I have a 1989 honda crx si and I recently switched out the wireharness and during the removal of the old harness the owners before connected the starter cable that receives the 12 volts directly to one of my ignition switch plug wires that's black with a white stripe. Now that I replaced both ignition switch plug and harness my car won't start. My lights from my dashboard light up but when I tried to start it now power. Where is the starter connected to where it receives power when the key is turned to start the engine and what can be a problem it won't send the power?

 

What harness did you replace and why?

 

Replaced the main engine harness because the old one was modified which was causing a short and my car to shake and turn off.

 

check your fuses. Are any blown?

 

I know im saying what youve probably read already but there is a ground on thermostat that runs off the harness, since you changed out your harness make sure you hooked up you ground wire and check all other ones.

 

check the ground wire that goes on the thermostat housing.

Very important. Grounds the ecu

LOL, ^didn't read the post above me.

 

Smart thinking lol
