I recently replaced my integras engine with a JDM B18B1, I used my original throttle body(to have the MAP sensor) also I swapped 1 plug from my original wiring harness to the JDM one was a plug on the drivers side. Yesterday i finally finished up the swap and tried to start. Would turn over but plugs wouldnt fire(and it threw no CEL), since then i have Swapped distrubtors, checked ignition timing, checked valve tming, used an OHM meter to check to make sure distb was getting power, changed my sparkplugs and wires, since i have done all that now my car wont even turn over and it blows a 50amp ignition fuse in my underhood fusebox everytime i try to start it. I am positive ive got all wires right on the plug that I switched. When my previous engine quit I was in 3rd gear about 5500rpm and it just felt like I downshifted into 2nd and let out on the clutch. Car wouldnt restart would turn over but wouldnt fire. Does anyone have any ideas???
