Ok so I went to the store and it was fine then I went to start her to come home. I noticed a long start and then she started. Came back home three blocks away went to start 20 min later and nothing she cranks but will not start. I had a friend who I met on the forum come over and we got a dtc u1900 can't find nothing on this. My ICP is low around 347 or so I have no idea where to start ficm is at 48 volts and all fuses are good. We were thinking STC fittings and o rings for hpop went bad please all ideas welcome I need my truck ASAP........
