Is anyone able to help with the workshop manual or part of that explains the correct sequence for replacing the injector pump on this. I know it’s the keyless Delphi pump to lock up before removing but can’t find any info on where to set the engine. 2010 4CX is the year and machine. I know the crank locks with a pin at TDC but believe you have another on the camshaft for pump timing. Many thanks in advance as seriously desperate😢
