My 190 E will not start. I checked and have good spark, but no fuel to the injectors when I removed a hard fuel line. Possible fuel pump? Where is the pump located (possibly 2 in line pumps) and what does it take to replace them? Do I have to replace both of them?

Pumps are in the rear. However check your Over voltage protection relay and fuel pump relay first.

Its a good idea to replace both pumps, if one is weak then the other will just work harder.....so might as well....

I agree. You will find both of these behind a false wall behind the battery.
OVP and fuel pump relay.

in this case all the idications are to Fuel or OVP relay. The fuel pumps, preferably both should only be replaced after checking / testing the above relays and if the tests indicate a faulty pump.
