Hello can nyone help me.. I recently bought 1999 2.3 308d with the hope of converting it, when i collected it it had 3/4 tank of fuel everything running well . a couple of weeks latter and a few trips it was on under a 1/4 it seemed to run fine for 1/2 a mile then stop, it would take a lot of cranking over but then start and the same again stop.. got it to a garage who thought it might have been a crankshaft sensor but the diognistic machine shows no faults. i have noticed that when its running and i rev the engine i can see air in the fuel line which go between the filter and the pump . also when it stops i've checked the fuel filter and the fuel level in the filter is only80% to the top . . ive changed the fuel and air filter .. any ideas ?? cheers Neil. also if anyone knows a good mechanic in cornwall, as i've had no luck finding anyone who will even look at it..
