Cluster caused problems!Need help FAST!

I picked up a guage cluster off a 90 DX that had a tach in it. When i ripped everything apart and plugged the "tach" cluster in, the car it wouldnt start! So i removed the new cluster and threw the old cluster back in, and would still not start. I looked over every fuse on the car and it was all ok. The car just sits there trying to turn over, but there are no sparks coming off the sparkplugs. I dont know if I blew the computer in it or what but im freakin out. I need help badly cause i have tried everythin i can think of!:eek: :confused: :(

I doubt it is a related probablem, probably an odd coincidence.

Check your Distributor as that is where the spark is generated from...
