Conflicting information about your engine.......

So I thought it was the fuel accumulator as many members had exactly the same problem and fixed it by replacing that part. (Maybe staying so many months out of use made matters worse).

I ordered everything and changed the fuel accumulator to brand new bosch unit plus a new fuel filter. Part of the procedure according to the manual is also to lift the sensor plate and it did indeed make the noise and -I think- fuel was flowing to injectors.

So gas in the car, brand new battery, brand new fuel acc. , brand new fuel filter next day I start the car and it starts with the first try without even needing an extra long turn on the key. Idles roughly but good I try to add some throttle through the hand control everything fine. So I have to move the car relatively quickly(because of the extreme noise/neighbours) so I don't give it proper time to 'warm' up and slowly starting backing out. Car stalls. Never started again. No matter what I tried a bit more throttle, a bit less throttle. leave it to cool. Nothing.

Fuel pump works. Fuel is coming to the engine, there is ignition/spark...hell it even run for a little bit but now engine dies the minute I stop cranking the key. I think...it feels like maybe has more fuel than it should? Like it gets flooded but could be wrong. There was some fuel(?) coming from the exhaust, plus slight white smoke after some attempts when I walked away from the car. Really can't understand what's happening...


Mythos,

Your car (chassis) is a '71 as you mentioned in your initial post. And subsequently installed an '81 SC CIS motor as shown in your pictures. I highlighted the section or information that does not make sense to me. Why would a hand throttle be used in a late SC engine? Did you use the older CIS components for the '81 SC? Keep us posted. Thanks.
