I use 1998 Toyota sienna, the check light is not showing on the dashboard and the motor refused to start the electrician said the fault is from the brain box. Please help a brother.

There are literally hundreds of reasons why your car might not start. It's out of gas, the fuel pump failed, it has a dead battery, the ecm has failed, somone stole your starter. You have to provide details of you want real help.

The check engine light should illuminate for a few seconds with the key on and the engine off. If it doesn't the bulb is out. The check light will only stay on if the engine is running and the and there are diagnostic codes in memory or there is a current fault. If for instance, the engine cranks but won't start because the fuel pump has failed you will not get a check engine light because the fuel pump is not monitored by the ecm.

Best take the vehicle to a Toyota specialist...not just any mechanic. If you can't get a Toyota specialist you can go to www.requestmechanic.com and get connected to one. If you're within Lagos and it's environ.

Is the check light not suppose to show on the dashboard when the ignition is turned on.

Yes it suppose to show and if it's not I think it's electrician work
