I recently finished changing timing chain and all rails on my 1988 560SEL with
256K . Engine turns but it doesn't start . If I push down accellerator all the
way it starts somewhat with a lot of sputtering and backfiring from within the
engine but dies immediately if I release gas pedal . I'm quite sure that I put
back everything correctly, even timing marks on distributor gear before closing
timing cover . I'm using new battery and car seems to be getting gas . I loosened fuel lines at injectors and main line going into fuel distributor . A moment of Triumph turned into disaster
