Hard start after cold snap.

[Axoure Dragonkin]

1992 240sx with 96+ ka24 also using s14 intake manifold

So we just had a cold snap here in Texas with some snow after a week of 70 degree weather.

2 things happened.

My dash cracked.

And I started having starting issues when the engine is cold. I haven't tried the diagnostic procedure yet. I had just put my cold air intake back in the previous week. I've never had starting problems before.

Starter sounds fine. I'm guessing I'm losing fuel pressure while it sits. Leaking injector or I'm not letting the pump prime enough before starting.

Any suggestions? I'll post up the results of the diagnostic when I complete it.

I got stopped on #3. Check IAA valve. When pressing accelerator pedal fully, can you start the engine? Yes = Check IAA valve and circuit. No = Continue.

So yes, I was able to start the car with the pedal all the way to the floor. I thought it was suppose to cut fuel when starting it that way. For reference, after I do start the motor, I will have no trouble starting it a second time. This only happens when it sits overnight. So it could still be a leaky injector.

I will test it when it warms up a little. I have a unit on my s13 manifold that I can swap out if need be.
