[:@]i did a spark plug change today and now when i drive my 86 k10 for any amount of time stop and then go to restart it ..it wont start till i let it sit for almost an hour any help this is my only transportation and i need it to run when i want it to not when it wants to .[:@][:@]

did you set the gap properly If not then fuel will build up in there and cause it to be hard to start till the extra fuel evaporates.

next time try to start it with the trottle wide open.If it doe's start right away,it's like chevylane 2003 said.
