Mitsubishi Repair: 1993 eclipse no fire, fuel pressure regulator, fuel pump filter

Question
I have a 93 eclpipse and I have replaced many parts including the fuel pump,filter,air filter,plugs wires,battery fuel pressure regulator,pcv valve and now I don't any fire to the the plugs. Right before I changed the battery It was not starting all the time. It might start and the if you shut if off it would not start. If you let it set it might start for you. It also losses power if you you drive it ob the interstate for very long. So when after I changed the battery it started a couple of times and now it won't at all. I checked for  spark at the spark plugs and its not getting any. If you can help I would appreciate it.

Answer
Denny,
You should have your car's computer inspected.  Read this article for further information:

If the ECU is damaged or malfunctioning, it will cause sporatic problems very similar to the symptoms you're currently experiencing.  Have your mechanic pull the ECU and visually inspect it for damage.
Good luck!
