gsr starting issues
 

I jus got my 00 integra gsr back from the paintshop I drove it home and it drove fine all the way, I parked the car for two days and when i went to warm it up it started acting up...it cranks over n turns on but doesnt go past 3000 rpms then it it shuts off after about 10 seconds the fuel pump is going on and its getting spark, I changed the map sensor but still no luck...anyone have an idea wat it could be?
