You need to check the MAP with the engine turning over. An open line will show atmospheric pressure while the engine is off and while the engine is trying to run.
You cna check the cam timing without removing the valve cover. You simply line up the holes in the timing gear with the parting line of the cam bearing caps.
We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind. - Stu Harmon
