1997 Honda Civic CAR CUTS OFF

First off, the car would start but would just cut off. I notice a battery light, and saw it was the wrong battery in the car. So, I replaced the alternator and the battery. Car started right up, but then cut off again. Then I checked the main relay, it was bad, so I replaced it too. Car atarted up again but cut off again. I've check all the fuses everything checked out ok. Now the car doesn't start, just turns over, no sparks, I've rebuilt the distributor and still no sparks, but I've had tested the distributor in another car, work just fine. I also checked the computer it was fine, I mean I check timing, tried a new crank angle sensor, did a compression test 130 across, still no spark, now I think its the ignition switch. So any advice would help, thanks
