I took a 92 civic cx engine and put it into a 95 4door se now when I finished I realized that the map sensor was different cause of the wiring so I took the original engine harness from the car and installed it on the older engine . fine and dandy went to start the car and it would not start . it turns over and the fule pump turns on like normal. seems not to be any spark or something . I am totaly stumped I have swaped motors before pluged everything in and no problems . but for some reason this engine wont start . is their anything different with this engine are the sensors wired all the same or do I need to change something . I havent hooked up the rad yet so their is no coolant in the system wil this make the car not start . someone please help me I am ready to burn this car LOL !!!

no spark? check the thermostat ground (on the thermostat housing)

You have to use the original map sensor as well, not just the wiring and also, the original ECU.

I checked and cleaned ground wire on thermostat and I used the new map sesor and ecu still nothing any other things to look at
