What are code scanner #'s 87 & 11?

I have a code scanner for my 5.0 but I cannot find the code book that came with it. Can someone please tell me what numbers 87 and 11 mean? Thanks.

11 mean's ok or done. Not sure what 87 means off hand, my book is at my garage space.

Sorry to steal your thread, but maybe this will help you as well. Does anyone know of a good site or reference for all DTC's, at least on the 5.0's?

Hi,
According to my Ford code reader book the definition for #87 is; Fuel pump primary circuit fault.
Good Luck.

Thanks. Can anyone tell me how I would go about checking that out or fixing it? My car runs great 90% of the time but every once in a while the engine just cuts off, then it starts right up. Could this have to do with my fuel pump?

Try the fuel pump relay before you start ripping stuff apart.
