Some reason your fuel presure isnt dropping once you try to crank the vehicle telling the pump to kick back on from the initial priming.

That sounds exactly right. The fuel its priming isn't being dumped to the cylinders, which would be why my plugs are always dry.

Is the car parked outside over night? if so squirrels or rats could have messed something up making a nest for winter. Check your wiring harnesses under the hood for signs of damage.

All wires seem to be good. No evidence of any tampering or damage.

Is that a chipped key? Can you try a different set?

No, just a regular key. No chip.

There's stock fuses for anti-theft.

I don't understand why I can have good pressure at the Schrader valve but all of my plugs are dry. The only thing between there is the fuel rail and injectors.

Pull the fuel rail and see if the injectors are actually flowing fuel. Also check to make sure all the connectors are tight.


Just thought of this. Check your MAF wires and such. It may be the computer isnt registering any air therefore isnt flowing fuel. It may think its running rich and therefore is trying to lean out the fuel.
