We have been building this car for a while now, 96 z28 a4; pacesetter lth mild cam b&m shift kit b&m stall and k&n cai! We sent the computer off to pcmforless for a tune! We got every thing back together just to find out our fuel pump was bad so after going thru that nut roll we thought we were good to go..... Well it still wont start!!! A mechanic friend did his thing and said we are getting all the "info" at the computer but were not getting anything to the injectors!! He said that he thinks its not getting the right juice to the injectors which means the computer is bad!!! How do we comfirm if the computer is good or bad?? We also tried to see if there were any codes that was preventing the injectors from firering but we cant get our code reader to work!! it works on both my 02 Z28 and my dads 01 Ram! Any and ALL help and other suggestions would be appreciated!! Btw we did cheat and used starter fluid to get it started and man did it soound bad ass for 5 seconds, well 10 seconds cause we did it twice!!
We also had a thread on abother site but want to see if anyone here might be able to help aslo!!

Have you asked pcmforless what they think? They may be able to tell you where to check. Otherwise you're probably looking at needing either a tech2 scanner to see what the pcm is doing, or a factory service manual so you can pinpoint where exactly the wire is going from the pcm to the injectors, so you can check that connection to see if there is any damage in the connection itself or in the pcm.

A tech2 scanner is the scanner used by GM technicians at a GM dealership. At this point your cheapest option may be to just pay the 90-100$ diagnostic fee for them to tell you what's wrong.
