Look for power transistor.. you check continuity between pins..

Page EF&EC 125 in the fsm..

Also check continuity when the unit is hot, put it in the oven at about 40-50 celcius and perform same continuity test..

Turn the key to the run position, grab the business end of a coil, and spin the CAS. If it hurts like a mofo, igniter works.

oh one more quick question, does the lead that comes of the fuse box ground to chasis or go to the positive lead on the battery?

Cuz i swear i was working on a car a couple months ago and it lead to the positive side, currently i just have it on the chasis cuz i figured at least if im wrong about it its not gonna go blowing fuses or anything.

Pics? Is it black with an eyelet on the end? If so, it grounds to the chassis.

Check cam timing. Set the motor at TDC via the crank pulley (2nd mark from the left), pull the upper timing cover, and make sure the dots on the cam gears line up with the marks on the back cover.

Take pics cuz ppl often look at the marks on the cam gears wrong and think they're lined up and they're not.

Check your injector resistor pack. They're known to fail. It could also be a wiring issue.

I like the wiring issue being at fault. Ignition modules usually don't fail as a whole, so his engine should crank if it was wired correctly. Injector resistor packs is last on my list and I say ths because most don't even know what it is let alone have one attched to their harness. Look over the work real good and do it again until you find your issue(s).
