So after 2-3 weeks of the recent blower install, I've come to a snag in the tuning. Engine will crank but she just wont turnover. Replaced the battery (first since 06) but still wont turnover. Replacing ignition switch tomorrow, but still don't think that's the problem. Any suggestions from you fellow gear heads?

Sounds like a fuel over ignition issue to start. any inline fuel pumps installed? Backwards?

Like dj said.....everything is stock. The problem is so weird it has Joe (leftcoast 32) thinking about what it is. The thing that gets me is that it worked fine 2 days ago. Last night it had knock retard on the same tune and now today it just wont run. Can't be bad gas......already went thru 1/4 tank and it was fine.

Check the wiring for the fuel pump booster, it may be a bad connection.

With no spark it would be the ignition switch.

The thing is with no changes in the tune other then airflow for an idle issue it started having all kinds of problems.

Update on this. OP messaged me and said it was the manifold (blower) bolts. They backed out or came loose I guess. From what I understand everythings working again!
It was also the ground on the cylinder head, passenger side.
