1986 Grand AM

Hello I just bought a 1986 Grand AM and when I try to start the car it fires and has a bit of a back fire but will not start.The person we bought it from said they had been driving it and parked it and when they went out to start it again it wouldn't start.Thank you for reading my problem.

the engize size would be helpful to better help you with the car problems. Until that I would look into the fuel and spark and make sure everything is fine. Also how long has the car been sitting since it last ran?!

Hello my grand am is a 3.0 V6 engin.The lady I bought the car from said it was running and she shut it off went into the house and came back out and tried to start it again and would not start.This was in the summer and hasn't started since.I went out side just know and took off all the spark plugs and put them back in the propper firing order and it started but it has a knock that seems to be comming from the back tapit cover.
