No Spark, Coil Power
 
Hey everyone! I'm the new kid on the block. I have had my 87 RX7 down for three weeks now! I need help. I never had my 1st gen (81) down this long! You seem to be the most knowledgeable group on the net and I need help.
I am a woosy that paid a mechanic to replace my clutch because I have no heat in my garage. Since then...
I have no spark. There is power to the coils, and no spark on any plug. Resistance checks fine with the three coils and ingitors are ground. Test light says no power at the end of each wire. Plugs and wires are new. NGK plugs and solid core autolite wires. New starter/solenoid, crank angle sensor fine, main relay ok, battery good, ignition switch good. What the frigg is stopping the spark? I'm mostly a parts replacer not a mechanic. ie on the 81 I plugged the vacumm hose for the dash pot valve with a spark plug for two years because it took forever to figure out it was a dashpot valve. Anyway, is there a way to test the ignitors or a relay I'm missing somewhere? Any ideas would help. I hate driving my 84 firebird with t tops that leak when the snow melts.

This happened to my old T2, when the AFM goes kaput, the computer will not allow spark. once me and the new owner picked up a new (old) one from a junk (or 'salvage' to be p.c. about it) yard and threw it in there, she fired right up. Find somebody locally who might let you try throwing theirs in your car as a test. Worth a shot. Good Luck!
