P0190 code helpp

[imblown-ru]

i had p0190 pop up tonight when i was leaving a parking lot at low speeds. Is this the sensor that sits on top of the fuel rail? I had the code before when i was on the dyno, and it was a rubber gasket inside the fuel can that holds the pump. Anyone know what it could be? thanks

yeah thats a code relating to the fuel rail presure sensor.

check fuel presure manually then compare it to the live data from the pcm for the rail presure.

should datalogging give it to me? or do i need to hook up the guage?

look at the datalogging live and hook up a mechanical fuel presure guage. compare the two

should they match? or how will i know if somethings wrong? i think i know what it is. its the top of the fuel can where the plastic gas lines leave the can. when dynospeed was fixing it, the guy cracked the plastic and superglued it. i figured it would give out....this blows. how much am i gonna have to replace to get this right though? the whole fuel can or can i buy it in parts?
