Acura Repair: acura integra, acura integra, stock engine

Question
I have an acura integra we just replaced the stock engine with another stock engine and drove it around it overheated i believe then we shut it down and let it cool put more water and coolant into the engine and the check engine light is still blinking very rapidly and the engine sounds like it wants to turn over but doesn't have a spark or something we cant figure it out so if you could give us suggestions it would be appreciated

Answer
CHeck the thermostat to make sure it is opening.
It should have a bleeder valve around the thermostat housing. Bleed the system before running using the bleeder valve.
After this, check the compression and timing.
Once that is done write back and we can go from there.
