Have they read any fault codes from the computer? If so, find out what they are and post them here. There's no guarantee that the new sensors are good, but it's unlikely they would fail so soon. Likewise for the fuel pump. If the pump runs, it could still be defective. Testing fuel pressure will tell you for sure if it's the problem. Unless the car has been in a flood or the engine washed with a very high pressure hose, I'm not sure about the moisture idea. There's always the possibility that a connector or a controller has moisture in it but, again, checking fault codes will be the first place to start to see where the problem might be. F'rinstance, an indicated problem with the crank angle sensor may mean a bad sensor or a problem in its connecting circuit.
