280 stalling , ovp & fuel pump relay location

[johnjbaby]

First time here glad to find this site, I have owned my 94 C280 for about 4 months love the car until lately, will just stall out of the blue, I have loss of accelleration first, asr light comes on , and about five second later it dies than won't retart for about five minutes, after that sometimes asr light comes on and stays on, car seems to stall more and more frequently now, just spent $600 having air mass sensor replaced, didn't help, mechanic than told me I should spray slider linkage maybe sticking, or may need to be replaced, said that was big bucks also said could be because of brand of gasoline (mobil) I used, have been reading threads and think I need to check ovp & fuel pump relays, where are they located on my car, in trunk or up front. thanks in advance for response
