Sons 300m and I need help please!

so we have air, fuel, and spark on all 6? i had a 3.5 in a concorde, and it lasted through 200,000 and sold it to a kid at work. Still going strong...
that should have an IAC, MAP, and TPS. any of which could be sending a BS signal to the computer. Have we tried to slightly crack the TB by hand and see if it responds to some air at startup? Yes we have, no change.
I would think if any of the sensors are gunny sack, IAC, MAP, TPS, etc, I would be getting some code somewhere.

being an interference motor...i think he'd of heard some carnage instead of it just dying quietly.
The only thing I can think of here is that the cam that does not have the cam sensor is off by 1 or 2 teeth. From what I have read, that could happen without interference.
