Hey everyone I just started getting code 125 today on my 2014 isx15. Im stuck over here in Brunswick ga about to try to make it to kw savannah in the morning . The problem I am having it runs fine then dies . I hook up insite and get code 0125intake manifold 1 pressure sensor. With this being bad cause code 0755 as well. Everything is new on the fuel side, new pump, plungers , backflow valve etc. It just started it at 1 pm today. What are the symptoms . I was giving it fuel backing in and it died had to hook up insite clear the codes. Im still learning this but got my wrenches . Thanks a bunch
