My Miata left me stranded for the first time ever last night. Now trying to fix it. It's running full standalone MS3X with a turbo.

Issue:
Car turns on, battery full, fuel pump runs as usual, but when turned to fire nothing happens.

Symptoms:
Has happened intermittently before. I would come to the car and hit the key with the same issue the first time, then on the third time it would fire right up.

Once about a year ago it gave me the same issue - would not crank at all. After pushing the car around to get it ready to pop the clutch it ended up starting right up.

What could this be? Crank trigger wheel? Starter selanoid? Clutch switch?

Another odd occurrence is that for some reason recently when I push in the clutch my parking brake light sort of flickers on. I have not changed anything else to cause this.

 

Could be dozens of things, a lot of stuff has to be "right" - or at least close for it to start.

Does the engine spin over at all?

Can you post a log of it trying to start?

 

As stated above no cranking so I can't check for spark or anything.

I have to bring my computer down, the car is sitting in a parking lot now.

 

Don't bother with the laptop, you have an electrical problem, not a mega squirt problem at all.

A common problem with higher mileage cars is carbon buildup in the ignition switch, mine was doing it so bad the wiring actually got toasty... I had the EXACT same issue. You may want to search I think there is a DIY on it here somewhere. I totaled the car before I actually got around to fixing it.

 

Just found this thread which outlines my exact problem but didn't pose a solution:

From what I see it did. Bypass the clutch switch and see if that does it
