[henatlbch]

I have a 1982 mb 380 sec i bought about 10 months ago it didn' t run when I bought it and the previous 2 owners couldn' t make it go on the first try it kicks hard enough to disengage the starter then nothing if you keep cranking and floor the pedal she seems to try to run like a car with a flooded carb i ve replaced the fuel distributor checked the cold start valve replaced fuel filters and lines and accumulator and pump any help would be appreciated I love the car and would love to actually drive it thanks
