Subject: Starting Problem
Question:

I am working on a 1995 Eclipse that will not run. The original problem was loss of fire to one cylinder. We changed the coil pack, which caused that cylinder to fire, but then when it would start it would back fire. Once it would finally start it would run terribly rough. We brought it to the dealership and when they tried to work on it, it would not start at all.
We then brought it home and I pulled the front of the motor down because it seemed to me that it may be a timing issue. It was out a little, fixed that and it still won't start.
I'm at a loss. Kind of leaning toward either the camshaft sensor, crank sensor, or the computer. Neither of which will be a cheap first try.
Please help. 
Answer: Cyril,
If you can, find out from the dealership exactly what they looked at when they had it. They may have already tested some of the sensors. If your crank or camshaft sensors was malfunctioning, your check engine light would mostly have come on.

I'd also lean towards having the computer checked out. Read this article for some related information:

Though you have a '95 model, there's still a chance some of the older capacitors may have made it into your ECU. Open up the ECU and inspect it for damage.
Good luck!
