running probs help!!

[Dave Reed]

TBH if its coughing & spluttering the afr's will go all over the place.

So you need to start eliminating things that could cause poor or no spark.

Check for rotor arm condition

Check no moisture is in the dissy cap (is the o ring in good nick)

Remove the sprak plugs and check the colour

make sure all the leads are plugged on nice and tight to the spark plugs (if not squeeze them a little with pliers) You can also take a resistance reading to ensure they are within tolerance, very easy to do with a multi meter http://www.youtube.com/watch?v=DI_aI8KElrM

Make sure your spark plug gaps are correct
Check the voltage at the AEI

Check your tappet clearences

Check that there are no exhaust leaks before & after the lambda sensor & where it screws in.

Check you have no air leaks on the inlet manifold/carb (buy a can of easy start and have a spray around, carb base, carb,inlet manifold).

Missfire on boost will show as a lean spikes on wideband

[KEV 5 GT]

well ive put another aei on new plugs / leads new dizzy and rotor arm / rebuilt carb with all stock jets....i can pick a spanner up but when it comes to electrics im not that good

You still have some more things to check on the list. Tbh its near impossible to guess the fault, you need to fault find. If you can't do that, then I would suggest taking it to a specialist.

What is it you dont understand about 'electrics'? All you need to do is take a voltage reading or a ohm reading, I even posted a video to show you how

[KEV 5 GT]

that vid only shows you how to test the plug leads does it not ?
and there new ? ive just changed the acc jet and thats done nothing...

Just because something is new dosent always mean its good. Have a look on youtube how to use a multi meter, its very easy.

Have you checked the rest of the stuff on the list? Honestly fella you need to check everything, post the results up and we may be able to help further.

I personally think you have an air leak or a blocked jet in the carb Or a bad earth causing you issues, but it may be none of them. Just trying to help you out

[KEV 5 GT]

where do i need to check for air leaks dave ? would that acc jet cause the prob
im gonna get another tdc lead 2mo as the one thats on is a cheap copy and im sure its a phase 1 tdc if that matters at all but i know the plugs dont click in right

[Dave Reed]

You need to buy a can of easy start and get spraying it around the area I said in my previous post. If revs up or the engine note changes when you spray it in those areas you have an air leak.

Tdc sensor could well be the issue, especially if it's not clicking together properly..

[KEV 5 GT]

thanks for you help and patiance dave and all others i will put a new tdc sensor on and do other checks see whats what and let you know

[KEV 5 GT]

well just chucked a new tdc lead on there seems to be a better spark now but she struggling to fire now and wont start theres live to the aei as well but sommots holding her back it seems like ive checked everything over and over but still no good

[KEV 5 GT]

right checked all plugs / leads dizzy cap ok checked every thing said put another acc pump jet in that works ok now seems alot better the misfire splutter is still there but not quite as bad ??????

[Fordy]

pump jet shouldn't be affecting it starting or running on idle only when throttle pressed will it inject more fuel as the butterfly opens.

Hard to diagnose over forum chap, I bet someone local with knowledge on these would be able to get it running properly in a hour or 2.

[KEV 5 GT]

does anyone local wanna help me out here ??

[Dave Reed]

Where are you?


just looked on your profile - Leicester

[Dave Reed]

Have you check for air leaks yet?

Also try adding an extra engine earth, you can buy them on ebay cheap enough Or get one from ya local motor factors.

[KEV 5 GT]

there dont seem to be any air leaks not that i can see of dave and i think theres been an extra earth wire put to the engine ive got some good thick cable is there another earth wire i can put on then ? if so wheres best to put it ?

[Dave Reed]

You won't see an air leak, you need to test for it with easy start.

You can put extra earths on any bolt on the engine. I had one near the water pump and gearbox (the cover plate for 5th gear).

[KEV 5 GT]

tryed the easy start and dont seem like theres any leaks
theres an earth from the battery to the bulk head someone has put there
i got a thick cable and touched the battery and put other end to the rocker cover bolt
but dint seem to do anything ?

Good stuff

the Rocker cover has arubber gasket so not the best place.

Go from the earth on the bulkhead to the back of the inlet mani stud. Or for temp measures go batt the any bolt on the g/b or engine, just not the rocker cover.

Noticed the gearbox one the other day when I changed the loom.

[Dave Reed]

Have you tried cleaning the idle jet too?

Little test you can do to see if you have a blockage is undo the screw slightly (so the rubber is just of it's seat) and try start it.

[Dave Reed]

I hope you kept it

[KEV 5 GT]

its gotta be sommot stupid cos once its running apart from flat spot at around 2k and the splutter between 3/4k she flys....

[JamesF]

I hope you kept it

Yep. It'll be going back on. Also, you know that bar going across the inside of the roof (that took me hours to remove ha) that was what was making the roof sag near the sunroof, if was pulling it down. It's fine now.

The whole roof sagged when I removed the roof lining, that's why I put the bar in lol.

Get a project thread going.

Weird. When I cut through either end of the bar there was a 3mm gap either end. Battery seems to be on other side too. Also assume you had a rev limiter on left side. Mine screws straight into existing holes ha.

Sorry for going off topic.

[TopCat]

Hesitation generally means leaning off, have u got a spare fuel pressure regulator? Maybe give that a go.

[KEV 5 GT]

ive not got a spare fpr but i noticed when i took the dizzy cap off it looked like the rotor arm was only just catching the prongs its a 21 turbo cap due to front mount i did pull the rotor arm up abit the other day but had it off again and the marks on it was still just catching it was working ok but maybe thats at fault here ???

does anyone know if the 5 gt rotor arm sits higher than the 21 turbo ?

[Brigsy]

You need to use the standard gtt rotor arm with the 21 angled cap.

[KEV 5 GT]

hmmm we maybe getting somewhere now then ive just put the 21 turbo cap and arm on and like i said only just looks like its catching im hoping this will put and end to my issues....

[Dave Reed]

Lol you could of told us that days ago

[KEV 5 GT]

i only looked for the 2nd time today dave lol after i had pulled rotor arm up
so only seen today mate lol god i hope its just this after about £150 spent
fingers crossed this is the prob

[jermaine666]

Did u manage to sort it kev

[KEV 5 GT]

ive not had chance to swap rotor arm yet mate i will try and sort it weekend and let you all know thanks for asking

[KEV 5 GT]

well not good news i changed rotor arm today and she still took ages to get going and the splutter is still there so still no good..... when she did go i noticed abit of warter coming out the top gap where the turbo bolts onto manifold but went away after few seconds when warm....im not sure what else it could be bout ready to give up

[jermaine666]

I had the same problem for the last 2weeks and it was my tdc.

[KEV 5 GT]

what was wrong with the tdc ive changed mine 3 times now

[jermaine666]

It was the top part of my tdc wire I changed the bottom part twice and it didn't do a thing.
so I got a ph1 tdc and that solved my problem.
Have u change the top part of yours or just the bottom?

[KEV 5 GT]

ive not tryed the top part you mean going to the aei ? only the part going to gearbox
i did think about the top half if thats what you mean ? so was this you prob sorted and if so where did you get the top wireing bit from ?

was your car hard to start ?

[jermaine666]

Yes the part that goes to the aei, i got a ph1 tdc and that goes from the gearbox and plug's into the aei
so its just one piece.
It was a new one £15 from cgb.
this fixed my problem.

[jermaine666]

It was not hard to start but the afr's on idle were all over the place.

[KEV 5 GT]

im having starting probs as well takes ages to get it going for some reason once going it seems to tick over ok but take it for a run and get hesitation bit of cut out at 2k ish then 3k to 4k proper splutter the boost kicks in and shes away im stumped

[jermaine666]

That's what mine was doing. I could not even boost it as it would missfire.
If ur after a ph1 tdc the eBay number is 160572676967 there is also a used Ph2 top half tdc on there

[KEV 5 GT]

ive tryed a ph1 tdc now gone back to ph2 tdc as they click together proper whats the ph2 top half on ebay mate ?

[jermaine666]

Yeh its on eBay.
Did you connect to the ph1 tdc to the aei the or to the extension?

[KEV 5 GT]

ph1 tdc to ph2 top part to aei

[jermaine666]

You should of put it straight to the aei.
If u have still got the ph1 tdc give it a try

[KEV 5 GT]

no noy got it now

[jermaine666]

161233927903 thats the eBay number for the ph2 top tdc
