I have a 2001 Chevy Tahoe 5.3 I was driving down the road and all the sudden it stopped running. I have replaced fuel filter, spark plugs, cleaned fuel rails and fuel injectors, also crank position sensor. It still will not run. It starts and runs for 5 or 6 seconds and cuts off please help what is wrong with my tahoe.

Hello. Yes, your Chevrolet's security system will 'shut-down' the ignition system; causing your truck to start but stop instantly. The truck 'thinks' it is being 'stolen' and will 'enable' it's security system to 'hamper' stealing it. Good luck and keep me informed; if you want to.

Those are codes for bank too lean. Look for vacuum leaks, failed cat converter, exhaust leak, plugged screen on in tank, failing fuel pump, bad fuel pressure regulator, dirty/weak injectors, bad ground,..I'd take it to a shop, a good tech can track it down in under 20 minutes, it's all about the tools.

check if the fuel filter needs replacing

Sounds like you have a fuel pump going bad or a clogged fuel filter. Change your fuel filter first.

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 !!

I would replace
1. spark plugs. Do not go cheap on the plugs use the proper AC Delco spark plug
2. cap and rotor
3. spark plug wires
4.fuel filter
and then i would have a fuel injection cleaning done . there is not a timing adjustment or air fuel adjustment this is all done by the PCM ( Powertrain Control Module )

the fuel filter is located down under the middle of the frame rail, on the drivers side,remove the lines from the filter, look out b/c some fuel will come out after diconecting the line. replace with the new filter make sure you get the "FLOW" "should be marked on the filter" pointing to the front of the car

a partial plugged cataylic convertor would case this. and under a load like towing a boat should have thrown a code. a exhaust back pressure test would show this. but normal driving would not throw a code.

god bless you for serving our country!!!
