190E/2.6/Lost power while driving

Hello:

I have a 190E 2.6 with 127K miles on it. Today while accelarating to merge into traffic on I93, the car sputtered, lost power, and failed on me. All the dash lights came on and a puff of white smoke came shot up behind me. Tried starting it back up and it would turn over, a poping sound would come from the rear of it but it would not start. Eventually had it towed to a inde shop who is going to take a look at it tomorrow.

After searching the forum, the fuel pump seems to be the likely suspect but I am not sure and would love to hear your ideas about what could be causing this.

FYI, I changed the oil (10WD-40) and swapped out the motor mounts this past Saturday. And, on Friday, had to clean the idle control valve and lubed it with WD40 to correct a realllyyy high idle problem that reared its ugly head then. Oh, and added a K&N filter to replace the OEM.

Any Ideas?

Thanks.

Update

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?

Thanks,
