no fire??????
ok my friend has a 88 gxl 5 speed the poles were switched around and it has a kill switch when its on it kills the car. i used a dc tester.and it was showing some power. but when we pull the spark plugs out and set it next to a bolt or a ground to see if it would shoot a spark,nothing happens. whats the possibility of the coil packs going bad?? what all could cause the coil packs not to fire? we changed out ecus, and we checked all the fuses. the main was blown. so that omeone had to really screw something up. we tried to bypass the fuse by hooking them together to see if that would help. people gimme some ideas. thanks

Go to this thread https://www.rx7club.com/forum/showth...hreadid=138766 and I posted some ideas there along with some jpgs.
While here though////// check and see if there is 12v at the black/yellow wire on the small white plug for the lead coil assy. No voltage, no worky. Use a cheap or expensive digital volt meter so you don't fry some transistor in the ECU. Then read the https://www.rx7club.com/forum/showth...hreadid=138766

You really need to pull the MAIN RELAYs plugs off and see if you have 12v on the black/green wire and the white/blue wire.
The black/green goes directly to the fuse box in the engine bay. Its a 40 amp fuse. Should be a straiht shot from there to the main relay. No 12v at the black/green, no worky. It has to be a fuse or a broken black/green wire.
You might pull the 40amp fuse and see if there is 12v on one side of the prong the fuse goes into. If that there, then put the meter on ohms and put one lead on the other prong of the fuse and the other lead on the black/green wire at the main relay and see if it ohms out. Should be like .1 or .2 ohms.
You just have a fuse problem or wire problem. Not a big deal. Don't crank the engine anymore till you have 12v at the black/green and white/blue wires. Piece of cake.
