Rail pressure should be in the thousands. Around 5,000 at idle and up in to the mid to high 20,000's at WOT.am i running out of fuel. cant tell with the rail pressure on the sct. At idle it says 40 and under full load it go up to 170. I checked fuel press to the high pres pump was at 4 psi.
Do tour egt's also climb fast when this happens? If so your probably running out of air especially since it's smoking bad.Or,I guess you could have a turbo going.Not to sure on that thoughThe restriction gauge has not moved. The boost will go up to about 44 or so and slowly back down. when it does this black smoke starts to come.
