Car won't start?
Try this:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.
How about the starter.
Testimonial: "I have yet to have it tested I wanted to make sure that is what it could be I can jump the starter by touching the cylanoid with a flat head and it fires perfect"
SOURCE: Chevy Trailblazer 2003 ran the battery down now wont idle
try changing the air filter ,i had a problem ,at ilde in drive my trailblazer would stall, changed the air filter now it's not stalling and got my power back ,there is a secondary air pump that i have to change ,
not sure were it is ? still not running perfect but it's running better .and my service light is on too.
i got it put on scope ,it's the pump .
not sure if this helps ,but i'm start to run in to problems too,i have a 2004 trailblazer.
i like to do fix things myself ,i hope i can.it's the cost if you know what i mean.

First things first. Do you have a volt meter to check the battery voltage? What engine do you have?
Let me know.

I had this same problem with my 1997 Blazer, which required a fuel pump replacement as Nitrobike said. The sign to look for is when you get in the Blazer, turn your key forward to the accessory position, but not the start position. You should hear the fuel pump charging. It sounds like a hissing or whirring noise for about 2-3 seconds while it pumps fuel into the lines to prime the engine.
Fuel pump replacement isn't cheap, about $700-$1000.

Check your connections. did you run the fuel pump wiring under the drivers side door sash like GM did?.. if so check for nicks in the wire or bending or cracks.. this happens.. happened to me. check your fuel pressure. 40 dollar part at an auto store. If its below 59 PSI it wont work. And blazers are very intolerable to low fuel pressure. Also try taking the negative post off your battery for a little while and then putting it back on and if you can get it started again drive around (if its safe and running decent) for at least 30 minutes to get your car computer system acclimated to a new functioning part. Did you check the fuel filter?. rule of thumb when a pump goes change the filter its always the last thing people expect because we all jump to catastrophic engine failure at the first no start moment. lol.
Make sure that all your ducks are in get my drift.. Air oxygen fuel thats the mixture you need to check all those vital parts. before pulling your head off.

The starter motor on a car takes a lot of energy, you may be able to use the radio but not have enough power for the starter. You also might not be able to start it because the motor's starter or it's relay is bad. So here's what to do:
Check the connections on the battery, try loosening the connections and moving them around a bit, then tighten them down good.
Next go try to start it up again. If it still doesn't respond, turn your headlights on and see if they are still bright. If they are, then I would look into the starter or the starter relay.
The relay is in a box somewhere under your hood, possibly with some motor related fuses. Take the cover off and look at the under side of it. The cover should have a sticker displaying which relays do what. Now look for the air conditioner relay. Check to see if the air conditioner and starter relays have the same number printed or stamped on them. ONLY if the numbers mach, put the air conditioner relay in place of the starter relay, and try to start it again.
If you still get nothing, then it is either a bad starter or wire somewhere. On this car it may be a bit difficult to find and reach, but try to get to the starter on the bottom of the car. You can find pictures online of what it looks like if you are not sure. Play with the wires and knock on the starter with something hard like a rock or hammer. It doesn't take too much to do it, even a firm punch can do it, just don't break it. If this works then the starter is bad and needs serviced or replaced.
If there is still no response after this, there is nothing more you can do unless you are capable of taking things apart and checking the wiring. Good luck!
