    fuel pump or injectors would not cause the speedo to stop working compleltly or the power to cut at exacly 50mph. blocked injectors or fuel pump would cause an affect thro all performace the car has no problem hitting the red line all the way to 50 just that the point it cuts but the speedo not working must be related in some way possible ecu connected,

SOURCE: fuel pump relay dropping out

Obvious solution might be to change the relay, however here's a suggestion. When you see the relay starting to fluctuate manually hold it in the closed position to see if car still cuts out. If it does you're more that likely looking at an ignition problem as the relay needs a signal from the ignition to let it know the engine is running. If it doesn't cut out try another relay first.

How do I rectify erratic needles and lights on Ford Mondeo dash?


Had this problem in a Lincoln. Only car that showed 45mph at a stoplight with brakes on. Odometer kept churning up miles as car stood still. Turned out that Alternator was shorted and although battery kept charge, the alternator case was losing 16 amps into body of car.

I even installed another digital dash. Take off the alternator and have it bench checked.

Mondeo wont start, makes a click sound when ignition is turned on


hi sounds like your starter motor has packed in with all the trying.. just quickly put your car in 5th gear and give it a rock this might release it if not then you gota replace it and as a must get your battery charged up so it has the correct cranking amps to turn the starter
