billy_o Posted August 31, 2020 Share Posted August 31, 2020 hey guys got Econoline in shop / starts when cold 6.0 was in for no start just about month ago had new harness installed by another tech he also replaced 2 injectors because the connectors were broken and silconed to hold harness in place / was running but now it don't start when hot . check icp seen it was only building just over 200 psi when hot / removed ipr seen some dirt filings in screen so I replace ipr and installed new pump / install stand pipes updated ones / also changed the oil and installed oem oil filter with oem oil cup / took it for a spin got engine hot and still have issue decided to start from beginning test the base oil pressure notice base pressure is at 75 psi ran the engine till it was hot and the oil pressure was still at 70.75 psi at idle removed oil regulator at front cover and replaced /still seeing oil pressure high . little confused on this because Im thinking this is a restriction that's poss to high pressure pump to not build enough pressure to start / any thoughts Quote Link to comment Share on other sites More sharing options...
mchan68 Posted August 31, 2020 Share Posted August 31, 2020 Were the dummy rail plugs replaced with the updated ones too, when you replaced the standpipes? Quote Link to comment Share on other sites More sharing options...

mchan68 Posted August 31, 2020 Share Posted August 31, 2020 Was the no-start hot a pre-existing concern before the previous tech did the work, or after? If after, I would recheck the tops of the injectors for nicked o-rings on the injectors. I can appreciate on an E-Series it may be difficult to finesse the oil rail on and off when doing injectors, making it all the more likely to nick those O-rings. Sounds like an air test would be beneficial to pinpoint the source as well. Quote Link to comment Share on other sites More sharing options...
forddieseldoctor Posted August 31, 2020 Share Posted August 31, 2020 I had one that had the icp sensor plug on the left oil rail was loose and blew the o-ring out and had a long crank after hot soak. Quote Link to comment Share on other sites More sharing options...

forddieseldoctor Posted August 31, 2020 Share Posted August 31, 2020 Air test it from the port on the pump. You can listen through the oil filler and the breather box to try and determine side before you split it open. Quote Link to comment Share on other sites More sharing options...
