I went through several new ones before finding one that worked. Also be aware there are two wiring setups for them, the pi outs are different for later years.

I'd be testing, rather than parts chucking. I doubt that a Duralast is better than any other low priced unit.

OP, et al: A big surprise to me - well maybe not THAT big - was the term "Infant Mortality". When you delve into the statistics of failure rates, you discover the TWO periods in the life of a (part) where it is most likely to fail are (1) when you first install the (part), and (2) after it reaches the end of its life expectancy.

Bottom line? In 50 years of fussing with cars, it's been my experience that If one is to replace a number of components as a "matter of routine maintenance", it is a good idea to either spread them out by putting each component in service long enough to make sure it is working properly and doesn't crap out before it has had time to even collect dust! OR! be prepared and have the equipment on hand to test and verify the performance of EACH of the newly installed parts! Note: As aircraft pilots know, the two most worthless things in aviation are 'Altitude above me and runway behind me!" AND, the same can be said about new parts: "(the problem) cant be (you name it) because I just replaced it!" Gotta VERIFY. Never assume (it is the icm...or whatever).

Well, that is my "helpful hint for the day". I've been fixin' chit for 65 years of life - love doing it, actually! (Yeah, I know...its a sickness!) So, please don't take offense to anything I offer. I just like helpin' folks with stuff, and Corvettes (C4s) is my passion!
