Alright so I have a 03 duramax I am workin on, it literally has 10 miles on it. I am going to the local tech college and it donated from GM 7 years ago. From what I was told there was possibly a bad injector. For the past 6 years it has been threw handfuls of kids trying to get this thing running and nobody can. Last time they tried starting it they literally cranked and cranked to the point they almost burned the starter out. It has now been passed down to me. When I first worked on it today I pulled the oil drain pull and I would guess there was atleast 2 1/2 to 3 gallons of pure diesel fuel that came out before it went to a "chunky" oil. I am letting it drain over the weekend and going to refill it and see if I can get it to roll over. Is there any test I can do with a tech II or something I can command it to do with the tech II to make it fire? I have done a ton of injectors on these trucks before but never used a tech II when I had a no start and am looking for any help or info, before I go and put injectors in it. I should also note when I pulled the bleeder screw on the fuel filter housing I had fuel squirting out on the second pump. Any other test or suggetions are more then welcome, (I am hoping to get it running I could really use the A+
) Thanks for any help guys!
