hi, i have a 1985 camaro z28 it starts and runs (poorly) and when given gas it bogs and studders where should i start

 

First has this car been sitting awhile or is this a daily driver? Seeing how you haven't given up much info I'll give you this. Start with a tune up and check your timing. let us know how that works.

 

im replacing the fuel pump, replaced the fuel filter, spark plug and wires, if i have to mess with timing i get help cause i have no clue about that. and it has been sitting for awhile

 

Before you replace the fuel pump do a fuel compression test first. That's alot of work to do and if the fuel pump is good then it's all for nothing. Take it to a car guy to check the timeing. Should only take a few minutes,
