2003 f250 6.0 loss of power on acceleration rough idle
Ok truck started running rough like it was missing and had no real acceleration the turbo was spooling but it barely got up to speed but it never stalled just really slow getting up to speed . Checked for codes with my SCT no codes. Took it to steelership they ran a diagnostic test this is what they reported,
Replace 3 injectors, found three injectors dropping out to -40-/-50 on power balance and fuel pressure is low.
Replace fuel pump and harness (found 3 injectors dropping out to -40-/-50 on power balance and fuel pressure is low.)
Replace icp sensor and connector ( found icp voltage reading towards low spec 0.18v possible icp sensor biased.
Power balance test found injectors 2,4,5 were dropping.
Fuel pressure flow test found fuel pressure 45/46 psi with valve open.
Ficim voltage is 54.5 volts.
So I replaced the icp sensor and the pig tail truck runs a lot smoother and starts very easy no rough idle. But still no power on acceleration. My question is if fuel pressure is low wouldn't it be low to all the injectors instead of just 3?
Would it be a big deal if I replaced my fuel pump with a Oem fuel pump for early 2003 6.0 because it had a fuel heater in it or should I get a newer model year pump with a wiring adapter that eliminates the plug for the fuel heater?
Any help or advice would be greatly appreciated. I can't afford new injectors and the fuel pump at the same time so would you do the three injectors or fuel pump first? Thanks for any help
