car wont fire up...help!
 

ok car was running...sourced a set of used coilpacks
as 2x of mine were cracked.

changed them over and car wont fire up... checked plugs and im getting fuel...

so I put old ones back and still wont fire up... so what the hell have I done...???

I'm sure you haven't but you did put the right leads on the right plugs didn't you?

Shane

Is there a spark at the plug ?

iv not checked for a spark....as the old ones were working...I cant get my head around what would change....the leads have a black plug for the coilpack toward front of car and a white plug towards back of car perside its spun me out...cars stuck at work..and I cant think what would do this...

Black is normally back

hmmm....ill try swapping them...would car run on 2 if I just swapped 1 side??

Yes but I'd do all 4

ill do all 4 if it starts to run...at the mo it wont run atall

leads wrong way.....tit :/

At least it is only your pride that needs repairing though. :D

yep....lol just took it for a long run and its still missing underload slightly worst than before I changed packs...

the old packs had cracks and signs of melting.. theses ones are fine.. I put new plugs as recommended here.. platinum 7 grade..

cars running pants... any further ideas peeps??

I retract that comment then lol, glad you've sorted that problem even if the original problem hasn't been fixed.

I'd try a new set of leads to see if that helps

No leads on this year wrx,
Things to think,
Maff,
Boost leak,
Fuel cut,
Induction kit clean,

you have soaked the plugs in petrol so wont be helping .
all ways remember" black is back "

I replaced maf November
100% nothing like fuel cut...
Induction is clean.

thing is I was getting a flat spot that started to get worst under boost around 3500rpm 4000rpm
Changed plugs and noticed 2x coilpacks had cracks and signs of melting...so clearly that was my problem
now on coilpacks with no cracks plus I taped them under rubber boot..and the car is worst...missing on and off you can feel the spark come and go almost...
also smell of fuel??

take tap off , there is no need for it

iv been reading on scabbynet....and this seems to be kinda common but with no real answer...
im going to check gaps on plugs and clean maf anyway...

is there a way with a metre I could check each pack??

Aren't the MAFs on classics quite fragile? Cleaning it can goose it I thought.

on the drive home (10mins) the car ran ok...till just before my house then a little miss... so its when it gets hot it starts to run lumpy(misfire)...does this shed some light??

Coil packs how tight did you do them up you can over tight them, mate don't give up after owing now evo and all sorts of scoobs I still think the early classic is awesome and because of it's price and rawness

have a coil pack tester.. voltage and arc... found passenger side front port was my problem...checked coil pack and broken up and messed plug up to...so changed plug and used 1 of the old coilpacks that wasn't cracked...car ran fine tested voltage and arc and was same as the others...raised rpm rechecked all was good... drove home car ran perfect till just before my house lol!!! iv got to laugh or ill go metal!!!....started missing again... so I know its that coilpack... I just don't have another to swap... there so expensive new... total pain in the ****!!:(

Convert some newage paks?

This should only be a temporary fix to help packs with cracks.
It's quite common for the pre-facelift to suffer spark issues after changing plug's because the weakened packs get damaged further when re-fitted. And many don't know that there are cracks under the rubber boots.

Coilpacks were one of the reasons I stopped doing the chips. People were quite happy to pay £150-£200 for a chip/ECU upgrade, but were not too happy when they also found they had to pay £250 for a set of coilpacks.
I only ever had 1 guy send the chip back for a refund, I reckon because he couldn't afford to sort the coilpacks.
As the cars got older this became more and more a problem.

I must have hundreds of emails trying to convince people it was their coilpacks and not the chip causing the problems. When they eventually swapped to new coilpacks they were eating humble pie.........the big problem was that before the chip they ran fine, but the extra boost provided by the chip would blow the weak spark out.

i did the newage conversion on one of my old wrx's easy to do.

thing is when it comes to wiring im pants...spanners nuts and bolts quite happy... I wouldn't be convident to do this conversion...

does anyone want to earn a drink lol....

I can see how this would happen...I bet it was a drama...the coilpack fault almost comes across as a boost problem at first...flat spot ect....

What have you gaped plugs to ?

they were 7 out if boxes...I went 6.5

Cool :)

0.65 I hope you mean't

yep yep
:ok:

you can even go to leads also there was a link floating around showing this how to.

I read this last night...made a lot more sense so im going to do it...so I now need a set of newage with looms...have you any???

There's a scooby breakers on eBay selling sets of newage coil packs for £50 delivered I brought a set last week don't think they would want much more with a loom I can send u the link if intersted ?

please mate...:)

http://m.ebay.co.uk/itm/181324892685...id=31612348603


There's a contact number on the listing give them a bell mate doubt a set with the loom will be more than £70

I've got all this fun to come as one of my coilpacks is weak/not working :/

well iv got a tool to test which one it is if you cant see any cracks....:)

That would be really handy to use!

I bought 1 new coilpack and replaced that plug also... retested perfect...run car afew days now and been fine till last night!! bad miss fire on boost only...same port... am I missing something???

ok..bought another brand new coilpack just incase the 1st one was dodgy...soon as the car gets up to temp missfires...it popped flames lighting up the rear view mirror!! and again the same port...passenger side front...

new plugs
new coils

what else could it be?? its that 1 port that goes down when hot..

I've got a set of newage packs if your still after a set

just checked codes as i reset ecu yesturday... iv got code 42... does this shed some light??
