Hyundai - Sonata :: 2007 - Does Timing Chain Tensioner Affect Oil Pump

My son's 2007 Hyundai Sonata had an engine noise that was eventually diagnosed as bad timing chain tensioners. However, one Hyundai dealer repeatedly denied the problem, so it was 8 months before another Hyundai dealer admitted it and changed the tensioners. A couple of months later, the engine light and oil light were on and he was told he needed a new oil pump. By this time, the warranty had expired and he had to pay for the new oil pump and eventually a new engine. My question is this: Could the failure of the oil pump have had anything to do with the timing chain tensioner problem?
