Code:
SSP1CON1.5=1                                 'ENABLE I2C #1
SSP1CON1.3=1                                 'SET I2C#1 FOR MASTER MODE
SSP1CON1.2=0                                 'SET I2C#1 FOR MASTER MODE
SSP1CON1.1=0                                 'SET I2C#1 FOR MASTER MODE
SSP1CON1.0=0                                 'SET I2C#1 FOR MASTER MODE
fixed my problem. Apparently the PBP I2C command doesn't do any setting of this stuff for hardware I2C pins, so must be set.

Thanks for your help Mark.
