The truck has actually been sitting for over a year and a half but has been started every so often to keep working on things or further diagnose different problems. But, now, it was last started about 4-6 months ago. I read a post that I can't seem to find about maybe spraying something in each cylinder if its been sitting a while. Is there anything that should be done to prime the motor before starting it such as spraying something to lubricate each cylinder? Thanks!
