First quick check to do is make sure your fuel cap is tight. A loose fuel cap will set an EVAP code and turn the service engine light on.
Next, do you leave the engine on while you are refueling? If so, that can also trigger and EVAP code.
If the above is true, it will take "3" cold starts for the light to clear after the problem above was fixed.

If none of the above are true, take your vehicle to your local Auto Zone or Advance Auto and ask them to scan your vehicle for trouble codes, write the codes down and respond back. We can go from there.
Good luck,

Dont drive a car with the light flashing. A flashing check engine light means that something is really wrong and you can damage the engine if you drive it.

Bought my 1994 Blazer used last month. Last night engaged 4-wheel for snow driving for the first time. Now I need to get it back into 2-wheel and don't know how to go back! Can you help? Thanks!

Try with the vehicle in neutral, There may be a button on the shifter that has to be pressed and then pull the shifter back into 2 wheel. Let me know if that works.

I have a 2001 chevy blazer. Everything is in good shape except the body. I want to get another body and transfer the my engine and transmission.

Look around the want ad's, there are lots of Blazer and Jimmy's for $500.00 with drive train problems with great body's. Keep in mind though with the cost of the drive train transfer, you may be better off on replacing the whole blazer with a newer one.

My 02 blazer will not pull any codes up

Need to check the fuses in the fuse panel. Make sure your fuse to the ECM or any other functions are in working order and there is no damage to the ECM docking post. You can try resetting the ECM by turning the ignition key to the on position and "enhine not running" and pull the fuse to the ECM ut for 30 seconds and place it back in. Once the fuse is placed back in you should hear the fuel pump working energizing the fuel line and start the engine. the engine may stall, but let it. Just restart the engine, the ECM is just relearning the engine and drive train. So go for a test drive and all DTC codes will have been erased, so any new check engine light will be new issues that needs to be addressed. good luck

Chevy Blazer 4 x 4 and Engine Light Problems

To your problem with the air bag, I was driving an 07 GMC Sierra 1500 that was doing the same thing. Next thing the charges went on the seat belt tensioners, luckily I was parked because the belts gave me a pretty violent **** back. Turns out the SDM was corroded and caused the action, and there was no reason the air bags didn't deploy as well other than pure luck. I would say get it checked by GM, you don't want to mess around with safety systems. You can visually inspect the integrity of the SDM, it's located under the driver's seat, unfortunately I think the seat has to be removed to see it. Mine had a calcium like build up all over the external casing.

Does anyone know of a problem with 01 chevy blazer fuel pumps? i am on my 5th one in 3 years. the first 3 times i put in airtec fuel pumps. they never lasted more than a few months. then i bought a delphi....

This is beginning to look like a pervasive problem not unique to your vehicle. It would be interesting to learn exactly what failed inside the pumps you changed. I don't have any good answers yet but I would make a direct ground connection from the battery to the pump harness to eliminate any possibility of overheating of the pump motor from a poor ground, and see if it helps any. Also check all pump connections before you install it.

When the service engine light is on. The service engine light checks all the sensor in the vehicle with the engine running . The light will come on when any of the sensor are not responding to the computer in the car. The computer is monitoring the sensor constantly to give the engine the best performance in all kinds of driving conditions. The engine will have to go to a repair shop . The repair shop will try and get codes out of the computer to pin point the sensor failure or engine performance failure.

So in conclusion , I would take the vehicle to a local mechanic that can give you a warranty of at least 6 months 6 thousand miles.

Good luck
