My 1998 Accord EX V6 is having problems starting on sunny days. Sometimes it'll start. Sometimes it'll try to start for a second and then die. Feels like its not getting fuel. It'll just crank and not start the engine after that. I would have to wait a while before it'll start. In the morning, it starts up fine. Looking through some of the threads and FAQ, it sounds like a problem with the Main Fuel PGM-FI Relay. Has anyone experienced this problem on their Accord? If its the Main Fuel PGM-FI Relay, can I get one of those from any car part shop or only from Honda? Oh, I also received a P0578 error code when I plugged in a OBD reader. Not sure if its caused by the bad Main Fuel PGM-FI Relay.
