its bulls*it i have blown 3 coils in 3 weeks the first time it just stoped in the middle of port rd had that fixed then it blew agen and i towed it home and fixed it myself found some water leaking on to it thought that was why it had blown but a week later and no water leaks its gone agen adleast it was still in the drive way no towing this time

i thought it could be dodgy earths i thave started taking them off and sanding the terminals i dont want to spend anouther $60 on it so it can leave me on the side of the road some were any ideas would be great

its a XH 97 5 speed factory LPG resent work has been central locking new stepper motor (LPG s**t) and new oxy sensor dont recon any of those would do it tho

cheers

it could be the tfi module on the dizzy on its way out?
i have heard the sometimes when the tfi is crook it can cause the coil to fail?
it might pay to get a new tfi module aswell..

sounds like you have a big issue there.. does your motor get hot/overheat? it seems that the coils with metal brackets break when the motor gets hot as the brackets expand and crack the plastic casing. try only putting 1 bolt in and make sure that lil resistor thing is plugged in

I had a similiar problem a while ago, the car just stopped on the highway, got towed home, fitted a new coil, it shat itself a week later. This time i replaced the coil and the TFI module, been going like a train ever since. The TFI can feed back into the coil and f**k it up. Replace the TFI with a new one, and all will be well.

The TFI module can't break the Coil. All the TFI module does is provide the (PIP) signal for the negative trigger pulse for the coil to fire. It's not as if it's go pump huge amps into it and fry it.

Heat stuffs coils and TFI modules. A faulty Hall effect pickup sensor underneath the chopper disk in the dizzy can cause the TFI module to fail also.

Just relocate the coil somewhere where you can access it easily and keep a spare in the glovebox or boot.

My coil would now take approx 2min to replace if it every fails again since I have relocated it.

Cheers..

Are you sure the coils are breaking? I bought 2 second hand coils for my EA a while ago then just went and bought a new coil thinking they were all broken, turns out it was only the high tension lead between the coil and the dizzy... something worth checking?
My EA was just randomly stoping then wouldnt go until I put the new coil in, which was probably bending the lead and re-conecting it for a while...

i put new leads on it at some point cant remember when but i have only had the car 2 or 2 1/2 years so not that long, how long are they ment to last? i will run continuity test over it any way
