No Boost!

After replacing a coil pack I no longer have boost.

I took everything apart and put it back together, still nothing. I couldn't find any pinched hoses. Only thing was a pinched wire from the ignition pack, which is no longer pinched. Is it possible that cable is now broken? Any way to find why the car won't boost, like if a sensor is throwing an error, or is it just guess work?

I would check out if some KPA sensors have haven't been left unconnected or bleeding the I/C system would be ideal. Get a star scan in MEFI to see for any codes

I bled the IC system. It took a little fluid but quickly topped off. There was a froth in the IC, but it seemed to dissipate.

This is also not just slow, as in a bad IC pump, but no turbo at all. The schrader valves did weep, so the pump appears to be running.
