Did you disconnect the battery first? if not pull the negative with the key on.. car will die..then reconnect the negative with the key off.. then turn the key on wait 3-5 seconds for dash indicators to go out..all the factory presets should reset themselves..

    It isn't exactly clear what your symptoms are - are you saying the car won't start? or that the gauges don't work right, or what? Anyway, pulling a battery cable with the engine running sounds like a really bad idea. The alternator will keep systems energised anyway and it would probably keep running. If you reset the ECU, you may have to re-enter a safety code in the stereo?

    Many newer vechicles will no longer run on the alternator....I have a cadillac that won't.

SOURCE: My wifes Chevy Equinox DRL's are not coming on.

You need to buy a new DRL Resistor, about $85 dealer only of course. It's located on drivers side front wheel well I believe it was towards the front bumper. The part is ceramic, just change it out. Mine did the same exact thing and this will fix it!

SOURCE: I have 2007 chevy equinox.

Turn on your headlights and have someone watch them for you. turn the ignition key just as if you are going to start the vehicle. If all the lights stay just as bright throughout this procedure you probably have a vehicle with an ignition system fuse. The fuse may come in the form of fuse in the fuse panel or as a fusible link in the small red cable from the positive battery terminal. If it's in the fuse panel just replace it.(even if it looks okay, it may just be a fifty cent fix) If it's in the cable it then requires a test light and the ability to do a little electrical trouble shooting. It may come in the for of a sealed circuit breaker in the fuse box under the hood. Just check out your owners manual. If you don't have one and you have a parts store close by. You may even be lucky enough to have a parts store that sells Chilton manuals or something like it. If they aren't sealed in plastic you may find the info free by just browsing the pages in the store.

Does the 2005 chevy equinox LS have a chip in the ignition switch or can u change it ur self without having to take it to the dealer


yes you can change the key cylyder and lock out without having to reprogram the system. This is a very complicated type of job and I would suggest taking it to a professional shop.

If you replaced the ECM and didn't reprogram it. There's your problem. The ECM doesn't recognize the security code. And it will start and kill the vehicle three times before shutting down everything. IE.. starter, fuel.

Old post.
same here, there is only 2 paths (besides wild $$$ guessing)
1: yes, do scan it, if the tool goes dead (comms down) the ECU lost 12vdc power. (the CEL goes dead to , just key on, if no power to ECU/PCM.
2: or diagnose the no start.

what is flicker?, the dash lights come on key on to tell you power is ok and all things running them thinks they are happy,
some cars have immobilzers, and it does flicker at IMMO mode.
blocking you.
be specific on lights. what lights to what.
the operators guide is free, and shows each light.

Usually a sign of something draining the battery.
The machine test probably showed the battery could hold a charge and the alternator was charging the battery.
You may need to have someone check for a power drain.
When the key switch is off, there may be a weak short to ground or a relay or component that is using power.

You are throwing away money by replacing g parts that are likely just fine. Check for an ecu relay. My wife's 06 has an IPDM/ecu relay issue that will cause the vehicle to just die. It gets corrosion inside the contacts and cuts power to the computer. I had already purchased a spare for a couple dollars. Wife was close to home and car died, started back and was acting up. Swapped the relay in about 2 minutes and no issues since (several months now). Sometimes a small part can cause big problems. You can't just throw money at everything hoping to fix it. You need to do some research and troubleshooting.
