  If the starter rotates, but the AirMan Inverter engine doesn't start, there could be several reasons: * The fuel filter might be clogged, requiring disassembly, cleaning, and replacement. * The controller might be malfunctioning, so check the fuse. * There might be no diesel fuel oil, so replenish the fuel. * There might be air mixing in the fuel pipings, in this case you should bleed air.
