I am planning on using an old Benz 300 to help me meet supply to some customers but. The issue the car is having is that it always enters 'half starting' especialluy in the mornings. Even after driving for sometime and I leave it for up to an hour and want to start it again, it does the same half starting. I have given it to different mechanics who have worked on the injector and the kick but it seems to occur after sometime.
Please I will like the experts here to help with some good solution to this problem. Thanks

Pls define "half starting"

Another sweet terminology learnt today

Lol. Half starting or hard starting. Check the fuel relay behind the battery.

Half starting or hard starting like someone mentioned, is when I start the car but it doesn't pick immediately. Sometimes it even runs down the battery.

Its working fine

what is working fine? The relay or the car. In most benz, they bridge the relay with wire. What does urs have? Relay or wire bridge. How does the car idle. Smooth or rough, high or low or swinging between high and low.

It has a wire bridge and it swings between high and low.

1.u have to buy a fuel relay and remove that wire bridge.
2. Under the air box in the engine bay(the round metal beside the engine), there is an idle control valve(has a socket and plug). Check to make sure it is plugged to that socket. I think it's a 2 pin socket. If it's not plugged, then plug it. If it is plugged, then u need a new idle control valve. Sorry I don't have pictures. Hope gazzuz helps.

V6 engine

I6 you mean. M/benz 300 never comes with V6

You can go ahead to get a proper fuel relay but you must replace ur fuel pump.

If symptoms persists, change ur entire injector unit which includes the IAC.

I think all Mercedes 300 have inline 6 cylinder engine.

Most of them especially here in Nigeria has been refitted with inline 4 cylinder engines. That was why I asked that question.

...I refitted mine with an I4 engine back in the days and I still used the car till date.
