1997 E300D Mercedes Sedan. I took the Injection Pump from a Turboed car and put it on my Non Turboed car. I did start it and it ran fine for 5 minutes. I am diagnosing it as leaking air. I've replace all the clear lines and o rings, my Question is: I'm guessing there is a 400 PSI difference between the Turbo and Non Turbo Injectors, I'm referring to the POP Pressure. I am getting unburnt fuel from the exaust. Would the Injectors Popping at a lower pressure than what the Injection Pump is rated at, cause my car to not start?
