Hi, I live in Poland, and my car was imported from the USA. I like USA Ford and I've been driving these cars for about 8 years but I have a big problem: My car doesn't want to start. I replaced the fuel filter but unfortunately the fuel pump isn't working and my computer shows P1233 and P0191 codes. Could you help me?

P1233 Fuel Pump Driver Module Off Line. Here is the list of items that could be the problem:

Inertia fuel shutoff (IFS) switch needs to be reset.
Open FPDM ground circuit
Open circuit to FPDM PWR RLY
Open FPDM PWR circuit
Open or shorted FPM circuit (engine should start).

The most common problem usually failed FPDM. It is located under the spare tire. Here is a picture. Here in the USA, it is about a 100.00 part.
