No Spark - No Start Condition 91 240sx

[irocknrol2]

91 ka24de m/t 240 just suddenly decided it doesnt want to start. Over the last few days I have read a lot of topics in search and followed as best I could procedures in the FSM. It is not showing any codes. I have power to the crank position sensor, the coil, the power transistor, but I dont have any spark at all coming from the coil to the distributor. But yet when I measured the resistance on the coil it checked out with .7 as indicated in the FSM. I checked the resistance in the coil to dist. wire also. I am stumped. I hate to get into the change a part to see if it works mode. But it seems as if it is a bad coil.

Any thoughts? Also the advance auto store carries 2 coils, 1 from Hitachi, and 1 from Mitsibushi, the hitachi is much cheaper for some reason, does anyone know if they are car specific? I wouldnt think so, but you never know. Mine has a mitsibushi on it now.

if u plan on finding a coil/powertransistor for cheap just check the forums. i just swapped a ka back into my sr20 pwrd sileighty to pass emmissions but im not getting spark, i just picked up an extra coil for cheap and im just gunna swap them when i get home. if that doesnt work im goin back to checking wiring again and agian

Update::Although I didnt really get any replies I wanted to post the solution in case some one searches and comes across this thread. It was loose grounds.
