I was driving down the road in my 2001 montero and it just died. Scanner Wouldn't communicate with the vehicle checked around was told to change pcm. So bought pcm,immobilizer and the key all supposedly out of the same vehical. Installed them all and still nothing. Oh the fuel pump doesn't come on and has no spark. Any idea's the wife is wanting her garage back.

 

Where did you buy your PCM? There are a number of things it could be. Have a knowledgeable mechanic scan your Montero although an oreillys or auto Zone should be able to do it. There should definetly be error codes for that
