My sister is drivng or was driving what I think is an 89 mercedes with a diesel Im not sure if it is a turbo or not. And I have no idea about the engines or trannies in these cars. Well heres the problem It doesnt seem like the car is getting any gas so it wont start but it is turning over. So do these cars have carbs or are they fuel injected? Im guessing it is a fuel injected car so how can I check o see if the injectors are bad or clogged up? Also is it hard to change out the fuel pumps in these cars?
