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?

being an interference motor...i think he'd of heard some carnage instead of it just dying quietly.
