Hi guys... been away for 2 weeks and now Stan the van won't start .. turns over but just won't start. Called Green Flag who started with easy start but yesterday same thing .. wont start .. he said could be fuel filter housing but my mechanic says no cos there's no sign of leakage .. he hit me going and I ran it around for an hour ., stopped n restated several times but over night again won't start.. any ideas? thank you ?

Do you hear a clicking noise from the fuel pump when you turn on the ignition lights? Don't turn over the engine, just switch on the ignition like you would if you were waiting for the heater plug light to go out and listen for the clicking noise.
