Need help. Have an 89 crx si. I am swapping a Zc out of a 1989 integra.I am using the engine bay harness from the zc. I am using the ecu from the 89 crx si. First, will it work. So far it has not started, or should i use the intefra ecu. If so do i need to change anything in the wiring. Pls Help. Im racking my brains. With the current config as i mentioned above. I can not get the ecu red light to go out. the fuel pump will not kick in. I have changed out the main relay, as i have heard they go bad. No effect. If a jumper i can get the fuel pump to come on and boot the ecu. But it still shows red light. any help would greatly be appreciated. I have owned 6 hondas, but first time at swap.
