1991 560SEL Intermittent Crank - No Start

I have a 1991 560SEL that has a no start condition that I am struggling with to diagnose and any advice would be appreciated. Car will start and drive (very minimal throttle response though) and then stall and will crank but not restart. This happened for about a week and now it will not start at all, just cranks over. Replaced the fuel pump relay, no change in condition. Before going further, I removed the cover from the fuel pump relay and pushed the contact while having someone crank... 1991 560SEL Intermittent Crank - No Start
