That doesnt mean squat!!! I had a ez go bad, thought it was the pressure sensor, that was the code it threw, sounded just like that truck, ended up being a conector bent in the plug on the ez.

 

Also wyocat, if rail pressure comes up, go ahead and plug the fca back in while at idol, if its the fca it will start running rough again

 

what are my chances i smoked a hole or piston? injector i can live with

 

If you unplug the fca the RP will go to max(over 23kpsi)Do not let it run but for long enough to see if the RP will go that high and then kill it or you might be needing a rail relief valve as well!

 

I dont think u have a hole in your piston...if you did the truck would be DUMPING white smoke like no other!!!

 

can you start truck with fca unplugged? or do you just start it unplug see what happens? i have my rail capped also

 

i unplugged my fca and replugged it in my truck starts runs a little lopey not bad at all and i get a p0192 cod fuel pressure sensor voltage too low

 

I'd say you need a new sensor.........what did the rail pressure read with the FCA unplugged? Still low?????

 

Unplug the fca and get in the truck and start it.The RP should go well over 20kpsi.Just make sure to shut it off quickly if it does.If it doesn't go high(rp)then you need to be looking at the fca or the RP sendor.

 

awesome thanks guys ill have an update shortly. i was so happy when i started it earlier and it wasnt nearly as bad it put my mind at ease about no scored hole hopefully. it sucks i leave to vegas tomorrow to turn the big 21!! but ill have an update later

 

ok guys i plugged in my rail pressure gaugee reads zero...with fca plugged in and with it unplugged...no heres the catcher with fca unplugged smoke is white on start up than black when revving with fca plugged in smoke is white/blue than black/white...

You either need to gamble on buying a RP sensor or go to the dealer and hook a DRB to it.It only takes a couple of minutes.Plug the DRB to the OBD port and crank truck.It will show what the ecm is calling for,what the RP sensor is reading and control voltage to the fca.Real quick to determine what is amiss with your truck.Good luck with what ever course of action you take.

 

i have a rail pressure sensor on its way so we'll see if that fixes it. that smoke color somethin i should worry about? you think it can be anything worse than injectors?

 

Your smoke just looks kinda white in the video.Thats the way mine did when it was screwed up.My problem just ended up being electrical connection.Did you ever get any dielectric grease?Check all the pins in the connector visually for any signs of corrosion or bent pins.
