I had an overheating problem that has now lead to a fuel issue. My late model A-4 has been runnnig great for the past 12 months (since I bought the boat, a 1976 Columbia 8.7 with orignal A-4). Recently it began to overheat. I removed the thermostat and it needed cleaning, along with the housing. I cleaned both and flushed the head and exhaust manifold; in doing so I removed and reinstalled the alternator and starter to get better access. I've ordered a new thermostat as it was old, and new housing as it was corroded.
However, after flushing head and exhaust manifold, and reinstalling alternator and starter, and without thermostat (new one hasn't arrived yet), the engine wont start. Cranks perfect but no go. I removed the spark plugs and all cynders are bone dry, no fuel. I drained the sediment bowl and float chamber (manual pump), all appear good as there was little water or contaminants and the manual fuel pump primes system when main passage plug removed.
I must be missing something obvious. Fuel and eletrical system all ran well before I flushed the cooling system. What happened? Any ideas or suggestions?
