After coupling replacement engine no longer starts

Hello all, now I’m a bit perplexed. I changed the clutch to my CDI year 2003 with 175,000 km. Today I had everything together again but the engine doesn’t start any more. I had it clocked for minutes. But it doesn’t make a sound. I checked all the cables and sit tight. A petrol line broke off during the dismantling and I bridged them with a hose and is also tight. If someone has a tip for me, please report thank you already in advance Mfg Rainer
