another no start problem
So I have yet another no start issue my truck is a 2006 f250 I have replaced in the last six months 6 incjtors all the dumby plugs and both standpipes and the ICP. Stopped at the gas station today cam e out and the truck won't start. I don't have my gauge with me so I don't know what numbers I am puttion out. My question is will a ballon test help me to figure out if I have a bad injector o ring and if so which side its on. Also will an air test tell me if my o ring is bad? Thanks for the help guys

So if I am understanding right I do the bubble test determine which side is the problem. Remove all but one of the plugs crank it no bubbles install the next plug crank it once I see bubbles after that installing a plug that is the bad injector. Move to confirm no other ones are bad

So after a long day waiting on tow truck first truck that came out was not big enough to take my truck. Well I final get home I do the bubble test and no bubbles. So I do an air test I hearbair coming out of the passenger side valve cover I then applied 12 v to the IPR to command it to close and I still hear air coming out of the passenger valve cover. OK cool I know where to start but I also hear a hissing coming from the fuel filter cover. Is that hiss something to be concerned with? My next step is to pull the valve cover and then do another air test. I am pretty sure o know which injector is leaking the first one closeest to the front of the truck. I think that's the last one on the passenger side to replace.

I don't see how you could get air in the fuel side while doing an air test on the HPO system, but you can get air coming back through the HPOP and into the HPO reservoir which is normally heard through the oil filter housing. When performing an air test you should listen for air through the oil filter housing and both valve covers.

When you pull the valve cover and do an air test again, pay attention to the tops of the injector seals and nipple cup seals.

So after a little checking my IPR seems a little low at 66% I am reading I should be at closer to the 80s. Could this be my no start problem and why I am hearin g air from the pasaanger side valve cover

So I found the it leak it was a stand pipe I replaced about a month ago. Guess I will never buy another dorman product. But now the truck still is taking a bit of time to crank over and I am showing code p2284 would that indicate that my IPR is going out?? What else could I be looking at.
