Abs runs in park.
Hi I have an 89 xjs, and recently the abs and brake light come on when you hold the pedal roughly 5 seconds go by with your foot on the pedal and then the abs pump starts running and you can feal the pedal pulsing. checked fluid, checked codes, no codes, bled brake system. checked and adjusted brake switch, and swapped out the accumulator and pressure switch. still have the same problem. any suggestions?

Do you know what pressure the system is sitting at? The pump operates when pressure drops to 140bar and switches off at 180bar. Have you checked for fluid leaks?
Both ABS and Brake warning lights on indicate system pressure has dropped below 105bar and ABS has been switched off to the front wheels. If this is actually the case there should be no continuity between pins 9 and 10 of the ABS ECM. This is controlled by the pressure switch which I see you have replaced.

Of course great advice and most certainly to do before you buy anything else
