I have a 2000 Honda Accord EX with the 3L v6. I’ve had trouble starting for the last month ish. I’ve replaced the alternator, starter, battery, spark plugs, and ignition switch. When I put the key in and turn to on, most of the lights come on. Besides the key light, green light with key symbol in upper left, and the check engine light. If the car was running, when the key light and check engine light don’t come on the temperature gauge won’t move. On occasion when I put the key in, I can see everything light up, including key and check engine light, and I can hear something turn on, and it will start. It also has been having problems over heating and losing coolant. Ive replaced the coolant temperature sensor ( code from 02/10/2022) I can see coolant on top of the coolant reservoir but nothing on the ground. Is this a dealership can help or is it time to put her in the ground
