You said the coil had spark. How did you check that? Did you check spar at coil or the end of a spark plug wire?

i took the boot of one spark plug wire and held it to the coil turn over motor and healthy spark was visible , i then lifted the boot from the center tower turn over. and the spark was more orange. weird thing is that it was starting fine before. computer fry? new distributor ? im really stumped however im not a professional

Not necessarily. Have you checked for fuel Pressure. Just cause pumps doesn't mean you have fuel pressure. Very common on those for the fuel pressure regulator.

Just cause fuel pump turns on doesn't mean you got fuel pressure.

If pump turns on and you have spark then your computer is fine. Sounds like it's starving for fuel.

okay so ill check for fuel pressure and get back at you guys ,i just dont understand how suddenly something went wroung is it possible for things to start failing after plugs wire cap and rotor are replaced?

Yeah still sounds like fuel pressure issue. I would Not throw parts at it. Check the fuel pressure. Does it have multi port or throttle body? If throttle body, take breather off and check injector pulse when cranking the engine for fuel. Hopefully it's just a clogged filter rather then the fuel pressure regulator. Both are easy to fix, just the filter is cheaper. Fuel pressure regulator is located just before your fuel rail. Looks like a metal accord with a small rubber hose on top of it. Good luck and give us feedback please if that's the problem.

when breather is off. after cranking i can smell fuel and see that the tbi is wet under each injector im going to tory red and filter couse i have a lil extra money get back to yall later in the day

i would like to add that my fuel gauge was acting pretty sparatic when truck was running and was only really reading the correct amout of feul in tank when driving at higher speeds 50 70 km.
