Joe,
Sounds like your new fuel pump isn't adjusted quite right. If just a little
off, it will often pump a few times and then stop or pump erratic. I've
found that sometimes new SU fuel pumps are not adjusted properly when you
get them and have had the same problem with replacement point sets for SU
fuel pumps.
What you should do is check the points adjustment and the diaphragm
adjustment as delineated in the attached page 261 from Norm Nock's Austin
Healey Tech Talk book. I've placed a little arrow beside the two
instruction sections. These two items need to be adjusted pretty much right
on. You'll need a feeler gauge.
Hope this helps.
Vrooom vrooom,
John
