 Ignition Problems 18r-g

 My car has no spark and I was after some advice on where I should look. It has been driving pretty normally apart from about 4 cut outs in the past month were it started strait away. But this time it cut out it would not start. After now checking a spark plug and confirming no spark where should I look. It has an after market cran cams fire ball XR700 ignition booster set up(maybe it broke)or could it just be the coil, or something else. How can I check my coil? HELP.

if you have a multimeter try a continuity test across the ballast resistor.
it is a little white ceramic stick near the coil if you dont know what it is

No ballast resister, it is a positive ground hook up set up with a optical trigger set up in the disy.

ok so you obviously know what your talking about im a bit of an ameture at this sort of stuff but how bout measuring the voltage drop over the coil. also have you tried new plugs as it could be possible that they have become fouled. also check the resistance of your leads.

hey if its a positive ground wouldnt you have to change every single little electronic bit on your car as most jap cars are a negative ground? or am i missing something?

Just keep working back. No spark at the plug? Check for spark at the coil. If not, check the ignition moduel has power and earth. If it has, check the hall effect thing is working, as they can fail. The hall effect sensor is suplyed with power in one wire out of the 3 that go to it, but very low current. If you have got spark at the coil check the plug leads.
