Won't start sometimes
I have a 2005 X and had an identical situation 2 years ago and found my ipr was the cause of my intermittent starting issue. During that ordeal I did head studs, egr delete, injectors, updated dummy plugs and stand pipes. Has run great since til 2 weeks ago.
Took a short 10 minute trip, shut the truck off, came back 10 minutes later and wouldn't start. Cranks fine, but no fire. Came back next morning and started fine. Drove home, shut off and would not start again. I'm thinking hpo leak somewhere. At this point I ordered Auto Enginuity scan tool.
While waiting for its arrival, I air tested the system. Rigged up ipr and it closed, air hiss went away. Repeated opening and closing ipr and could hear air hiss start and stop as the ipr was actuated. After leaving air hooked up, and ipr shut for 45 seconds, I heard a slight gurgle. This confirmed my hpo leak, I thought. Figured I would test with AE when it arrived to confirm the oil leak was causing the no start.
Now, I can't get the truck to not start. Drove down highway at wot and icp and icp desired were both at 3900 psi in stock setting, give or take. Would think if I had a bad enough oil leak to cause no start, that I would see a discrepancy in the icp values? Can anyone confirm this? So, I'm now playing the waiting game, hoping it screws up again soon. Anyone have any ideas? Truck runs fine and no cel, except glow plug, which I replaced yesterday. Could putting air to the system affected anything that would cause it to start ok now? I can't imagine my ipr is bad again.
