Loosing prime / fuel engine dies when put in gear yet is belching black soot
Been fighting loss of top end and hard starting .
On land it starts and idles clean . put in water and it dies in gear like lack of fuel . pump primer it starts. Trying to idle out if it doesn´t die it´s putting out black soot . Try to run it gets to 2200 and compressor cuts out then back in as rpms drop and will keep doing that unless you pull back. boost pressure drops off when compressor kicks out to about 8lb. Turbo boost should be higher. During winter it was really hard start. Might take 15 tries to finally start .
We have installed new turbo. Cam ,crank, boost sensors checked timing. did injector tests. Replaced injectors even though old passes tests. Tried disconnecting mprop sol on pump so it would be max press. Evc read disconnect and set code. charge air cooler checked. Have run off Gerry can instead of tank and racor. Change fuelfilter housing and primer Assy. Have not had anyone put vodia on it . As no error messages.
It´s confusing , not enough fuel to run off idle , but black soot smoke from too much fuel ???
Any ideas. Thanks
