Re: how do reset ther ecm?
It's definitely been addressed before. But,...By resetting it all that will happen is it will clear any stored error codes. To do it, there's an orange wire with a connector that looks like an O2 sensor connector coming from the battery. Disconnect it for 10 seconds, reconnect it. Reset. If you can't find the wire, you can just pull the negative terminal off the battery for 10 seconds or so.
