I have read a lot about this error and most are having problems with map sensor that is not showing an error. The other sensors are bad as well if you are getting an error on them. You can check by unpluging the bad sensors and trying to start. If it starts then map is ok. If it does not them map is bad.

Thank you for the reply I will try a new map sensor Alan
