I'm having a no spark problem that came on suddenly after changing my spark plugs and wires. As soon as I finished changing the plugs and wires, it started up and sounded perfect. As soon as the engine got warm, (5 minutes of running) it died like someone turned off the key. No sputter or anything. It would crank but no spark after that. The weird thing is, after 24 hours of sitting with the negative battery terminal unhooked, I hooked up the battery and it started back up and sounded perfect again. 5 minutes later it died. Once again, I unhooked the battery, waited overnight and it started again and died again. Now it won't start at all.
I've replaced the coil pack, the camshaft position sensor, the ignition switch, and the crankshaft position sensor. I've tested every fuse and tested every other sensor I can think of that could cause the computer to not tell the coil to fire.
The only thing I can think of is that one of the new spark plug wires somehow fried the computer.
Tomorrow, I'm going to the junk yard and getting a PCM and trying that. I'll let you know if that works.
