I will check if it reads fuel pressure on the Fg when I get home. Never the less it does read fuel pressure when it is supported by the vehicle ECM. I'm not here to sell products but I can get them cheap if people want them. Back to the subject at hand. I think that the CReader will give you the info needed to narrow the low power fault down. Or you could buy an Xcal for $700 off a tuner and read your sensor outputs with that. Link to comment Share on other sites More sharing options...

How did you go with those checks in my earlier post? Link to comment Share on other sites More sharing options...
