Default 1990 civic back from the dead?

Im trying to bring this 1990 Civic back from the dead, it hasnt ran since 2003. Okay. I replaced timing belt, water pump, battery, then change oil, fresh gas, filled radiator ect... So starter wouldnt turn when using key. But would turn if jumpered strait to battery. Fuse was fine. Wasnt getting any gas. So I poured a little in throttle body then jumpered battery to starter and walla, sounded great till fuel ran out, then we tried again and it started good again, then I hear a small "pop" car died. Checked fuse block and stater signal fuse was blown. Replaced fuse and try again, now no spark. Where did spark go? I am getting new fuel pump for it in morning, but could no fuel pressure be affecting the spark at the distributor.

may be you must have not placed the fuse properly, check the fuse again, it might be unplugged.

I checked the fuse again. It was still good, but i replaced it anyways and still it didnt work. I getting a new main relay in morning, just a shot that this could be the problem. I saw in repair manual that this one relay 1st signals the fuel pump. 2nd signals the starter, then 3ird signal to the ECU. I ran 12 volts backwards from the starter signal wire to the fuse box to check the wire it was good. Then I found the ingnition wire in the steering collum and jumpered starter signal around fuse to ckeck if working, it was good. So im thinking very HOPEFULLY maybe I will have spark back once replaced the main relay? What do you guys think?

IT'S ALIVE!!! A combination of things where found. Fuel pump relay, fuel pump, loose ground to ecu, and neutral safty switch. I drove it 40 miles down the back roads with no problems. Gonna give it a wash and get the tags current on friday.
