when the truck is cooler and running just fine and fuel pressure is fine i get the same return rate as when im having fuel pressure problems

Also reply for FCA it will go to full fuel as long as its below operating temp, as soon as its reached operating temp and you unplug it, doesnt make a difference, fuel pressure will not rise

Yes test was done while at operating temp

Sorry i got my spec off im getting 100ml for 1 minute of idle on injector return

Bone stock truck no programer

04 5.9 C engine code 305hp engine, truck has plenty of power till truck reaches 180 thats where high pressure fuel will no meet fuel setpoint, example setpoint is 12k only has 5-6k on pressure. Now list on everything done and test done, truck came in like this tested lift pump pressure only at 3...

Sorry i forgot i put my lift pump pressure gauge on average 12-13 psi at idle and not ever below 6 while driving, lift pump pressure hasnt dropped when rail pressure starts to drop,rail pressure stays good until coolant temp hits around 195-200 then pressure tanks

Earlier post with replaced fuel pressure relief valve (blow off valve) has been changed already

Yes it shows demand and actual and it cant match demand pressure

Yes p0087 fuel rail pressure low

yes also fuel rail and sensor and pressure relief replaced

Loss of power and watching pressure drop on my snap on verus scanner

2012 6.7 loss of fuel pressure after truck warms up. Sent injectors in had tested on 2 different benches one being a bosch bench passed,reinstalled with new injector feed tube all torqued to spec. Replaced cp3 (high pressure pump) with FCA,fuel filter and lift pump test done by volume and...

Truck has normal fuel pressure at idle and down the highway until the engine is at operating temp... Lift pump pressure stays the same as fuel pressure starts to drop,I retorqued the fuel injector lines to spec already, for example with scanner hooked up to truck down the road setpoint is 17k it...
