Wrx starts up but then turns off
 

So I had an issue today with starting up my wrx. It would turn over and startup but then turn off after 1 second. I tried this a few times and it kept turning off. I then held the gas pedal down for 10 seconds at around 3000 revs. The car stayed on but turned off when I let go. I did it again at 4000 revs for 15 seconds and then the car stayed on and drove fine. I also tried starting it up again when I got home and it started fine. Is there anything that could relate to a cold start up and the car not wanting to stay on? :confused:

What fuel are you running?

What mods do you have?

Do you have a Brant?

Yep

Idle control valve.

My mistake, it has iacv not e-throttle.

Carry on... :)
