I have a 93 xcab 3.0 my issue is the truck at random just runs like crap cutting out,sometimes feels like its running on 3 cyl. I have replaced the fuel filter new plugs cap rotor button ran injector cleaner through it a cpl times..i have no check engine light coming on..I have not replaced the fuel pump becuz i am under the assumption that when a fuel pump goes bad it just goes..now i did have a hole in the filler neck and found dirt laying inside of it that has since been fixed i do have a leak in the tank..the dirt is the reason y i changed the fuel filter..any help or suggestions would be greatly appreciated!! thanks Ron

You can check if it IS running on 3 cylinders by pulling the plug wires one at a time.
If you have a cylinder not performing, pull the plug and look at it. If it's wet, you've got a spark problem (bad wires, etc.) If it's dry, some of the crap in the fuel tank may have gotten as far as an injector (there is a filter inside the injector which could be blocked, and if the crud got past that filter it could be clogging the pintle. All bad.)
Injectors can be cleaned/service for not-too-much money. But first you have to get them out.

Are you sure there are no codes stored? The light can be off but still store codes in the ecu.
I would do a plug wire pull and see if you hear a difference then pull plugs again.
Then maybe find an injector cleaning place near you and get your injectors cleaned. Or pull em out and send them to witch hunter. Hes a guy online and many people like him.
Its weird how it runs fine then just drops out?? Does it sputter ir just sound a little odd and go slow?
