So the other day at school i hooked the ford IDS scan tool up to my truck because it was misfiring and the check engine light was on. it gave me 6 different codes. all relating to fuel. cylinder #3 was misfiring and i was getting O2 codes and system too rich codes. i checked my fuel trims and they were -24% so its running extremely rich. i checked my fuel pressure and it was 75.5 psi. i was thinking it needs a fuel pump driver module but i wanted to see what you guys think? thanks!

 

Don't know about fuel problem but if you have a cylinder not firing you could have rich codes from the unburned fuel

 

75.5 psi?! I would think you would blow something at that pressure

 

fouled plug...maybe even a bad COP...the other codes are because of the #3 misfire...

 

75.5psi seems a bit high for your fuel pump, mine is putting out around 55 to 60 PSI and thats normal for a factory fuel pump.

 

Im thinking my pcm is bad. before i got it to communicate with the scan tool and it would run but now nothing is working and the battery is fully charged but now it wont communicate with my scan tool.
