I'm running out of ideas.....still starting hard!
#12
so when its doing the hard start it is below 1500psi while it is only cranking then when it gets to 1500psi it starts?

would it throw a code if it was a crank sensor, and where is that located?

take a look at where your fuel lines support clamps that hold the fuel line to the frame.loosen each one and see if you have a pin hole in the line.If you have tried everything else you got nothing to lose.no joke this happen to me i worked for two day till i found the pin hole buy loosening the clamp a small stream of fuel started running down the line.I you have gone through all other checks you are getting air somewhere for sure.be sure to rub the clamped area with steel wool this will make the leak show its self quicker.hope this helps

i ran it today and did not see any leaks, what do you mean about connecting tubes, are you talking about the blue clamps, or injector tubes? Beacuase i just got injector tube yesterday, just waiting on the injectors should be here friday.

I just want to let everyone know that after a year of chasing this hard start issue its finally fixed. I bit the bullet and replaced all 6 injectors and injection tubes, had the exhuast valves adjusted and its running like its 2004 again. It fires right up after one crank and its never been this quiet under the hood. Thanks for everyone help. I have learned a lot about the CR fuel system.

just read today its always the injectors, they have excessive return basically the internal relief in the injector bypasses more than it should so technically it has a fuel leak, you just cant see it without seperating the pump bypass from the injector return. about 700ml running for 60 secs is normal pump return, and hardly no fuel starting and usually anything more than 160 ml in 60 secs running from injectors is too much so the pump and fca work double time to overcome the leak. no codes is normal but if you pop a little ether it will start, spike rail pressure then level out. number one cause for leaking internally is changing fuel filters every time truck loses power, not every other oil change like you should. it takes a lot of fuel filters to overcome $3000 worth of parts and labor to replace. just saying. fyi if you get a p000f or the poof code thats when you look at the overflow valve. its blowing open under a load. ive never had one leak without the code, and ive put in a thousand injectors. but i hope you at least went on line to get injectors, not the dealer. bc all of ours are remans and still cost and arm and a leg
