Ok, going to try to make this short as possible but Im looking for some advice. So within the last few days my car has started to sputter when I get into the throttle and i noticed that as soon as i get on the gas (to accel.. or have fun) the fuel pressure starts to drop very fast (like 20psi and lower) so i instatly stopped driving hard and just babied it because idling or EASY accel it will stay like normal around 40psi.
But i had forgot my Aeroforce guages will display pump duty wel I went into it and come to find out they are maxing out (95-100% all the time) And ive been popping code PO190.
I have already replaced the FRPS and fuel filter and it did nothing.
I am starting to think its an electrical problem somewhere and heres why, I noticed yesterday (again this started hapening about 3 days ago) that when i fired the car up first thing in the morning pump duty was about 45%, fp was perfect, but i gave it a little gas and it shot up to 90% duty and stayed there.
Well i was driving the car to the parts store to grab a fuel filter and i made a real slow sharp turn and i noticed my duty dropped to like 45% and I got on it about half throttle and it was perfect, pressure rasied a few psi like normal and it was great for about 15 seconds and then started screwing up again.
But i was on an empty road and if i weaved back in forth kinda hard / fast the duty was dropping into the 60s???
Sorry if this is confusing, just looking for some help, im wondering if i should drop the tank and look for anything?
Also, the fuel system is stock cobra injectors, pprv delete, cobra tank, dual svt focus pumps.
