i have alot of starting trouble i have 300,249.7 miles this very moment the treuck was given to me. it also might be the stock spark plugs (wich im changing) i no its not the oil but its dirty.1-8-4-3-6-5-7-2}>
my guess would be that the truck was given to you and it has over 300,000 miles on it. happy wrenching and replacing to you.
im 13 it was giving to me by my grandpa it has a 305 it has a quadrajet carb and i think its the reason.
