Hello. How is everyone? I have an 02 Honda Accord EX 3.0 V6 coupe. It has extremely high miles on it 300,000 I recently had an issue with the green key light not coming on and it not starting. I also had an issue with the ignition lock leading me to have to take the tumblers out in order to get the key to even turn over. I put a main relay in which fixed my problem of the green key light, it now starts every time. I just put new ignition coils and also spark plugs in. Now it shows that it is overheating and the fans do not kick on until you turn the key off, very confusing to me. I also do not have heat anymore. I hope you can tell me what might have caused this and how I can fix it. Thank you.
