I have a 93 gs special edition(b18a1) that wont start. It cranks over but no spark. The alternator and battery/terminals are still good. Getting fuel as well. The car cranked about 2-3 months ago and ran fine then sat up. Nothing was touched or tampered with during this time. No air restriction either and no wires, tubes, plugs, and connections are loose from anything I've seen right under the hood. I never got to much time to really mess and play with it. Most people seem to think its a in car security mechanism keeping the plugs from firing. A bit of research led to the same sort of issue, talking about a ROM sensor needing to be replaced. Anywho, sorry if this Q has been posted before. I searched through only about....400 topics before deciding to just post one. If anyone knows a site or previous post on this matter, feel free to yell at the noob for ignorant posting. Just make sure to link me up or help me out while you do. thanks-

P.S
I did just buy the car awhile back and there was some aftermarket stereo/alarm crap that had been removed all before I purchased it.

 

did you make sure that the spark plug were not bad. maybe try checking some of the fuses to make sure that they have not blown.
