Does anyone know of any way to test the fuel injectors on an L322 4.4 TDV8 without removing them and having them bench tested. Can they be tested in situ?
Thanks. Rehab is for quitters!!!

Not other than relying on the pcm's ongoing checking that they are performing within spec and if out of spec then DTCs will be logged. The pcm checks that the crankshaft accelerates within an acceptable range when an injector is fired and tries to adjust the firing to get the acceleration within spec whilst keeping the adjustment factor within the acceptable range.
