does any one know why my tst box does not fuel with a new map sensor i was told to clean my map sensor about two years ago when i started having a problem with it with no power leaving a red light cleaning it solved the problem but now cleaning it does not always work so i put in a new one and now it wont fuel at all put old one back in after cleaning it an away i go just as if no problem at all

 

Might be a bad sensor out of the box. Take it back and get another one.
