After all the mucking around I have finally got my patrol running . Pulled another injector pump off my old engine . Hooked it up and spun it with a drill, it was constantly pumping fuel even without ignition or powered . Thought somethings not right there . Got my hands on another pump tested it, all ok working as it should . Fitted it to car today and I’m back up and running . Morale of the story bench check your pumps before hand . After 3 pump failures I was still searching for something else . Just goes to show how **** these pumps are . Buy new or make sure you test them before install!
