[QUOTE="918evo, post: 3512982, member: 6001"] Coolant temp sensor, injectors bleeding while engine off, or blown HG(s) is where I would start. First check coolant temp sensor data and if that's ok. Might pull a plug after no-start condition and see if it's wet with fuel or use a borescope to look for coolant. I would run the injectors dry by removing the fuel pump fuse and let it sit overnight. Put the fuse back in and see if it fires up when cold. If there is a schrader valve, you could just release the fuel pressure. [/QUOTE]
