Question about 2000 Chevrolet Suburban

1 Answer

Engine cut-off at high speeds

I have a 2002 Surburban. Lately, at high speeds, the engine simply cuts off. I have been fortunate to coast to the right and come to a stop. Usually it starts up again on the first try, but lately it has taken a few attempts. I have taken it to the dealer where I purchased it but they are unable to find anything. Any thoughts?

    I would suspect the electronic ignition module.

Any thoughts? yes lots but none that would be helpful LOL

But seriously it sounds like one of the sensors is breaking down, but this should have show up on an electronic diagnosis at the dealers so maybe there is a broken wire in the engine loom thats parting as a set resanance due to speed and sound of the engine. i know this sounds wild but i have found this on other motors. its one of them hard to find things.

Would the electronic distributor pickup cause a vehicle to spit,sputter and cut out at a high rate of speed ????

First you can not put Bosch plugs in it. Also watch cheap wires from parts house. Also check fuel pump pressure at high speed. Also watch for Catt converter plugging. Try unscrewing up stream o2 on both sides then drive. If goes away plugged Catt. You can scan those and see fuel values. Then you can tell. Any codes?

Fortuner- engine cuts out whilst driving , switch ignition off and resart this has started after a fuel filter change. this normally happens when overtaking another vehicle

make sure the filter is installed in right direction and that you used high pressure rubber hose if you replaced any...or that the seals are in place if you had to use fuel line disconnector tool...

My car stops verry often especially when i reduce the speed to the traffic light.Could be the fuell filter?or the petrol got dirt in it.

I suspect a vacuum leak -probably in the brake booster-which is making the engine run lean and cut out. Try coasting up to the lights with out your foot on the brake and see if it cuts out when you apply the brake to stop. Run fault codes to check for a sensor fault.

1983 Buick LeSabre Wagon, cuts out driving down the road

Find the EGR valve on the intake and locate the vacuum hose that is connected to it. Start the engine cold and as it warms up, pull the hose off and if it idles and drives fine, the EGR valve is bad and needs to be replaced. Please rate me on this answer.

Chevy 6.2 suburban cuts out

Have you changed the fuel filters lately? If not, do so. They should be changed every spring and fall because of wax build up. This is more critical in the fall, usually mid October, because the wax will stiffen in the cold weather and block fuel flow. Also check the fuel return line for blockage. A copy of Haynes Diesel Repair Manual, part # 10330 could also provide some valuable diagnosis and cure advice. It hqas a specific section on diagnosis and on the 6.2. Hope this helps.

Truck broke down wont start.

There is no Inercia Switch to reset Like Ford
Have you Double Checked All Underbody wiring for fuel pump ,OPEN In Pink/blk tracer fuel power lead,also
Oil Sending unit on most GM Vehicles have the ability to turn OFF GROUND to Fuel Pump Relay as a Proyection Against LOW OIL Pressure in engine.

Fuel Cutoff Mode
The PCM cuts OFF fuel from the fuel injectors when the following conditions are met in order to protect the powertrain from damage and improve driveability:
  • The ignition is OFF. This prevents engine run-on.
  • The ignition is ON but there is no ignition reference signal. This prevents flooding or backfiring.
  • The engine speed is too high, above red line.
  • The vehicle speed is too high, above rated tire speed.
  • During an extended, high speed, closed throttle coast down-This reduces emissions and increases engine braking.
  • During extended deceleration, in order to prevent damage to the catalytic converters
