Could a bad lifter cause an inline 6 to have trouble turning over when it is trying to start on the cylinder with the failing lifter? My theory is yes as the compression on the exhaust stroke could be going nowhere and causing the engine to not turn over. Or it's the 7 year old starter , but I did check the battery an it is fine. So let's recap my jeep has a failing lifter it sometimes won't start and costs a small fortune to enjoy, sound familiar! Any way I was just thinking out loud , has anybody else had anything like this happen, or could it even happen?
