Urgent help. coils swap - car wont start

[r0ma]

Hey guys, ive had problems with my coils on my R33 GTS-T . ive just got some from a low km engine and put them in. now the car wont start.

what have i done wrong?

is there a specific order or any thing?

[blind_elk]

is yours a S1? Are the replacements from a S2? Because the S2 had the ignitors inside the coils, and they won't work if you already have an ignitor pack for your old coils.

[r0ma]

nah there from S1..

[Morgs]

Ignitor connected properly including the earth?

[The Dan]

yes they have to be in specific order if you leave them on the bracket. but as long as the plugs all match up to corresponding coils then I can't see a problem. Check what Morgs said. Earth is often the problem. Plus check the basics as it may be a coincedence but it might not be anything to do with your coils. might sound funny but it have seen it before. Check to make sure you are getting fuel and spark. Have you got a HEI (High Energy Ignition) tester? if so.....use this to test your spark. If not...go and buy one...they only cost five or ten dollars and it'll show you if you're getting the required spark from the coils.

hey guys.. f**k knows what the go is..

ive put the old (no good coils) back in, and it fires strait up..

try with the new coils. and nothing.

its got me stumped. so the cars still running like shit. and ive got these coils ive just purchased that appear to be no good to me.

they came from a S1, but are defently differant.

[blind_elk]

i think they have to be from a S2

[r0ma]

nah they were working fine in another S1, taken out to be upgraded.

[strutto]

Could be from a S1.5... S1 Body with S2 motor...

[r0ma]

is any one able to confirm the numbers printed on them.

the original stuffed ones had 5**

the new ones had 3**

printed on them

My S1.5 (S2 engine) has '533' coils and I have a S2 coil (from a S2 car/engine) that had '6xx'.

Sounds like you have the wrong coils (ie your mates car was a S1.5 with a S2 engine and your car is a S1).

[Zahos]

pull off a rubber boot from one of your coils, and one of the purchased coils.

I purchased some that were missing the little spring that sits inside the boot, and the ones I bought had corroded / stained metal.

I cleaned them up with bi-carb soda and steel wool, then put the spring in (dunno if the spring makes a difference) and they worked a lot better.

But from the sounds of it, sounds like u got the wrong coils
