there are no wires to the air box of course, so I imagine you mean the air
flow meter,
and what you are saying is you cleaned the connections to the air flow
meter, including that anti-vanagon syndrome adapter harness, is that what
you're saying ?
  I'd go looking at the basics, like power to the ecu coming out of the main
relay,
make sure power to the fuel pump is happening, that there is fuel pressure,
It's easy to check if ignition is working while cranking it over.
It's easy to check if there is injector pulse to the injectors if you have a
noid light.,
also......connections to the temp sensor for the ecu.........

It's handy to have a fuel pressure gauge too, just to make sure FP stays
where it should when it stops after 20 seconds.
Start every time but die in 20 seconds makes me wonder if the fuel pump is
staying running after the initial 'key one' pre-run period.
Of course everyone just turns the key to 'on' first to confirm the fuel pump
does it's pre-run thing, and not just straight to 'start' , right ?
