My second hand Hyper 7 TQ2 has always been a pain to start so I fitted rotor starter cos i was sick of scuffing my knuckles with the pull start,now it will not start at all there are bubbles in the fuel line so i replaced fuel filter,fuel line and fuel tank! still getting air still will not start.Unfortunately this is not the only problem with this car when it was running i went through 5 glow plugs using 1ltr of fuel is there a connection?I'm so sick of this car the only thing left to change is the engine which i cant afford to do at the moment but what else could it be.HELP
