I've got 120000 miles on my 2003 and i believe i have more than 1 leaking injector. I had #4 replaced at a dealer after having thrie assurance that this was the cause of my "no start' issue. The did the return test and got 280ml back. the capped off that injector and the truck fired up. so that was $1000 . well its been about two weeks and we're starting to get back to the same scenario. Long cranks and hard starts. damn thing left me on a boat ramp trying to pull out boat and wouldnt start. So do i need the whole injector or can i just gat nozzles. thanks in advance. And the shop isnt getting this work
