TBI to TPI wiring problem
after i get my 5.7 TPI bolted and hooked up i now have a starting problem also no fuel pump.
i go through all of the TBI to TPI posts and i can't a conclusive answer.
some say i have to change the under dash harness and some say i don't !but the posts that say you don't aren't saying what i have to do to make my shiznit to work.
do i need to change my under dash harness or not?
i have a 89 5.7 TPI in my 91 TBI Firebird
Please for the love of Pete(who ever that is)i don't want to spend the summer wrenching on my ride while my freinds are riding around in theres!!!!!

You need to post much more information. How about telling us just what you did change? You cant just plug a TPI intake to a TBI harness. How did you wire the injectors, etc. etc.?
What did you do about the computer, the eprom, etc. etc. etc.?
