ok. First i had 2 faults p0205 and p0202 a number 2 and a numer 5 misfire. I found that the harness was rubbing on the upper intake. Not to mention I opened the hood and a rat jumped out about the size of a wiennie dog. Anyhow, I replaced the harness and fault disappeared. Now I have 2 new faults:p2018 fuel rail pressure too high and p2016 fuel rail psi malfunction fuel flow below minimum. I then replaced fuel filter and low pressure sensor, with no luck. I did notice the sound of air when I removed low pressure sensor. On start up I dpo notice fuel pressure below spec and then above specified? I am now leaning towards fuel pressure solenoid but want more proof... thanks for your time guys.
