SOURCE: car wont start. turns over but wont stay running

your cars antitheft system is trying to prevent the car from being stolen so it is shutting it offf after it starts. go back over step by step you installation instructions make sure the ring around the ignition that comes with the remote starter is taped into the exact loacation it needs to be, or the cars own anti theft system will not notice it and will try to shut car off. its an anti theft feature. if this doesn't wotk you will not be able to use this remote starter. i ran into the same problem finally got it to work poperly.

Reset computer after battery change 03 trailblazer


Computer will reset after driving it around for a 15 min or so. Make sure your throttle body is clean, otherwise won't run correctly and possibly stall if your AC/Defroster is on. Cleaning it will solve this.

Need to reset the PCM on my 2003 Chevy Trailblazer .How do i do it?


Disconnect the NEGATIVE battery cable from the battery... Hold it or position to the POSITIVE battery cable for about 5 minutes. Also make sure you leave the key in the ON position (Do not have the engine running) and this will clear the memory on all computers/modules in the truck.

2004 Trailblazer - replaced blown speakers in back, now it won't start. Need to replace 2 more speakers - how can I do that without this happening again? Had to jump to get it started. How can...


This is just a guess but has happened to me before. The battery may be on the weak side and guessing you may have had the doors open for some time as well as the radio going for a while as well which could have pulled the battery down.

03 trailblazer 4.2 l code p0172 has no power


P0172 02 sensor is detecting that the system is running too rich. An 02 sensor that is starting to go out will pull this code, but the following will cause the 02 sensor to throw this code as well:

A few things to look at. 1st thing I'd do is clean your throttle body with the battery disconnected. Use sensor safe throttle body cleaner, about $4.

From there, I'd look at your upstream 02 sensor, located on the exhaust manifold on passenger side of engine, very easy. Try and stay away from Bosch if possible.

New fuel filter, clean or replace your MAF sensor located on top of engine next to firewall. Also, probably time to change your spark plugs. I recommend A/C Delco 41-103, will idle better than other brands.

My battery dies overnight on my 03 trailblazer, i can jumpstart it and runs fine and i shut it off and start back up and it runs, but when i leave it off overnight the battery dies down again.


Check all your connections at battery to make sure they are tight, and clean, but my guess is it will probably need to be replaced, unless you have a large current draw happening. Stop in to an Autoparts supplier, or your preferred repair shop and ask them to test your system, as in battery , and ask them to double check that there isn't a large draw when engine is shut off. Sounds like alternator is o.k. as it is charging battery, but battery isn't holding charge, and a quick test by knowledgeable technician will confirm whether it's battery, or something drawing it down. If you happen to have another good battery you can try for a day or 2, that will also tell you.
