I am working on an 85 190E that was sitting for a very long time. When I first got it it would not start at all and backfired through the intake. It was parked supposedly because it would not run (however many years ago). I did find the root cause of the backfiring and not running. The tab broke off the distributor rotor and the rotor was pointing the wrong way. As soon I fixed that the car will start and idle for roughly five seconds. I flushed the old fuel out of the car also. The cold start injector is not working either. I can start the car and keep it running with carb spray and even hold about 2500 rpm with short bursts of carb spray but as soon as the car is under its own power it will not run. I believe the root cause was the distributor rotor but before I condemn the fuel distributor is there any way to test and see if it's capable of delivering enough fuel to run the car? Any feedback or ideas would be greatly appreciated since I am not so familiar with this type of fuel injection.
