Holden/isuzu rodeo 2001 diesel 3.l litre 4wd starts rough idle stops … Checked fuel lines pump etc no action when press accelerator - thought maybe tps but codes say no problem … Any ideas
I’d guess it is a fuel problem of some sort. Either pump from the tank, or the high pressure injector pump. Before going down that path though, suggest to double check the tps. Usually that means measuring it’s resistance vs angle of the throttle valve.
