But you know how that goes.
Yeah I have seen the stranger from GM... LOL
1993 was the last year for the 3300 V6... As all of the 3300 powered cars would be powered by the new 3100 SFI V6 in 94...lol
AC Delco PN# D1977A was used from 1990 - 04 as listed by AC Delco
AC Delco PN# D1946A was used from 1986 - 92
The 93 does have the D1977A listed for it... Wondering if they keyed it the same and left certain pins unused for the 3300?
Heck 93 might be an odd ball year... The 3300 wouldn't need the 18x'* pulse to run...
If anyone finds out please let us know... This may be good swap info fo the older 3800'* as well...
