Ive recently removed the head of a tamd41, decoked it , lapped the valves, fitted new injectors, sleeves, rings etc. Also ive fitted a new turbo and cleaned the aftercooler and the heat exchanger. Ive put the cylinder head back on , complete with everything else and turbo.
The engine refuses to start. I need to run a starter/charger on it to even get it to turn over at a decent-ish speed. The 12v start battery is totally charged yet hardly turns it over. The valve clearances(0.40 mm) are perfect, the flywheel hole indicating tdc to confirm num1 cylinder etc. The engine is recieving fuel, the injectors sounds like they aren't firing properly. there seems to be air? somehow getting into the lines somewhere but when i bleed prefilter and use the lift pump, not much comes out. Any uncommon places to check for air etc ? Ive tried cracking all the pressure lines at the injectors, sometimes fuel sometimes air. Also why won't the engine turn on battery power when system fully charged? Ive tried another new starter, new battery (just incase) stop solenoid seems to be operating fine. The head was off for approximately ten days. im really running outta ideas and starting to lose my rag with it . any ideas greatly appreciated.
