starting/not starting issue
none- daily driver 05 base, manual with stock motor, headers, x-pipe and corsa exhaust
Everyone now and then when I hit the start button it just cranks (no codes, no dimming lights). I hit stop, hit the button again and it starts. Every time this has happened, it only takes one stop then always starts on second push.
Any ideas??

I had a truck with a similar issue, and it was the check valve in the fuel pump. It would let all the gas bleed out of the lines, so if it sat for a bit, the line would empty and then it would take several seconds of cranking to get it started. It would usually go thru the first crank cycle of a few seconds, and then immediately start up second time I tried to start it.
If I turned the key to run and waited 3-4 seconds, then tried starting, it would start right away everytime as the lines had enough time to pressurize.

This makes sense, so to test it, just hook up a fuel pressure gauge to the fitting at the engine and then let it sit overnight and see if it keeps some fuel pressure or if it all bleeds off.
You can leave the gauge connected and keep an eye on it.

Yep, my 03 has done this for 40,000 miles.
Simple trick, cycle ignition 3 times letting it sit in the on position for 5-10 seconds. This builds fuel pressure so it fires right up without putting any undue wear on the starter.
OP check fuel rail line pressure and see if it bleeds of to zero rapidly.

With headers, I suspect a bad starter or solenoid.
I had an intermit starting problem on another car and could not replicate it at the dealer. Finally, after it failed in my garage I had it towed and they replaced the starter/solenoid.

I had the same problem. Easy fix, just a bit time consuming.

But the OP said that the car always turns over, it just doesn't catch and start. The starter and solenoid are working right. Their job is to turn the engine over, responsibility for actually starting lies elsewhere.

Hook a fuel pressure gauge at the rail.
1. A quick bleed off is most likely a bad check valve.
2. Raise fuel rail with injectors and test for a leaky fuel injector.
I wonder if the OP smells fuel at startup?

All sound advise.
He can also take vacuum line off pressure regulator and look/smell for gas.
