I've had my car for nearly 12 months (Fiesta 1.4 TDCI 2005) and it's never failed to start. I recently took it to the garage to have the fuel filter replaced. The following day my car started up for a few seconds then cut out, it then would not start. The garage have said it may have something to do with parking my car uphill on the drive and the fuel is draining back into the tank.
Any ideas on what could have caused this, as mentioned above, I had previously started it up on the drive for 12 months without a problem, could changing the fuel filter (or something in connection with this) have caused the problem.
