A really good discription of whats happening is very helpful.
Fails to start when hot, cold, anytime.. etc..
Intermittent problems are most difficult.
The key gives a fuel pump voltage until pressure is up, then the PCM allows a single prime for start.

Fuel pumps can be checked for volume flow at pressure by the return side giving volume.

Basically, replacing parts till the problem dissappears.
With your woosh, you had a firing out of time with fuel.
This engine may fire a wasted spark during exhaust cycle, therefore a whoosh.

I would start with the ignition module under the coil pack, then the crankshaft sensor in the harmonic balancer wheel.


Good Luck
