My car is not start when the key on to start the moter all light are become off, 2 days ago i used jamper the car is start but naw it is not start, what is the problem of this car?

possible fuel line leak get checked asap

have you had the BCM(body control module) checked for any service codes? it sounds like your BCM may be experiencing memory loss or failure.

Make sure battery has a full charge and battery connections all good. Voltage and ground are both important. You could use a test light on the fuses in the fuse box to check for voltage. Some fuses are hot all the time, some go hot with the key on.
You may have to check feed to and from ignition switch.

Take the battery cables off one by one and clean the inside of the clamps with sandpaper/emery cloth. do the post also, re-clamp and try again. Many times the inside of the cables become corroded and have enough contact to power the lights but when you try to start it there is not enough flow to turn the starter.

I belive they didn't reset the oil light timer. I belive the sequence is 1. key on (not acc with engine off)
2. step on the brake pedal 5 times within 10 seconds. 3. key off. 4. start car. 5. check if the light went out. you may have to try it a few times to get it.

the anti theft device is in the valet mode

hello,
from your opening key button, on the car key, its a black,folding key. keep the opening button pushed until a red light apears in front of the key side. then start the engine. Both lights on the inside rear view mirror will blink.
then is reset.
hope will work.

hi, this is just a reset issue. sometimes the CPU can become confused. the original warning that informed you about your gas cap is still in the cpu's memory. you will have to reset the cpu and, this will clear the warning. After the reset, it will stay off. chevy cpu's tend to do this from time to time.

Locate the ticking noise. It is a relay that has gone bad.

have you replaced the starter?
