I HAVE A '84 190E 2.3L. NEED TO KNOW IF ANYONE KNOWS THE SPECS FOR FUEL PRESSURE ON THESE VEHICLES. ITS BEEN SITTING FOR 2 YRS AND WONT START. I CLEANED THE FUEL TANK AND CHANGED THE FILTERS AND GET GAS GOING INTO THE FUEL MANIFOLD, BUT NOTHING COMES OUT OF THE INDIVIDUAL INJECTOR RAILS COMING OFF THE MANIFOLD. ANY HELP WOULD BE APPRECIATED. THANK YOU
