Fuel delivery / power loss w111
Hi all, I have begun fixing all the new issues the 1965 220SE sedan that I recently bought. Lately when I have been driving on the highway and the fuel is nearing half full the car starts to sputter like it is being starved of fuel.
This has happened twice. I then go and fill the tank and the car seems to run fine again. The first time the tank was down 7 gals, the second time only 5.5 gals.
Once it starts then I can be in any gear at high rpms and the lost of power occurs. Let off on the accelerator a bit and the problem stops.
Also, I am having trouble starting the car. It happened twice right after I filled the tank when the loss of power occurred. I am not sure but then the other two times I couldn't start it I was parked on an incline where the front of the car was elevated. Not sure if that is related. But the not starting only began after the loss of power issue popped up. It turns over fine, just doesn't catch.
If I wait a couple minutes, the car has started again, so far. Today it was mid 90ís and the car didnít start a couple more times. But then started after waiting a minute or two.
Not very familiar with fuel injection yet. Does this sound like maybe the cylinder filter below the main fuel pump may be clogged? I have the two port fuel pump going into 6 injectors. Could the pump be weak? Tonight I checked inside the tank. It was spotless and no debris around the bottom gas screen.
I am also hearing a clicking sound that my mechanic said was the solenoid on the fuel pump. I believe it clicks after about 3 seconds whether the car starts or not. But if I try to start the car too soon I wonít hear the clicking noise unless I wait about 30 seconds before starting it again. Donít know if that is relevant.
I have not ever had a sucking sound when removing the gas cap either.
Thanks much for any help.
