i CHANGED THE FUEL FILTER BUT NOW THE CAR WONT START. THE KEY SPINS THE MOTOR TO PRIMETHE FILTERBUT NO FUEL IS REACHING THE FILTER. I TRIED BACKFILLING THE SUPPLY PIPE BUT STILL NO LUCK.ANY IDEAS? THE CAR HAS ALWAYS STARTED FIRST TIME PRIOR TO THIS SO I SUSPECT AIR IS THE PROBLEM AS I LEFT IT UNCOUPLED FOR A TIME WHILST REPLACING THE RAD AND CONDENSOR.

 

Make sure the fuel lines on the filter are the correct way round! If they are, Keep cranking and it'll go. You may need to fill up the fuel filter with Diesel first though!
Remember, don't burn out your starter!!
