[QUOTE="Superduty00, post: 1274201, member: 23054"] Ok so for starters I have. 2000 7.3 6speed no chip/tuner all relatively stock engine wise So the other day it randomly decided to crank/no start I finally got it started after cranking and cranking while holding down the pedal fired up and ran fine but starting problem continued on I thought for sure it would be ipr so I replaced it with a motorcraft one and same issue here is what I have found/tested so far Icp while cranking stays between 250-300 and dc% spikes to 64.5 Once it finally starts icp pressure is erratic jumping between 450-750 never staying steady long enough to get an accurate reading constantly jumping and dc% is about 16.5 once it warms up dc drops to 10.9 and icp pressure still bounces but doesn't get quite as high mayhe like 650 Has no ses light no dtc codes no codes on cct injectors passed buzz test truck stumbles if icp is unplugged when running hpop is full recent oil change and oil level is good injector o rings done in last 5000 miles Any ideas on where to go/what to check from here? And is It normal for icp pressure to jump around like that at idle? And btw all readings are from ae scan gauge Thanks in advance need to get the rig back on the road [/QUOTE]
