Having problems with your 1989 Honda CRX ?
When I turn the key over my '' check light'' won't light up at all.i need to do a smog check, but because ''check light won't light up i can't even start a smog check .i changed the small light on the back of gauges and the ecu i so.k. any ideas what the problem is?
The wire from the bulb to the ecm needs to be verifed good, a easy way is to find which terminal number the ck engine light is on, and see if that pin provides a ground when the key is on. if it does, the wire may be bad, if no ground, the ecm is bad.
