Computer car wont stay on when you start car no dash lights

S&M ?? Please clarify

Flash key fob

check for vacuum leaks,check battery and connection,fuel filter,stareter.

Yes it may be the wires are shorting or its actually the problem with instrument cluster.

Also get the vehicle scanned for any error codes stored in computer this will confirm whether is short circuit issue or actual problem:------

These will help.

Thanks.

could be a fuel filter

You have a relay sticking under the dash. If you do it yourself, go under there and start pulling relays until you find the one that makes the lights go out and that is probably the one that makes it start too.

there should be a single red light on the dash around the speedometer, if it dosent turn off after 5 seconds after you turn the car on it means the car dosent recgnoize the computer chip thats in your key... check that first, if the light stays on then your key is bad

battery is dead again let it charge longer then try it.
clean your cables and then have the alt and battery checked if they are both good then something is staying on like mine my brake lights stayed on once and killed the battery
good luck

sounds like a bad light switch....and that dash lights stay on drains battery
