I have a 93 190E 6cyl that will not start--unless I pour gas down the air inlet--it will run just fine as long as I keep pouring the gas. It has good fuel pressure to the fuel distributor. However, the only injector line that fuel is coming out of is the cold start injector. I know this because I pulled all the injector lines off the distributor and no fuel out of any of them. I have tried researching potential issues for 2 days and can't seem to find much. Any ideas or suggestions? Thanks
