Re: 2002 CHEVY S-10 CHECK ENGINE LIGHT
YOU NEED TO HAVE SOMEONE READ THE CODES. SOME PARTS HOUSES (ADVANCE AUTO AND AUTO ZONE) WILL DO THIS FREE OF CHARGE. ONCE THEY TELL YOU WHAT THE CODES ARE YOU WILL HAVE TO FIX THAT PROBLEM BEFORE THE LIGHT STAYS OUT. YOU CAN RESET IT BY DISCONNECTING THE BATTERY FOR A COUPLE MINUTES, BUT THE LIGHT WILL KEEP COMING BACK ON UNTIL THE VECHILE IS REPAIRED

www.topix.com > California > San Diego County > Oceanside Dec 23, 2011 - 2003 Chevy Trailblazer-CHECK ENGINE LIGHT AND REDUCEDENGINE POWER ... The reduced engine power ligth comes on and I lose power. ...Next, the fan clutch failed -- which is when he did an "above and beyond" .... yesterday I have not replaced anything bc they have told me nothing is wrong.
Check battery and see if it can be fully charged. If there is an indicator on the battery it should be green or measure the voltage with the engine off and see if it is close to 12Vdc. If the battery tests good there could be a problem with the electrical wiring or a bad device that draws current when the car is off. Glove box light gould be on, trunk light stays on etc...
If the light is on, there there is a code stored. If you cannot extract it, you may need different equipment. You can't simply erase the code without fixing what caused it to come on in the first place. it will just come right back on.
Is the check engine light lighting up on the dashboard, when you turn the ignition key to on? If not then your ecu is in need of repair since it is not sending power to the coil and probably also not to the injectors also.

I think your car has a timing chain. There are a thousand things that can turn that light on. Have a shop ck it for trouble codes and that will give a direction on what to do next. Keep out af any chain store operation. If you cant find a good independent garage go to the dealer.
