Explosion, now no start.

Good instincts on looking at timing. the timing was all set correctly: cams, crank, CPS installation, but I found two wires reversed on the connector to the CPS.

My understanding from the TEWD is that the engine harness connector is supposed to look like:

Blue Red
pin1 pin 2

Black Yellow
pin 3 pin 4

I had black and yellow reversed when I fixed the worn connector. How i had any spark at all I still don't understand.

Now the coil packs are still confusing. In the tewd it doesn't clearly say which wire from the igniter goes to which coil, but labels the wires
IG1 to coil pack connector pin 1,
IG2 to coil pack connector pin 2
and then the third wire to pin 3 isn't labeled with a moniker
coil pack pin 4 is B+ common.

Fixing and putting engine back together. will report back.
