the problem still persists...
« on: July 07, 2010, 07:45:29 pm »
rite my car hasnt been wanting to fire up, ive just changed dizzy cap, rotor arm, ignition leads and ignition coil, the plugs are three weeks old aswell. all parts are bosch or beru, leads are tdc from euro parts. the ignition timing has been set to g40 spec three weeks ago when remap chip was fitted, but was doing this before that anyway.
after all of this the problem still persists... when i did get it started up after many attempts it idled like shit, worse ive ever experienced, lumpy, revs up and down, whole car jogging (on idle) so what next??? could it be a sensor, or the hall sensor? please help! the gs driving me crazy!

Was doing it before the chip was fitted though Hayes!

What's your battery voltage like with the engine running? Is it any better if you leave it on a charger overnight?

Did the garage set the timing properly, i.e. with blue tem sender unplugged?

Could be hall sender, so if you've got access to a spare dizzy then try that.

Have you had the motor compression tested?

well yeah, they are easily damaged by static.  But if it was doing it before then, then presumably it's not the chip.  Give the things andy said a go.

Did the garage set the timing properly, i.e. with blue tem sender unplugged? - il ask tomorrow lol

Could be hall sender, so if you've got access to a spare dizzy then try that. - havnt got access to another one, but theyl test everything first

Have you had the motor compression tested? - il get it tested tomorrow

i just need some pointers and tips to help them, their not stupid just not g40 specialists lol

are the leads in the correct firing order?

yer leads were exactly the same as previous ones, mate from the garage came over and had a look also.

ok so went to take my car to the garage this morning and like usual it wasnt starting, when it did, it sounded like it was running on 1 cylinder, amazingly lumpy and as soon as i tryed moving it it cut out or just cut out on its own, i put the old dizzy cap and leads back on and like normal wouldnt start but when it did it was ok'ish so i drove it down,
luke at the garage said he did the timing perfect and it wouldnt be that anyway, he thinks it could well be the hall sender but hes guna test everything today anyway, get it running smooth and then sort the starting issue.

Did he set the timing with the blue temp sender unplugged? If not, then your timing will be out. Might not be the route cause of the situation, but it really won't be helping. Only reason I'm suggesting this is because you mentioned that it got worse after he'd done the timing for you...

Did you stick a meter on the battery and check that it was healthy prior to starting? And what is the voltage with the engine running?

Hall sender failure normally means intermittent bad running, or complete failure to run at all.

timing was all done correctly,
just rung garage, new bosch dizzy on the way, they tested everything, all fine, everythings been replaced except the dizzy ie hall sender, so the problem is pretty obvious, £140 in total for the dizzy and the work theve done. il let you all know when i get the car back and let you know the differences, thanks for all the help.

When a hall sender fails like andy said usually it completely dies and you cant start your car but it can be an intermittent problem some times car runs does not fail for a couple of days then it will die again and keep failing every 30mins then it would work again for example. the hall sender don't normally course the problem you are describing.

when and how did the problem start was it when driving or has it been parked up? was after you changed any thing? is it a problem that started off minor and has got worse?

also could it be your fuel pump? try removing your fuel rail with injectors and crank over the engine check fuel is being sprayed from all the injectors?

my car is a daily, it gets used almost everyday,
it all started, i remember the exact time, i was tightening the boot popper. i removed it before hand, and the tube that connected to the central locking, i forgot to connect the tube back to the pump, so when i locked it the pump kept whining for ever, so i connected the pipe back on and went to go out, and the car wouldnt start, i thought the pump doing that had worn the battery but since then its got worse and has nothing to do with the battery.

since then my car has wanted to start just wouldnt fire up, it started normally like 3rd go, it had its days where it would start first time or 10th time.
i then had new oil, plugs and remap chip done, after that it started 1st time... for a day :( then back to normal, then it got worse taking 10 attempts everytime, but like i say it had the rare occasion where it would start straight away?
when it ran it felt the tiniest bit shitter to drive, but by this time i was used to it so was probably alot worse than i thought,

when i put the new parts on it still didnt start, and when it did, it was terrible, the smell of petrol was crazy! and the car literally shook violently like it was running on 1 cylinder, after a few seconds it just died, as soon as i put the old leads back on it was fine (still didnt start, but ran)
the new leads were g40 specific from euro parts, fitted how they should, even a mechanic (my mate) checked them,
so im thinking dud leads maybe? but leads or no leads that still didnt solve the starting up issue.

hopefully with the new dizzy my problems will be solved and i can start liking my car again, coz atm i hate the thing!

sounds like a fuel problem not a spark problem maybe!

things to check remove fuel feed to injectors turn ignition on check fuel is pumping out or like i said all ready remove injectors with fuel rail crank engine over check fuel is coming out of injectors? easy things to check then you know if it could be the problem or not help pinpoint the problem you could keep replacing parts all day and not solve the problem.

also remove king lead HT lead from dizzy cap keep the other end in the coil and check it receiving spark by earthing it. then try removing each HT lead spark plug end stick a old spark plug in the end and check its creating a spark at each ht lead? if its getting good sparks its all fine and the hall sender is working also!

mate at garage said one hundred percent nothing to do with fuel,

anyway...  PROBLEM SOLVED!

the g smiles are back!
after new:
coil, leads, plugs, dizzy cap, rotor arm, whole dizzy lol the car was running so so much better, the starting issue was much better but was still not up to standard,
it turned out to be something to do with the ignition bit near the key?? im not to sure, it cost £30 from vw, and 2 new relays and its now better than ever!
i was told by my mates at the garage that the hall sender was fooked along with the coil so that was the reason the running was crap and like i said the £30 part from vw is the reason it wouldnt fire up.
so relieved, i took it on a nice little hoon and its soooo much smoother and no more lumpy-ness :)

hope this helps people with the same problem as me, dont buy everything because it could just be something simple, oh and if ordering from euro parts they send you different brands to what you ordered lol i got a beru instead of the brand i ordered, but wasnt complaining lol
