my vk 6 cyl has been sitting in garage 4 a while and it always started but about 6 months ago i stated it and it was running rough making all sounds of noises and when you touch the excelerator and rev it the revs has trouble to get reving starts coughing splatering ect so i did not worry bout it as did not have time but now i wanna get it running i started it 3 times same problem but now it wont turn over at all
fuel pump is working checked that and it wants to start but just doesent1
what could the cause of this be
timming?
dizzy?
fuel injecters?
dont no alot about cars but if i have some indication to find the problem capable of doing it so i need your brains
its always had like a fuel problem like its running to rich as some smoke out of exaust but petrol not oil and some times you would start it and run smooth but others it would run rough high and low revs and cut out ect
your5 help would be preferd
Good chance the fuel has gone bad empty the tank, change the fuel filter and clean the injectors/carb which ever it is?
PERFORMANCE MODS- JTG Liquid injection, Under driven pulley, Pacemaker extractors, 3" X-force system, Cold air intake, MAF Less tune 267.9 RWKW'S

Yes I know, if you get anymore manly you are in danger of making yourself pregnant!
yer i would also drain the fuel out of the tank and drain the carby or clean the injectors. also wouldent hurt to cheak plugs or buy new spark plug leads?
first of all its a red engine fuel enjected 3.3 watever it is wth the big ugly top on it
have spark the enjecters are working fuses are all working fuel pump working could timing stop a car from starting????????????
any other things i can check 2 eliminate and how 2 check them cheers thanks
also changed the fuel filter and had not much petrol in it but put 40 buks new petrol in it.. wats the best way 2 clean injecters?
nah, itll be a timing issue. prolly a dud trigger in the dizzy. i dunno exactly what ignition systems these use, but it sounds like an intermittant HEI sender (if it was hei) go over the dizzy with a fine tooth comb. rotor button, cap, leads, plugs.
yeah i think it is the dissy or timming has new leads and spark plugs and def has spark
you tried putting a test light on it while it cranks to start? it doesnt need to be running to flash. at least you will know where your mark is.
reading back through again, its kinda strange that it still has spark but stopped working. maybe i am leaning towards what the other boys have said about fueling.
also have you checked/changed/cleaned air filter, mass air flow, throttle body etc?
mass air flow? how do i check dat?????????
got a new dizy cap and rotaer gonna fit that 2night n do timing so hopefully dat will fix it will be bak on hear 2 morro if it does not work lol cheers 4 all ur advise
ok new dizzy cap and rotar then put timing light on and moved dizzy had a few just kicks but nothing major then could not get any kick out of it after a while ???????/
any more suggestions can i run fuel straight through the fuel line instead of taking out the tank so just put the hose into say a bucket of fuel?? 2 c if it is dirty tank or fuel ..
you can smell petrol getting through the moter
i dont know how 2 check throttle body or vacume cheers
um, no i dont think so. the pressure for efi is pretty high.
im hoping someone can clarify this:
i dont know what kinda of MAF they use specifically. but its usually attached to the air filter box. after a while, tiny bits of dirt build up on it and can throw the readings. carby cleaner takes care of it, just spray it on liberally.
where was the mark? when you say "moved it a couple of clicks and couldnt get any kick out of it" do you mean it wouldnt crank over anymore? or the timing light stopped working?

in the middle of the bit that has lines on it
it wanted 2 crank over when u hit a certin spot then batt went dead then put new batt in it tried 2 find the sweet spot their was none no matter how hard i tried
also noticed were the injecters are their is a black cord wth a silver bit on the end looks like it should plug somewere but ther is no were i can c it to plug in is dat normal ? its just under throttle body at the front of the first injecter
im gonna pull the tank off and clean thgat wen i changes the fuel filter i pulled a metal cylinder off and wen i got a fuel filter it was the plastic one is that right also i just figured the upgraded
sorry bro would help if i new more about cars but u gotta strt some were and rather try fixit myself then call a mechanic and get charged dollars
thx 4 ur help
Firstly I recon it's a black 202 not a red even though the rocker cover and intake manifold are red it's the block that is black rather then blue or red. Iv got the same engine and had lots of trouble with it but just persist and you will find the problem! Ok I'd start with checking the plugs themselves take each one out and check they all working well! Then check you have pressure in the fuel rail by pressing the valve at the front of the fuel rail. Should squirt out a heap of fuel as it's under alot of pressure. Next take off one of the injector plugs and put an led in the plug itself turn the car over and the light should flash in a rhythmic pulse. If it doesn't take the led out and turn it around or put the legs in the opposite way cos LEDs only work with the power current going one way. If it lights up the injectors are working so if you have good spark and fuel it's prob ya timing. Oh and one last thing before I get to work is that plastic fuel filter is prob for a carby 202 the efi 202 which you have requires a high pressure fuel filter. The plastic one won't be good enough and prob restricting ya fuel supply so I'd def get the right one. Ok il be back on after work at say 9 tonight let me know how ya get on!
ok chers bud thx 4 ur info ill go get a fuel filter and sunday im gonna go over da whole car so ill keep u updated and find out more if needed cheers bud thx enjoy ur day
ok i think i ran into a problem cleaned tank 2 day lots of shit in it but i checked my spark plugs and got new ones to put in but i thinkk from previous owner threaded were u put them in as they wont screw in 2 wont grab wth the thread so wat do i do to get them in or do i have 2 replace that part of the engine?
so i think they r cross threaded
firstly, you are screwing into cast iron, so the likelyhood of threading it is quite low. secondly you obviously were able to get the old ones out, so i doubt itll be threaded, thirdly if it is threaded, start looking for a new cylinder head.
a couple of problems come to mind:
1. make sure that the wrench you are using to start the thread fits in the spark plug hole. there are two main sizes, cant remember what they are, 13/16th or something and 3/4 (maybe) the bigger one, plus your wrench in the smaller socket hole will not work. but i kinda think that these heads are the larger kind so move on to point 2
2. are you doing it up on the correct angle?
3 . are you turning it clockwise?
4. is the washer from the old sparkplug still in the hole?
Lol yea def don't recon the threads are the problem lol the plug thread would go before the cast iron cross threaded lol! Um other thing did ya get the right plugs? Might have the same looking plugs with dif thread gap...
hey guys my car is going i called a thread repair guy 150 buks was threaded first few cm and obviosly loosing compression as soon as the spark plug went in it fired so put a new set of spark plugs in while i was at it and running like a dream thx 4 ur help
