I have a 1997 E320 with 110000 miles, I just changed the fuel pressure regulator because it had an internal leak also replaced the battery it was already about 4 years old, so after doing all that went to start the car and it would crank but no start,check the spark plugs for juice and they were ok so I figured that I might as well change the cam and crankshaft sensor since I have that many miles, did that and no start, next I did an ohmm check on all the injectors and they ohmmed out at 14.2 sao I did a manual injector triggering and they all worked so I check for the electrical impulse to the injectors with a noid light and bingo no electrical impulse to the injectors, so now I'm kind of lost because as far as know I'm at a dead end, can somebody help?
