190E 2.3 mystic fuel pump and FPR problems
So hello all! I'm asking for help on my 190E and to start off I have to say that english is not my first language so bear with me 
So at first the car was leaking fuel from the pump so I had to take the whole bracket off and as you may know the philip screws were kinda useless, so I had to use some strenght to get the pump off. At the same time I changed the fuel filter because why, not thecar was having some very small misfire problem. Okay pump is no longer leaking and car is running fine despite the pumps sound is now bit louder. Couple months after that the FPR goes and I changed that and everything was fine, until couple month or two later the relay goes again. After that I thought that the old pump is going to die soon or for some reason its drawing more power than the relay can take so I changed the pump and the relay and the car is fine for about 3 months... Well couple days ago I was taking off from lights and the car just stalled, it felt weird because it's hard to stall this 190 atleast without trying. I tired to start it without any luck and then my gf and I pushed the car off the intersection and off course the pump doesn't turn on with ignition so naturally i take the relay off and connect the 7 and 8 and the pump doesn't turn on. Soooo the I'm pretty sure the pump is dead but what could cause these things, can it just be bad luck and the new pump was bad or what could it be. The car has been so problematic the whole time I've had it but I've always been optimistic and keep giving it a chance
Thanks to all for helping!
