I have a Crx ZC DOHC engine that every time I start the car and start to drive it, it blows the ECU fuse under the hood. I replaced the distrubitor cap, the rotor and the spark plugs. My check engine light comes on every time and then blows the fuse. I was able to drive it for about three months fine after I did the engine swap but now all the sudden it started doing this. I'm checking for loose wires and seeing if its grounding out somewhere. Can anyone help?

I'd say your on the right track. sounds like maybe a wire rubbed on something and wore through the insulating jacket.

To save your self some time, open a service manual and trace the path of the wire from that fuse. That way you'll know exactly where to look.

 

Thank you for the help!!!

 

You said the CEL comes on before it blows. Well figure out what that CEL is. The ecu fuses doesn't clear the ECU, the hazzard fuse does. So the memory should still have the CEL.
