I just installed PI. I haven't hooked up the AIC box yet. I just put on the rail, and clipped the harness into injectors.

Now when I go to start it, nothing happens. My battery is good, lights and everything come on. But when I push the start button, everything just goes off and comes back on again.

The only things I remember unplugging were the MAP sensors(manifold and chargepipe), PCV hose, throttle body, and 2 clips on the black evil box. But I double checked those and they are all plugged in.

Found the issue. It was the starter motor power wire. It needed moved. I guess it didn't like its connection.

Maybe someone will run into this issue and this will help.

So, was it loose or is the wire/harness cracked?

I don't think the harness was the issue. I think it was the power wire to the starter. I couldn't really see, but I just reached my hand down there and moved the power wire and it started. It has happened a few more times since yesterday. I might need to get the TB off and play around with it.
