I had Beckman check both ETA's on the V12. They cleaned them and checked them electronically and said they were fine. Turns out the right side ETA had a bad potentiometer, dealer pulled the codes after I replaced a couple more bad harness's. Beckman's way of testing is to plug the ETA's in and bend the shit out of the wiring harness and connector and if the read values don't peg the meter it's fine. So I'd be looking at the pump being bad again. They usually warranty their stuff for a year.
