1981 Mercedes 380 SLC new engine wont run above idle
Hello! I have recently purchased a 1981 380slc. It was DOA, with a locked up motor. I bought a 380se shortblock motor with redone heads and dual row timing chain. I have done my best to route the vacuum lines using a schematic from this forum. The car will run at idle, only whith the cold start injector energized. I have replaced the fuel distributor, no difference, fuel pump and componants, no difference, I am jumping the voltage overload relay (new one on order) there was no power to the ecu/idle control, that was the culprit. When I jump the fuel pump and press down on the air flow sensor I get fuel out of all distributor outlets. Last night I had it idleing smoothly with the CSV jumped, but this moring it was only running on the pass side of engine. It's got to be a fuel delivery issue- I have NOT replaced the WUR, also the vacuum line from the pressure regulator is going the the air cleaner hose vacuum connection. I have not replaced the pressure reg. The air injection valve seems to work as well. I was going to check for vacuum leaks this morning, but thats when it started running on only one side..pulled the front plug it was dry. In addition I'm using a manifold off a later 380, that has holes in the top, where as the original has caps on these holes. Everything els is the same. This car is kicking my butt! Anyone?
