Got a Universal M4-30 on my 1989 C&C 34R. It has glow plugs and an electric fuel booster pump. It needs the glow plugs energized for a full minute before starting the engine when it's cold. I wait even longer when it's the first start of the season and the entire engine is cold. I'm pretty sure that's stated in the manual. You can feel each of the cylinders where the glow plugs are located, to check they are all working heating the cylinders. Ours usually starts on the first try if I have kept the glow plugs on long enough. The electric booster pump if you have one, makes a ticking sound (like a bomb timer) when we turn the key on. When the pump went bad, we were still able to start the engine and run her half speed, for hours until we fixed the bad ground and got the electric pump running again. An engine guy told me, "Rule of thumb is, don't try to start more than three times with the water intake open, as water may flood the lift muffler and back up into the engine." I think that's too cautious but be careful. You can try starting the engine with the intake valve closed, and risk damaging the water pump impellor, but they are cheap compared to other engine parts. You can open the valve once the engine starts. Good luck. Let us know what works. Chuck S
