I just dropped a b18c into my 2k civic cx. I am getting no spark to the plugs. I checked all the sensors in the dizzy. turned out good. checked coil, icm, fuses. all good. I am getting no mil light to check for the codes. i was wondering is there any way to check the ecu besides substituting a good one. If not what other ecu can i use besides the p72 to check if it is the ecu. the engine is obd1 and car is obd2b. i used the cars harness for the swap and a ecu harness jumper. the dizzy clips for the b18c and cx harness fit right up but i had to wire the tach and dizzy powerwire. The dizzy powerwire from my cx harness looks like a 16gage and the one from b18c looks like a 10gage which i spliced both together. could that be the problem. not enough juice to the dizzy. or do any of the other sensors control spark. i would like to know all other before shelling out part of my rent money for another ecu. any help would be greatly appreciated.
