Don't replace anything else until we are sure. As far as the problem, if the check engine light hasn't come on, chances are it isn't an electrical issue. Check to make sure the fuel pressure is within spec, the regulator is working, and check for vacuum leaks to start. Keep in mind, it has a lot of miles and it could be many things causing the issue. If fuel pressure is good, you have good spark, there are no vacuum leaks, then check engine compression. Also, have you ever cleaned the fuel injectors?
