I have been going crazy working on my 93 300e 2.8l after having it overheat from a blown head gasket. Its probably easier to read the links at the bottom, but here is the quick run down. Car is way too hard to start, taking 30-90 seconds of cranking, and even then sometimes doesn't start. I'm not using it because of this problem, but really need it as we are surviving swapping out our other car to get around.

Replaced head gasket, injector o-rings, water pump, thermostat, temp sensor, OVP relay, CMP sensor, and checked everything twice including connection or vacuum line problems. Timing is good, both mechanically and with a timing light, injectors roughly tested, throttle opens when gas pedal depressed, exhaust comes out tailpipes with no out-of-the-ordinary odor. And once the car does start, runs smooth and fast, like there wasn't a thing in the world wrong. But this morning I got it started and took for a drive, came back, parked, turned it off, and same thing, still a pain to start. Checked codes and got a new one this morning.

Pin 14 Code 11 -
Fuel safety shut-off signal to engine control module
Closed throttle recognition signal to engine control module

Any ideas you would be AWESOME, as I have tried all the most common things, and this code is new to me.
