In Acrobat go to the Output Preview and choose a print preview colour space like Coated Fogra 39 or Euroscale Coated.
If it's a true spot colour you should be able to see Pantone 802 in the Output Preview Separations area.
And if it's a true spot colour it will be printed as a separate plate as Pantone 802 ink and matched to a pantone colour book.
If it's just for viewing onscreen then you will most likely never match the true colour of Pantone 802, if you're just viewing it on screen you should use the ink manager to convert the colour to CMYK on output to PDF, that might give a better result for onscreen. But make sure you don't confuse which PDF has the Spot colour and which has the CMYK version for onscreen, and you can do this with a descriptive naming of the PDF.
Go to the flyout of the Swatches panel, select the Ink Manager, and then check the box at the bottom that says "Use Standard Lab Values for Spots". Then, while exporting the PDF, make sure that you choose "No Color Conversion" as the Conversion option (in the Output tab). The spot color in your PDF should look more like what you expect.
I would like to thank Tom Eusrey, John Danek and Eugene Tyson for their replies and advice!
Tom's suggestion worked! The flourescent Pantone colour no longer looks dull in my PDF.
Below is Tom's advice:

I am a newbie to setting up files with flourescent colours to print and I appreciate any helpful suggestions to ensure that the job prints correctly.
I do have another question. If I follow Tom's suggestion and choose 'Press Quality' (if I am not supplied with any preset from the Printers) and export the PDF, would this file we suitable to pass on to the Printers? I have checked the Output Preview and Pantone 802 C is on a separate plate.
Many thanks again.
If the printer has a modern workflow then yes, it should be fine. If you need crop marks and bleed you can add them in the export.
As a sidenote, JCLFS,
it is fluorescent not "flour" like in bread... correct spelling will help people searching for threads about fluorescent ink issues...
Thanks for all the helpful replies and for the spelling correction!
That's a very interesting trick from Tom, and one I didn't know.
Keep in mind, though, that the appearance of a spot color on the screen is totally irrelevant to the printer who will print whatever ink is specified (I think Eugene mentioned this earlier). It's common practice, for example, to prepare one-color jobs that will be printed as spot color entirely as black or grayscale and simply specify which ink you want. This greatly simplifies file prep on that sort of file.The only reason to go to this trouble would be if you had to distibute this for on-screen viewing as well.
Shoooot... I usually have the Convert Labs always on in the Ink Manager, so that's why I didn't mention it.
