91 Ranger engine trouble.

I have a 91 Ranger 4.0 ohv. 5 speed manual. My truck died out and when I started it back up I noticed the motor hesitating. So I talked to a few people and they told me that it might be the timing chain. So on went a new chain assembly. The truck still does the same thing. So I pulled out and cleaned the injectors. Replaced the spark plugs and coil pack. Checked the fuel pressure and it was fine.

Any ideas as to what can be the problem?
