OK having a problem with a toyota 7FDAU50 with a 13Z diesel inline 6 cylinder. had to have the injection pump rebuilt, now upon installing the rebuilt pump it has a rough idle. surges until you give it a hair little bit of throttle and then it smoothes out. when i timed the injection pump with the rest of the timing gears i was able to line up all the timing marks (0,1,2,3) except for the injection pump. #2 on the injection pump and idler gear had to be advanced by 2 teeth inorder to get the ~.060'' at TDC for book specs. when aligned all together straight up exactly as book calls for the unit will not start. advance it 2 teeth and start right up. BUT, after it starts and you give a little throttle bump, on idle down it sometimes kills engine and sometimes not. sounds like a timing issue still. tried adjusting the pump a little bit with no such luck of getting rid of the up and down rough idle. please help with any advice!!!!
