1991 honda civic wont start/no spark and lots of new parts
I have a 1991 honda civic lx and I have replaced the starter, ecu, distributor, wires and spark pulgs. I can get the car to turn over but will not start. I am not getting any spark at all but I have power to the distributor. I have checked for voltage and I am getting it and the distributer will turn. I am so lost can anyone please help me?

for free. 
Yeah there are some great sites that show you how to test your main relay (google it) if you want to check them out before you get a new one.
The easiest way (not always 100% telling) is take your main relay out (box about the size of a pack of smokes near the fusebox by your left knee), then take the plastic cover off. Once the cover is off look along the circut board for any weak connections or any burn marks, if its just a poor solder point you can resolder it easily. Burnouts can be a little more work.

you can even pop the main relay apart and see dry solder joints on it (which normally is the problem) if you feel comfortable doing that

I had a friend with a similar problem. Turn out to be the thermostat housing ground wire broke off the ring terminal.
