Not that I'm offended in any way (you wanna hear the mouth I've got on me) but there's no way it can just slip out when you're typing it.

ok well im alittle frustrated. i love the car handles and runs great. when it does run but it keeps llosing power to the first 2 coil packs and leaving the third one(or first one off the harness) with spark. so maybe its in the splice were the other 2 keep loosing power or bad connection

A bad ground can cause crap performance but it won't kill a coil.

thanks for the link i was just about to go look for one. Im thinking it shorted out. the 3 hot wires coming from the harness going into the coil pack were exposed completly at the splice. so i re heat shrinked it. but all my coil packs are dead. i got power going to them but nothing coming out. -_-. anyone have a coil pack for sale?

thanks for link, im assuming i fixed the problem. does it make sense that my coils could have shorted out due to the exposed power wires -_- should have noticed that when reinstalling the new coil pack.

You're more likely to destroy the igniter or ECU from shorts in that area then the coils.

Which wires were shorted? Post colors and pin numbers: http://www.cygnusx1.net/Supra/Librar...x?S=Main&P=040

You really need to dig in and clean up that harness if you've got that many exposed wires... it's possible there's a lot more damage than just that unless you know that area's screwed up just from someone dicking with it in the past.

Measure the resistance across all of the coils and compare, that'll help you identify which ones really are suspect... if any. The process is covered in the link I gave you, did you bother to do it? http://www.cygnusx1.net/Supra/Librar...aspx?S=IG&P=12
