Hard starting?

Welcome to 2CarPros. First to verify the engine, you have 2.2L and 5 cylinder listed. The 2.2L diesel should be a 4 cylinder if the service information is correct with the 5 cylinder being a 3.2L. However, being a diesel about the only things that can cause hot starting issues are fuel quality and pressure. Unless it's a low battery causing the engine to turn over slow. I would start by taking a sample of the fuel from the tank and having it tested to see how good it really is. To measure the lift pump and high pressure pump running pressures takes special equipment as the high pressure side is around 1790 bar.
