94 E320- Hard Start Problem- Solved!
Thought I'd give an update for the next guy who searches for a fix to this problem. As mentioned in original note my 124 started ok when cold, but after it warmed up it the car was hard to restart, long cranking time, stalling, etc. The Dealer replaced the OVP as seems to be the standard approach to this, however the problem remained. Based on info on this forum I put a new Fuel Pressure Regulator in the car this past weekend- Problem Solved. Car starts like new again. Cheers.
