No pulse from Yellow Tach wire
I just put a Holley Pro-jection 4D 900 cfm kit on my 86 IROC. It starts but will not idle. Everything checks out, except I'm getting 7.4 volts at the yellow tach wire. I had a friend hook up a machine and it was not getting a pulse. What can I do to fix this or get around this?
