Honda Accord 2dr EX 6 cylinder 3.0. Intermittent starting issues whereby it didn't start a handful of times, within a 3-4 month timeframe. Then, it cranked over but no start at all for a couple of days Battery was new. Dash lights came on, including check engine light. The main relay had to be replaced but most mechanics didn't mention it. Much cheaper than starter, alternator, fuel pump, etc.
My light has been on for 5 years. my mechanic states it will cost $300 plus to fix and I have not had the repair. initially it was thought to be a leak in the gas line or fuel tank however the line has been checked and the gas tank was replaced as it rusted through. FYI I have NEVER had to replace a gas tank in my life and I have owned some old junkers in my time.
