This is what a mechanic gonna test by....http://www.lunghd.com/Downloads_and_...ion_manual.pdf

I am gonna try and replace all the fuses on the side.
Can off timing cause NO spark at all? Just wondering...
(Never dealt with off timing)
*Edit* On my Chevys I could have off timing but still get spark.
