My 98 honda civic EX won't start... it cranks fine but the gauge cluster doesn't light up, so it means no power to the fuel pump power windows etc. I changed the main relay and it started and drove around fine but the next day, it wouldn't start again... I changed the relay once again but this time it didn't start. Spark plugs have been changed, checked I have a good ground connection, checked all fuses and all light up fine, fuel filter was recently replaced also. I'm thinking... ECU? Or its fuse? Please help

The ignition switch is likely bad--check for wear, pitting, or melting. Here's how to replace it:

Easy job.

Thank you so much... the ignition switch was bad. I knew it was bad before but didn't change it because it looked complicated but it was the easiest job ever... you're tha man!

Good job. Thank you for the update.
