Hey. Scotty i have a 2001 escape v6 it has a bad fuel pump low pressure takes 2 to 3 cranks to start once it starts runs perfect but once engine is warm it misfire code p0351 in piston 1 can this be caused by the faulty fuel pump sending low pressure . need your help ..

generally low fuel pressure will not make just one cylinder misfire. More often warmed up misfires are internal engine damage, like valve problems

Could a chipped valve be valve be the cause

I have research a little and found out that a few escape owner have had similar problems and end with results of bad pcm . bad fuel pump and chipped valves mainly exhaust valve. What u think?? My piston 1 pressure is around 85..
