Adam,
You may have already tried these. But, I'll toss 'em out anyway... I've had
this happen a couple of times, and it's very frustrating because nothing was
touched other than engine swap. 1. Plug contacts (female pins) on AFM plug
may be pushed into plug. 2. Loose contact at hot side of coil will do it...
sometimes just wiggling the black lead will get the noid light to fire...
pointing towards corrosion in the connector.3. Terminal 88y is most common
at double relay plug ...pulling out of white connector going into double
relay,or backed out a little. 4. Corroded wire in power supply box (left
rear of engine compt) is rare but has happened 5. Depending on model you
have, you may have a bad electronic ignition control unit if you're model
is equipped with one. You didn't mention if fuel pump was firing so I
assume it was... so that pretty much leaves out solenoid wires being
swapped... on some after market starters that would make a
difference---Goodluck please let me know what you find---Jon
