Archived injector nozzles

[CObst]

I put ATS 75 hp nozzles on my 03 3500 SO and now have a hard start problem how can I check injectors to see if they are leaking down? 1st I need to make sure it is a pressure problem and then can I check each one individually and lastly could it be a problem with something I did?I had no torque specs.

CObst -

Pull the dipstick and see if there's any diesel fuel in the crankcase. I installed a set of 95hp injectors in a 2004. 5. After noticing it was down on power we pulled the dipstick and the crankcase had 2 gallons of diesel in it. We changed oil and filter, pulled the valve cover, cranked the truck and put it in gear, raised the rpm's and you could see bubbles coming from around the base of the injector. We pulled the injector, changed out the body and the truck has been running fine ever since.

Hope this helps -John
