Hard Start stumper
I have a 2005 with a hard start after 70- 80 hours. Many times the truck gets shut down around 5 PM on a Friday and started back up on a Monday morning between 6 or 7 am and absolutly no problems say 60-65 hours but if have a 3 day weekend and say shut her down on thursday and attempt a restart on a Monday morning it takes a good 15 - 20 seconds of cranking it has done this twice in the last 4 months. Today same thing shut it done at noon on Thursday and tried starting it at 3 pm today same thing. Cranked it for about 8 seconds and then recycled 2 or 3 times like you would after changing a fuel filter and still done another 8 seconds and no start. The 3rd time it kicked over after about 5 seconds or so. No smoke and purred like a kitty when it did. Read enough on this great forum to say I most likely have a problem on the HP oil side but the time frame has got me stumped. Know I need to start digging but does anyone have any Ideas where to start? Seems like a HPOP problem would also show up with less time or the truck would run ruff or smoke when it did roll. Does it seem like a drain down of the HP oil circiut and the extra hours gets it to a critical point? If its a leak shouldn't it progressivally get worse and the time frame grow smaller. Cheezit and the techs have you ran into this one before? Any help would be appriciated to get me started.

this is a differnt concern then the one you left me a message about.
1) check batteries
2)check ficm voltage
3)moniter icp while cranking
4)check fuel pressure
5)check sync and ficm sync
that should get you started.

In the no-start thead, there is a way for you to check what HPO pressure you are getting during cranking (which can help determine if you have a HPO issue (like STC fitting, or leaking D rings, etc).

Thanks will get started on it. Batteries new and crank good even after the the 20 seconds crank time. Fuel pressure 68 psi. Been planning on replacing the STC fitting this summer but was saving the money for the EGR cooler delete to do at same time. Question does the HPOP also have a plug that some times leaks?

I have the sinister kit. Its very close to rcd's kit. As a matter of fact sinister stole the idea from them. Also first coast diesels make an intake kit.
I dont really advise what parts to get or not get though Thats not my function here. I will only really speak out if something really sucks.
