VN Won't Start

[endlesshysteria]

Gday Guys,

So here's the story. Borrowed the old man's VN while the VT was off the road and let her run out of fuel, that was my first issue. Got to the servo, got some fuel in and she started, beauty... Then drove about 20km's and she died, won't start at all.

Got her towed home and now sitting in the driveway until I get time to look at it, for example now :P What happens is that she turns over but will not fire at all! I do not suspect fuel pump as it primes for about 1 second when the ignition but still doesnt fire. Replaced fuel filter with no joy.

Have checked the leads and plugs and all looks ok, got try to replace the leads and plugs but dont suspect them as it seems fuel related, you know running out of fuel and all

Could there be anything else that could go wrong after running out of fuel? She was running fine after getting fuel in and then just died, could the fuel pump priming be a false positive?

I have checked for price of pumps and found they are pretty cheap, how hard to replace?

Cheers for any suggestions,
Hysteria.

id say make it prime several times if ya cant here the fuel returning to the tank id say ya have a air lock possibly also have ya checked the fuse under the bonnet my old vp race car would blow them every time it went dry

best way to tell is to take the fuel line of at the engine end feed it into a bottle and tun the key if it flows its the injectors if it dont its the pump

also an error code check will help

[endlesshysteria]

Cheers Rob. Have checked all fuses to do with fuel and ignitions and swapped them all out and still same issue. Could the airlock be from when I replaced the fuel filter? Should I take it out and refit?

If I had the gear for an error code check I would go through it but I dont.

Will try the line into the bottle tomorrow after work or Friday, if it is flowing through and is the injectors, is this a big job to fix? Can only assume so.

Cheers.

just a thought but when you ran dry you may have sucked up all crap from your tank so maybe check your fuel filter and injectors

[endlesshysteria]

That is what I was thinking in replacing the fuel filter, I have run a bottle of injector cleaner through it before and ended up having to replace the fuel pump as it died.

Any other way of cleaning injectors, or advice on what I did wrong last time? It was a few years ago when the VN was mine before donating it to the old man.

[rob drag racer]

not hard if its the pump if its the injectors it can be hard its possible that the fuel filter is full of air or even the wrong way around and i only say the wrong way around because its easy to do ive even done it crack the top hose out of the filter and go turn the car on stick ya head under the car if its driping it has presure and no air lock id consider looking there first and if ya going to refit it tonight wile your there ya might as well check for flow there i tend to soak mine in fuel before fitment so its guaranteed to flow the first time

[uzdvn]

sorry i dont know anyway to clean out the injectors the only thing is maybe the filter blocked up before letting to much crap through to block the injectors.

[endlesshysteria]

Top tips Rob, cheers. Will be checking tomorrow night, just got the fuel off me and dont feel like getting drenched for another night. I am sure the filter is in the correct way as I have read many threads where people have put them in the wrong way and made sure this wasn't

So basically to test, take the engine side hose off, see if fuel comes through, if not fuel pump, if so.... mechie Should I try injector cleaner if its the latter? Sorry for all the questions and cheers for the help!

[rob drag racer]

injector cleaner is a waist of time anytime it dose nothing the only way to get injectors clean is ultra sonically which meens pulling them out and sending them away theres some guys on eBay that do exchanges cheep

and yeh ya got it right just make sure ya test the flow first before getting to excited might just be an easy fuel pump change

[delcowizzid]

ide be checking for good spark as well i noticed you said you checked the leads and plugs but didnt mention if it had good spark.are the injectors ticking do they have power to them

[rob drag racer]

that's where i was headed next with injector pulse but didn't want to go there until we know if it has flowing fuel

[Zuicider]

or the obvious thing could be fowled fuel. water can leak into their tanks . you fill up drive around the corner and she dies. it will need a full flush if thats the case and if u have your reciet get them assholes to pay for it

[rob drag racer]

maybe but not common i dont have that issue 1 bonus to lpg lol either way lets see if theres flow

[endlesshysteria]

Cheers for the help guys. Will be taking the filter out tomorrow after checking for flow, soaking it in fuel before it goes back in though

Thanks for the tip about injector cleaner.

Sounds like the injectors are ticking and good spark, plugs only replaced 2 years ago and has been rarely driven since as old man has a work ute but now needs the commie back for some reason.

If its not fuel, i will take plugs out and possibly replace them to test that. Got some spare leads here from when I had the VT engine done, also the same for plugs.

As for water in the fuel, haven't heard of it before and trust the servo I always go to, besides don't have a receipt...

Dont like the sounds of getting injectors cleaned, wouldn't really be worth it. Car is worth about $2k these days, cheaper to buy a new one, but lets hope it aint that.

[endlesshysteria]

Checking the flow tomorrow (Thursday) night, will post how it goes.

Either way, will be testing the rest Friday as I have the day off work and dont finish til 7 tomorrow night so limited time to get things done.....

[Zuicider]

yer just a few problem places at my end, endless complaints about fuel in the water, must have had to fix 10 or so cars over the last 12 months

[delcowizzid]

if the filter is new theres no point taking it back out it wont block that fast even if its in backwards it will still go i just replaced someones filter been in for years was on backwards didnt effect the running of the engine at all.pull either the inlet or outlet line at the engine saves getting under the car at all.turn the key 5 or 6 times will fill the filter pretty quickly

[rob drag racer]

good luck and ya can get injectors done for less than 200$ a set delivered to ya door

that's not 100% true my filter has a anti flow back valve in it put it in the wrong way and it don't work

[delcowizzid]

is it an aftermarket flash filter stock VL-VS replacement filters dont have them at all the non return is in the fuel pump.

[rob drag racer]

mine is an after market one i couldn't tell ya the brand i got it cheep and its to suit a vn vp it has a ball bearing and spring in it so yeah either way there out there im not going to ague the toss i only know what i have

[rob drag racer]

how did ya go ?
