Hi,
I have a 1992 190E that wont start unless I poor fuel in the intake. Then it idles only
It has been sitting quite a while. I changed the fuel filter and have fresh fuel in the tank and lines. I cracked the fuel line to let the air out at the distribution manifold for the injectors. I seem to have plenty of pressure.

I removed the cold start injector to inspect it while I cranked the engine over. I turned the key full off/on position about 10 times and only saw a mist of fuel 3 times. The mist only lasted 1/2 second or so.

Anybody have any suggestions?
Thank you
