Just to update i got my truck fixed i had a friend come help me and we did finally find i bad wire between pcm and frp sensor. And the bent pins was messing up my o2 sensor so for now it's fixed with no check engine lite

 

@Drew Hicks Thanks a $Million$ for reporting back. I would respectfully like to request - would you kindly post another Torque Pro reading of MFEM1 and MFEM2. Knowing WHAT you repaired and if those two 'bits' are cleared, it would help me verify / identify those MFEM flags in my database.

Thanks - F150Torqued.

 

Did your 79 reading change . Key on -not running , running fuel pressure ?

 

This is the reading after all is fixed

 

My fuel pressure reading also did change now it reads different its like 38 psi when running where I was just stuck on 78 no matter what

 

where was the wire that was bad? I am having the same issue. Mechanic said the PCM is not receiving signal from the FRPS but the sensor is new. Thanks.
