do you need your ol cousin to come check this thang out for ya. Na hope you get some info, i know i get aggravated quick to.

 

How old is the fuel? Does it have water in it?

What is your fuel pressure at the throttle body?
Do you have good spark?
Plugged fuel filter? (Gummed up from sitting?)
Got mice/rodents in the exhaust pipe?
Intake pipes clean of obstruction?

My buddy had a grand prix... found out chipmunks had packed both mufflers with acorns. Started it up and was shooting acorns out the exhaust. Kinda neat...smelled like roasted nuts.

 

well therenomufflers it true dualsstright pipes...i think its the fliter...there an new pump in there...so would you think i could just take the old one off n let all the gas in side of it run out n put a new fliter on n put new gas in it,n change the oil cus its needing changed its turning brown....
