Mate start with the basics. Pull a plug lead off the spark plug, put a new plug in the lead and earth it to the engine some where. Get someone to Turn it over and see if ya have spark, the plugs could be worn out Have ya enought fuel pressure. Take to inlet pipe off the fuel filter and turn on ignition, fuel should come out pretty fast, if yes, put the inlet back on and take off the outlet. Pressure should be around the same. If not, fuel filter problem? If yes then possible sensor fault maybe. I don't think there is a fuse that would actually stop it from starting if it's turning over unless your ecu is toast. Air flow meters are soft on the type r's. I went true 3 on my one. They always started but hunted on idle and would cut out. Try the first two first. Any hassle text me 0404663398
