Problems with Lumina ECM replacement

First, I have to mention that my mechanic replaced my fuel pump 2 months a go and ever since my fuel gauge doesn't work.

Latley the car started sputtering and stalling, so I got a diagnostic done at a GM dealership, they determined that my ECM was faulty. So I could not afford the kind of coin that they wanted so I had to depend on the mechanic at work. Here is the problem

Since the ECM has been replaced the car

  • does not stall or sputter any more :)
  • now my speedometer doesn't work :( * Seems like the car is starting in second gear :( * The inside of the car smells like gas fumes :( * The gas gauge still don't work

Can I please get some good advice. I want to know if you can program the ECM wrong, or install the wrong one etc... Or does my mechanic need to reread his repair manuals.

Sorry, The car is a 1993 3.1 ltr with 4 speed overdrive. Did I mention that the speedometer was working before the ECM replacement. I personally think that the mechanic made a mistake. Are both these gauges controlled by the ECM?

I long for the days of having a car without all of this computer stuff. I love technology, but not in cars :)

I just went for a drive and noticed that when I turn on my key the speedometer jumps a little so I guess that it atleast has power.

BTW. Thanks for the help so far
