any access to a scan tool to see codes and actual and desired fuel pressure when cranking it over ?
Customer: replied 6 months ago.
I had it at a gm dealer and they are playing a guessing game with it when I can get it to run fuel pressure is between 4200 to 4600 give or take
Expert:  Gary replied 6 months ago.
if this ran before the key to this problem is if its making enough fuel pressure when cranking it overdid they say it was or not ?
Customer: replied 6 months ago.
they told me it was going to cost 7 thousand dollars to replace 4 injectors that I just replace high pressure pump and check valve I had it towed back to my house and checked for codes and I got three of them but I am not sure if they are right because the batteries are almost dead

p0090
Customer: replied 6 months ago.
but I am not sure if it has to do with the dealership doing something to it
Expert:  Gary replied 6 months ago.
that 90 code is for the fuel rail pressure signal to the computerthat code will set if the fuel rail pressure is too low or too high or the wires from it are pinched to the computer or that sensor is badif you have any questions please ask as i do not get credit for my work until you rate me here at Justanswer
