten down the four 1/2" bolts holding down the carburetor too!You could have a vacuum leak under the carb or even a vacuum line disconnected.This will also cause the low idle speed!Good luck!

I have a 1997 626 2.0L 5speed when im driven it like rev limits cuts out around 3500-4000rpm, and when i rev it up and past 4000rpm it stalls, anyone have a idea whats wrong??? thanks i just replaced the crank sensor and egr and still. good power put cuts out

Your 95 Blazer does not have a carburetor (correct spelling too) It is fuel injected so injectors are used for each cylinder instead of a carburetor. If you run out of fuel and your vehicle is facing uphill when that happens you should have some fuel in the tank left. When leveling at a level position the vehicle will start again. You see the fuel pump is in the fuel tank and fuel is needed at all times to prime when starting. If on a grade the fuel goes to one end if only a gallon or two is left and the pump will **** air only causing a stalling problem I added all this in just so you remember this incase it ever happens to you

have you checked the fuel pump? mine would shake rough then stall... i doubt it is the tune up but check the fuel stuff
