Did I misunderstand? You rebuilt the TBI engine and used vortec heads and efi? So the ecm cant see the crank position and is probably operating off limp home mode?
Hello Kacy, well not exactly, i used the plastic vortec cap of a 1998 tahoe, with crank position sensor, same tahoe the heads came from.
Let me edit my post, in order to fulfill the answer: I rebuiled the L05 TBI engine, used L31 vortec heads with all the top end from vortec, meaning i installed CSFI, but changed the spider in CSFI for for the one with injectors on the ends "AC DELCO 217-3029 89060440", installed the "Comp Cam 08-467-8". Wiring from vortec and the PCM "Black Box" from Vortec engine as well 1997 or 1998 not sure, but i think 1998. Hope this makes it more clear, if not, i can make it as a list of parts i used for my build.
Regards.
