2000 7.3 Ford Ambulance smoking and no power
My name is Marcelo Tassara and I'm from Chile. I'm having the following problem with my powerstroke:
About a month, the ambulance was working with no troubles but suddenly the engine went dead. We found that the external electric fuel pump was not working due to no voltage at the wires (we test the pump outside and ran ok) This pump is located near the diesel tank on the outside (p/n: 9C407). As I had no idea about where was located the relay that controls the pump (assuming it was not working) we made a direct connection to the battery and the problem was solved. It rans for about a month and one day the engines stalls with no power, you were able to stand on the gas pedal but it wont run more than 10mph and the engine wont rev up. Also it started smoking like an old steam train (black/gray smoke).
No codes showing at the ford dealer, the told me that they have tried everything, even reprograming the ECU and nothing. Today I've tried disconnecting what I think is the MAP sensor (located on the engine bay up at the left, a small box with a hose and a connector) and it went a lot better but still smoking) Also we found that there's a heavy oil leak from just one of the sides of the TURBO pipes that runs from the exhaust to the turbo.
Please, I NEED HELP with this matter as the ambulance MUST return back to service.
