| Post subject: | X3 Huynai Excel Problems - EFI help |
Looking for some general EFI guidance as I know next to nothing about fuel injection. My gf's car broke down today - x3 excel Tried my carby based truble shooting to no avail. Baisically, no blown fuses, when u turn on check engine light is illuminated Has spark to plugs, nice fat jolt visible w screwdriver in plug So all I can think is fuel. Only problem is I dunno what controls fuel. Does anyone know where fuel is controlled in an excel?? The other problem is that I could be completely wrong about the fuel ting... Any help??? Cheers, JOn |

Listen for an electric fuel pump pumping when you first turn the key. If no sound at first turn of the key, its probably the fuel pump, or an electrical problem causing no signal to the fuel pump. If the fuel pump operates, it should run with spark. |

If your girlfriend has a habit of driving with less than a 1/4 of a tank of fuel - Then it's likely the fuel pump has burnt out. May not be the case, but it can be an explanation if it is. |

Crank angle sensor? these were replace a bit when i worked at Hyundai parts many years ago. Cam position sensor? possibly fuel pump. |

if the check engine light is on, you might be able to pull error codes and find out why it's upset it'll point to sensor failure so hopefully you only have to replace one or two things rather than a process of elimination |

Thanks for the suggestions guys, it was the timing belt, really should have picked that up, man I really am a noob.  The engine is an interference motor and the head will be kaput  On the bright side the mech who diagnosed it got my RB30 180B going so its no big loss at all
