Not running 1987 190E

My 1987 190E 8 valve developed a miss at idling, then it progressed to a stutter when accelerating, and now the car just doesn't run at all. I have replaced the fuel pump, fuel filter, spark plugs, distributor cap and rotary button, and now the fuel distributor itself. It strats because of the cold start, but then it dies! There is no fuel coming thru the fuel distributor in the old one or the new (used) one. The compression on all 4 cylinders is from 159 to 172. The local Mercedes dealer wants $150.00 to diagnose the car, but I'm at the end of my wits and really thinking about selling the car to a junk yard! But I really love this car!! Please help!
