steering pump fault

[jesfirth]

I have a griff 500 which has a retrofit PS system comprising a citroen saxo PS pump mated to a standard griff PS rack so basically the same set up as the T cars. it has worked flawlessly for 6 years but I now have PS working intermittently. it seems to happen when it feels like it - no particular speed or revs and its not just right or left hand corners so its not a rack or column issue.. it will work fine for 15 minutes then it just stops working then 2 minutes later it fixes itself.

I have checked and resoldered every electrical connection - the fuse looks ok

no fluid leaks and the rack is recently rebuilt and feels just fine when its jacked up with the wheels off

any bright ideas? do these pumps wear with age and become dodgy?.

thanks will try that - there is no ecu so that makes it easy. my challenge will be to get it to fail while I am testing it.
