For those of you following I've been having starting issues off and on for a week and a half. I thought I fixed it by clocking the MAF but just now after work I started it and it died after 10 seconds. I clocked the MAF a little more and it started but just barely, it ran really rough and started giving a P0191 error code which I looked up and found it means a problem with fuel pressure. The car only has 36,000 KM on it, what's the most likely problem? It's still at work so I can't play with it much.

its a fuel rail pressure(FRP) sensor circuit( range or performance problem). stop and talk to a ford mech, maybe its related to fuel pump problems. a pretty common problem with these cars.
