Update: I called the mechanic this morning to find him having much difficulty with figuring out what the problem is. They told me that the fuel pumps are fine but that there is no power going to the fuel pump when the car is left on its own. They checked for the fuel pump relay and that they could not find one as the 93 190E 2.6 have a MAS unit instead. They also told me that they replaced this as their computer had told them that this was responsible for the issue --to no avail. Anyways they told me that they were going to do some more diag and that I should call them later.
I gave them a jingle early afternoon to find out that they were able to get fuel to the engine but it was backfiring. This led them to conclude that the ECU was bad so they are going to replace it.
How does this sound y'all?
