I have a 88 190e that will only start when I prime it (and run at high revs.) I have good spark and good pressure to the fuel distributor. However, I don't think there is pressure at the injectors. I have replaced the full fuel injection system and am still having the same problem. Are there any modules or computers that control the injectors that I may be able to replace. Any hints one what to try will be greatly appreciated.

thanks
