86 560SEL Too Much Fuel Pressure
I am starting this new thread in hopes to get more replies. I have a 560 that was gave to us by the father in law. I am starting to think he hates me being with his daughter. Just kidding. Anyways we parked our 560 and went to start it the next morning and it would not start. I have figured out that it is flooding get too much fuel to the cylinders. I have replaced the plugs, EHA valve and the fuel pressure regulator. If I take the line off the Fuel Distributor that goes to the regulator the car will start. I have checked the lines for kinks and even tried starting it with the fuel cap off. Could the fuel Distributor cause too much fuel pressure? Could a bad fuel pump cause too much fuel? I have checked the fuel pressure and get 100 psi at the main fuel line going into the fuel distrbutor. Shouldn't the regulator releive excess psi? I have heard the psi should be between 75- 85 psi? I am thinking of changing the fuel pump. I have changed one already because it was leaking. I was then going to have the fuel distrbutor rebuilt. Am I on the right track or should I start thinking the parts I got are bad? While we are at it does anyone know a good shop in UTAH. We took this car to Ken Garff for an alignment once and they quoted us $185 then called a couple of hours later and told us it was going to cost double that because we had custom after market rims. I argured this one with the tech and shop manager when I showed him that the rims were added from the original mercedes dealer and were mercedes wheels. We still had the paper work. They still wanted there money.
