Hi my brothers VN turns over but it wont start. He has a habbit of driving around on empty so I was thinking some gunk may have blocked the fuel line/ fuel filter. I cant see the fuel filter either where is it on these cars? It has new plugs and they are all firing, so must be a fuel problem? Anyone had this happen before? I would appreciate some advice and maybe your thoughts as to what else it could be? Cheers

| Its auto, I dont think its the starter moter because it cranks over very well. I'll have a look see if I can hear the fuel pump. But I don't think thats it, any other ideas? And also where is the fuel filter on VN's ? I have never owned a holden myself and I cant see anything even resembeling a fuel filter. Cheers |

Hi
Fuel filter is under the back of the car near the tank on the righthand side. |

Trizo, that isn't where the problem is going to be, it's cranking, so the starter/flywheel isn't the issue here. It's either not getting a spark, or it's not getting enough fuel to kick over properly.
Test the coil packs,leads and plugs to make sure they are all in good order, check the crank angle sensor (if it's died then you won't be getting any spark) and check the fuel pressure. I know you said that all the plugs were in good nick, but if you haven't already done so, spark test them, if you already have, well done.
Something that may also be worth looking at is the earth straps to the engine, if they have come loose/off then you wouldn't be able to start it.
Check all the fuses over too, just in case you've blown the injector fuse, which brings me to my next suggestion: the injectors...if the car is run around close to empty all the time, it's possible that the fuel filter is clogged, it's also possible that there's a whole heap of crud in the injectors too...make sure they work properly as well.
After that, the fuel pressure regulator, maybe the idle air control valve...we'll work it out whatever it is. |

Nope, never had it happen to me, just spent long enough with my head in a wiring diagram to know what controls what. :)
Doesn't matter how many cylinders an engine has, all 4-stroke engines work on the same principles, and they all require the same things: air, fuel, spark
So long as it has all of those something will burn, take out one and it will not work properly, simple as that. Now...unless something truely horrendous has happened to the inlet manifold it should be getting enough air, so I'm ignoring that bit, fuel, really the only things that can go wrong with fuel is the pump and the injectors. Even WITH a dead fuel pump enough fuel gets in to have it idle (like crap) for a few seconds. Injectors are easy to test. Last of all is the spark, spark power, spark timing and spark quality are all ELECTRICAL, so it's just a case of working through the electrical systems to see what is causing the problem.
Believe it or not, quite a lot of the stuff I answer with hasn't happened directly to me, it's either been mates or just logic that tells me how to fix it ;) Seems to be working alright for everyone though, so I'm happy to keep running with it. |
