'They said' is not directly acceptable. Got a read/print-out from the EMM?
Starting 60% is not either acceptable after a repair - it should start 100%!!
I'm not quite sure they got it right.
To have an opinion on that, I would need the readings from the EMM, stored soft codes, ev. hard-codes as well as voltage readings when cranking and engine not starting. Add to it all, perhaps the most important: the cranking RPM??????????????????????????????
