    2004 5.7 Thunderbolt turns over but won't start

    Just got back from the boat. - removed fuel line to carb and inspected mesh filter, looks good. - put fuel line back on loosely and cranked it over and fuel came out, good as well - replaced the ignition coil because it looked bad and the plug wire broke off inside when trying to remove it...

    I changed the spark plugs yesterday because it was something simple and easy to write off as not the problem. It was not the problem. I took Friday off this week and will try the following: 1. Compression Test 2. If 1 passes.... Take the fuel line off the carb (or loosen it) and see if fuel is...

    2004 5.7 Thunderbolt turns over but won't start

    1. I did not have a clear jar to see if what was in the fuel. Poured it in a blue bucket. 200 litres was from September, 100 litres new from January 2. No it didn’t. Didn’t respond to it at all.

    Here are the sender and switch. Posting just to confirm that the threaded hole that looks pretty rusty, is fine and suppose to be empty.

    Small typo, OM675896. Not sure if that makes a difference but that’s what’s written in my book and there’s definitely 8 cylinders. Will confirm that number when I visit the boat today.

    Not positive that it’s a TB. OM665896 is the serial no.

    Constant alarm but motor running fine - 2004 5.7l raw water cooled Thunderbolt

    For context, my boat is moored in semi fresh water (tidal river next to the ocean) and hasn’t left the dock since September.
