That's a pretty big question with not very much information. First, I'd plug in a code scanner to figure out what the COMPUTER thinks is wrong. The computer is seldom wrong.
If the dash lights come on, but the engine won't start, check the starter. There could also be a problem with the fuel line or the spark plugs. If the engine turns over, but won't start, check all of the fuel sensors. If the motor has a clicking or buzzing sound, check the alternator.
check your fuel line.... and u might look at the oil and air filter too.
Your check engine light will not come on in the auxilary (accesory) position. It comes on when the key is in the on (run) position to check the warning lights just before you start the vehicle.
could be a bad crank sensor, it wont always set a code, ive had a few that dont. if you have a scope or scan tool, manually check that the sensor is good.
There's a solinoid in the transmission.Suggest to check that first. Turn on interior lights. Start engine. If the lights go out when the engine stalls, you have a bad ignition switch.
check the battery and connections/cables
No, leave the engine off to check the oil. When you start the engine it sucks all the oil out of the crankcase, so none will appear on the dipstick.
Maybe you need to check the oil The oil light will stay on until the engine starts. If the oil light was on when it was running and now it will not start then you may have internal engine damage. Take it to a professional.
Are you saying that all these lights stay on after you start the car? If so, you need to get the problems fixed that are causing the lights to stay lit. You have these problems. ABS-Anti-Lock Brake System problem. Check Engine- Emissions Controls Problem Trac- Traction control turned off Tire Pressure-Low Tire Pressure Security-?? Read your owners manual carefully.
FLIP same thing happen to me today. dash lights turned off and all of a sudden the whole car, now it wont start no lights on the dash not even a crank from the engine. so depressed :(
Underneath steering wheel check relay 100&103
Will it turn over? if yes then check for spark and fuel
