changed the coil to an aftermarket one and now it wont start

[tim_blair]

i changed my coil to an aftermarket one and it didnt work so i changed it back to the factory one but now it doesnt work

it turns over but no spark
its a BT 4age with link storm ECU

i looked at all the fuses i could find but they are all ok is there any less obvious fuses that i should check?

what could be the cause?

does anyone know where there is a wiring schematic that i can look at?

[Grrrrrrr!]

What sort of coil did you put onto it? WAS it a MSD (or other CDI type) coil?

this is the one i used

[Grrrrrrr!]

just noticed you are using a link....what igniters are you using?

[tim_blair]

factory

[QikStarlie]

looks like a cdi coil. probably cooked your ignitor. hope it hasnt damaged the link.


did we not advise you against doing this in another thread?

[tim_blair]

yes you did advise me against doing this with a different coil so i chose one that was "aparently" more compatable but obviously it wasnt

[QikStarlie]

ah yeh. first thing i'd try is another ignitor with the stock coil.

will most likely be the problem

[tim_blair]

are they common amongst toyotas? or will i need to get a BT specific one?

[QikStarlie]

others will work. some have different plugs though. on the link it will only be using 3 of the teminals/wires
ive used quite a few toyota ones on links, but cant help with what will interchange with a blacktop one though sorry

another thing.. did you ground the igintor case when you changed the coil? as they ground through the case

[tim_blair]

not at first as the instructions didnt say to do so, then when it didnt work i earthed it, but still no luck

[tim_blair]

actually no sorry i thort you said coil case but i moved the igniter so the coil wires would reach and never earthed it so maybe that is the problem ill go have a look

[tim_blair]

YOU MOTHER F@CKING LEGEND IT WORKED!!!!!!!!!!!

so you just saved my car whats your account number?

[QikStarlie]

haha all good. Don't worry earthing the igntor case has tricked many many people!

[tim_blair]

man i cant believe that! who would have guessed that with all those wires coming out of it is still earths through the case,

so do you think i should try hooking up my new coil now?

[allencr]

so do you think i should try hooking up my new coil now?

Go for it & please write about the sparks appearance length & difference from the old one.

[QikStarlie]

yeh nar

"Ultra Low 0.32 primary resistance"

cdi coil is no good for your setup. there is no need to upgrade the factory coil unless you have a misfire. which you wont on a na setup. nothing to gain, not broken, dont fix it

[tim_blair]

if i did it what could it possibly damage?

[QikStarlie]

ignitor and possibly the coil.

you need a coil that works with inductive system, if youre set on changing the coil

[tim_blair]

what is the reason you think that it will damage my ignitor/ coil?
is it bacause of the low primary resistance?
if so could i put a resistor in series before the coil to reduce the current draw?

can you please explain what you mean by a coil that will work with an inductive system?
