The power steering pressure switch is located on the driver's side, rear of the engine bay near where the rack goes through the firewall. It could be unplugged or not clean. I don't think it would keep the car from running or having spark but I'd have to double check that.
Do you have the bottom two bolts that connect the DIS on the crossover tube? If not then you need to make sure they're on there. Make sure that the DIS and the contact area are free of any dirt or grime.
Have you checked your coil pack?
Typically when a car is running prior to doing some work and not afterward it's something near where you did the work. Recheck everything you may have unplugged or even bumped when you last worked on the car.
