My '97 model XH falcon I6 refuses to start. It has plently of spark at the coil lead, has new dizzy cap, new rotor button and new leads, yet I get zero spark at the ignition leads (no matter which one I try). The rotor button is definately turning and I've done a ECU test which said no prob...

Thoughts are TFI?? or computer??

Help please!

I would be checking those leads again for a start, then maybe pull the dizzy apart and check if thats all good and then I would check battery voltage to make sure its over 11 volts.

Battery is showing 12.7v and I've tried two sets of fairly new leads (I highly doubt every lead in both sets is stuffed).

Hmm. Computer must be getting power if the test reveals no codes ( I presume the light did flash somewhere, with the computer ID if nothing else...).
I would suggest the TFI as well, use the voltmeter to check your power inputs to the TFI.
Although if the coil is generating spark, the dizzy must be breaking circuit so as to collapse the field in the coil. Interesting problem there man!

Righto, I'm now getting a spark but its pissweak. Going to check all the grounds etc in the morning and see if that helps any.

Thanks for the help thus far.

Found the problem, the coil. After taking it out it appears to have a few small cracks in the housing.

Thanks to all for their help and suggestions. :s4
