my 3rd gen rx7 keeps flooding and its only the rear housing, i did notice the T2 and L2 spark plugs were not firing, i inspected the car and found that the igniter had a loose ground, after i grounded it how its suppose to be the sparkplugs ignited and FD ran great for 3 weeks, then the other day it flooded on me again! and now no spark again. the ignitor ground is in tact i cannot find the problem, does anyone know wats going on?? oh and they do show one spark when i turn the car on but when i crank the engine no spark!!! please help!

You said your ignitor had a bad ground...and it's now "in tact". I'm not certain, but thought it was grounded through the mounting bolts. Is that where you cleaned?

yes.. i found it just dangling and i guess it would flood on me because when i drove the wire moved and it would sometimes flood then unflood itself while im driving... because this wire would touch the metal (car) and sometimes not touch it according to wind or how hard i rocked the car. when i found it i immedietly put it where it should go which is on the mounting bolt on the upper corner of the ignitor. i also cleaned that area as best as i could. after i did that the plugs fired and car ran flawless for 3 weeks, now its back doing the same thing, no spark thus no combustion.. all my other grounds look fine aswel.. just cant explain why it would be fine for the limited time then the same thing again..
