Hi I am new to this so pls excuse any errors. I have Mercedes 220seb coupe mannual gearbox. Am in the process of restoring the same. The car is in India. The engine turns over fine. The fuel supply pump has been replace with a new unit. Plugs points condensor ignition coil and rotor are new. Injectors have been serviced. The car refuses to start on its own. When fuel is sprayed directly from the intake manifold the engine fires briefly. Have checked mostly everything recommended in the workshop mannual. Can someone pls help 🙏
