if it is code 8. tdc. take apart the dizzy and fix it. or get a new dizzy. that could be your problem. did you check for spark.? you prolly didnt need injectors either. coulda saved yourself money. fix the code first.. check for fuel. spark. all grounds good.

its not hard. you just have to have another sensor to put back in it.. any sensor from any honda dizzy should work. or if you can get another dizzy try that .

bro its prob the dizzy wiring for the TDC. i had an issue with the CKP sensor wires were switched around. triple check to make sure, check from the pinout on the ECU to the dizzy, thats where my problem was. I made a jumper harness for the 2 injectors and 2 dizzy wires, and the 2 ckp added wires were switched around.

anyone have an idea what sensor it is i know the one all the way in the back is the crank angle sensor that you add the wiring for. so there are two left the one right after the rotor or the one right before the CAS. any ideas?
