I'm looking for a very good diesel mechanic and or electrician to figure out what is wrong with my 2004 EX 2.5 CRDI Sorento.
1. Engine tumbles but doesn't start.
2. Engine cuts while driving then goes back to problem 1.
3. Getting some white-ish / blue-ish smoke when starts up on mornings or if parked on a slant.
4. Getting black smoke when reving.
My main concerns are problems 1 & 2. I ran a diagnostic and the results showed the Rail Pressure Sensor was malfunctioning. I changed it but it didn't solve the problem. I changed the fuel pump and the primer on the top of the fuel filter but the problem still exists. Cleaned out the fuel line and no good results yet. Someone suggested it might be an electrical problem with the solenoid in the fuel pump or a part in the fuel tank itself (can't remember the name).
Can anyone help?
