I have a 2001 Honda Civic EX which had the D17A2 Engine with a rod knock. So me and a buddy grabbed a Engine from the local junkyard. It happened to be the D17A1 Block from a LX. After reading a bunch of the forums it appeared that as long as we kept the Head from my EX (VTec) and since my ECU is a EX (VTec) it would work. So we got a D17A1 Block with my D17A2 Head back in the car, everything is hooked back up. Were getting the engine to crank but not start. We checked fuel lines and fuel is pumping to it. When we try to start it after theres a bunch of clicking on the passenger side which i assume is probably the computer. We tried pulling the ECU fuse to reset the computer along with most fuses under the hood. Before the swap the car started fine just had a terrible knock. Any ideas?
