New computer giving my 06' eclipse issues

My car broke down about 3 months ago. Its a 2006
Mitsubishi eclipse, automatic, I think rear wheel 4
cylinder. A mechanic of my dad's took it in his
shop. I don't think he knows what hes doing so I'm
trying to reach out for some suggestions with the
information he has given me. When my car broke
down I was driving to work not even going 30mph
and the gas let up and all the lights come on the
dash. Power steering went out. When my dad's
friend took it in his shop he said it was the
crankshaft censor. After he replaced that he said it
still wouldn't start so he said it was the computer.
Got a used computer but it wouldn't flash. So he
got a new one. Put it in and said the fuel injectors
wouldn't respond to the new computer. Waited a
week later and called and he said there was some
kind of wire pintch that it was saying it was
something else but what it said was the problem
actually wasn't. He checked all the wires and fixed
that issue but now says once again it's the fuel
injectors not responding. That's all the information
he has given me within the 3 months he's had it.
I'm not sure if that's enough information to give
suggestions on what it might be or what he might
need to try but I'm doing the best I can with 2
phone calls a week and having no way of going up
there. I NEED SUGGESTIONS TO TAKE TO THIS
GUY.
