2000 chevy tahoe starts but dies when you give it gas

This is complex to diagnose. Here are possibilities:

Here are some possible causes and solutions:

Fuel pump relay: A faulty fuel pump relay can cause the fuel pump to stop working intermittently, which can cause the engine to stall. You can check the fuel pump relay by swapping it with another relay of the same type in the fuse box. If the problem goes away, then the relay was the issue. If not, then you can move on to the next possible cause.

Clogged fuel filter: A clogged fuel filter can restrict the flow of fuel to the engine, which can cause the engine to stall. You can check the fuel filter by removing it and blowing air through it. If there is no resistance, then the filter is not clogged. If there is resistance, then you should replace the filter.

Vacuum leak: A vacuum leak can cause the engine to run lean, which can cause the engine to stall. You can check for vacuum leaks by spraying carburetor cleaner around the intake manifold, throttle body, and vacuum lines while the engine is running. If the engine RPMs increase, then there is a vacuum leak.

Faulty idle air control valve: A faulty idle air control valve can cause the engine to stall at idle. You can check the idle air control valve by removing it and cleaning it with carburetor cleaner. If the problem persists, then you should replace the valve.

Faulty throttle position sensor: A faulty throttle position sensor can cause the engine to stall when the throttle is opened. You can check the throttle position sensor by using a multimeter to measure the resistance across the sensor terminals. If the resistance is not within the specified range, then you should replace the sensor.

Faulty mass airflow sensor: A faulty mass airflow sensor can cause the engine to stall when the throttle is opened. You mentioned that you already changed the MAF, but it's possible that the new MAF is also faulty. You can check the MAF by using a multimeter to measure the voltage across the sensor terminals while the engine is running. If the voltage is not within the specified range, then you should replace the sensor.

Faulty ignition coil: A faulty ignition coil can cause the engine to stall when it gets hot. You can check the ignition coil by using a multimeter to measure the resistance across the coil terminals. If the resistance is not within the specified range, then you should replace the coil.

There could be several possible reasons for your Chevy Tahoe to start and then die immediately. Here are a few things you can check:

1. Fuel system: Make sure you have enough fuel in the tank and that the fuel pump is functioning properly. Check the fuel filter as well.
2. Ignition system: Check the ignition system, including the spark plugs, wires, distributor, and ignition coil. Make sure they are all working properly.
3. Idle air control valve: The idle air control valve (IAC) helps regulate the engine's idle speed. If it's faulty or clogged, it can cause the engine to stall. Check the IAC valve and clean or replace it if necessary.
4. Mass air flow sensor: The mass air flow (MAF) sensor measures the amount of air entering the engine and helps determine the correct fuel-to-air ratio. If it's dirty or faulty, it can cause the engine to stall. Clean or replace the MAF sensor if needed.
5. Security system: If your Chevy Tahoe has a factory-installed security system, it may be malfunctioning and preventing the engine from starting. Try resetting the security system and see if that helps.

If you're unable to diagnose and fix the problem on your own, it may be best to take your vehicle to a trusted mechanic or dealership for further diagnosis and repair.

check fuel pump pressure- fuel filter --air filter --egr valve if carboned up clean or replace and cat converter feel the exhaust if feels restricted may be clogging up

hello good day, reverse your air filter, make the bottom to top,, if is not work change the high tension wires

Just for the record, its a throttle body not a carb.
Sounds like the injectors are not getting power or a ground signal from the computer.
You would check them with a meter or low voltage test light.

thats what it sounds like, a bad or clogged up fuel filter. if it bogs down when giving it gas, or going up a hill. its probably the fuel filter not letting enough fuel to engine. that is why it stalls at a stop. if this helps but not fully. check or clean idle air control motor. this is what maintains proper idle of vehicle. have a good day !!

Change fuel filter, check air filter, If this doesnt help, check fuel pump pressure, should be over 55 lbs.

IVE HAD PLENTY OF THESE GO OUT EVEN A MONTH LATER. AS FAR AS THE STARTING FLUID JUST TRY AND CYCLE KEY BUT KEEP IT FROM TURNING STATER OVER. TURN ON AND OFF ABOUT 3 TO 5 TIMES IT SHOULD BUILD ENOUGH PRESSURE TO START. TO START MINIMUN PRESS IS 55PSI.

could be as simple as a dirty fuel filter. or maybe the fuel pump has died..i will go with the fuel filter since you were able to get it started again.. also when replacing your fuel filter you should go ahead and get new plugs and wires.. a small tune up wouldnt hurt and would only set you back 100.00 dollers maybe.. hope this helps

did you spray the maf sensor or intake hole ?if you didnt spray maf then probly not! have some one turn the key why you listen in the fill gas hole for pump noise ? sould here somthing for 2 seconds at least besure you ear is there before key is turned , also check you ecu fuse to see if it may be blown .? also you could try unhooking battery cable for 20 minutes neg side only then rehook it and try to start it! good luck
