kia diesel no pressure in fuel system?

we have a 2003 kia sorento diesel which just cut out whilst towing a caravan at 60mph. no loss of power at any time, no smoking. been working perfectly. we can prime the system and it starts, but having used all the primed fuel it cuts out again. we've had new fuel injectors fitted but there is no pressure in the system. The garage says there is no internal fuel tank pump. theyve tried a different fuel pump but it dosent help. any suggestions. theres no engine management lights and its been hooked to a computer, just said the enjectors were no good which have been changed.

Yes finally today we have the car back... the problem ....
water ingress into the ecu.
ok so its beneath the front passenger seat yes. but in january when we bought the car the roof light was leaking, the front seat and foot well were swimming with water.
the roof light was repaired by kia and nothing else said.
the ecu has corroded and sent out error reports to the injectors which in turn have blown the ecu up.
final bill over £1389.00 uk and just over 4 weeks without a vehicle.
4 new injectors and a refubished ecu later, the problems fixed.

yes and it isnt the problem. if we take out one injector the car stays running but mis-fires. if all injectors are in there it wont run. it'll start when primed but after it has used all the fuel it wont keep going.
