complete shutdown while lapping
1990, 1.6, gt2560r, MSII, 11psi. driven responsibly on street regularly with no issues. at the track, got 6-7 laps out of it before the water/oil temps started climbing so did 2 cool down laps and then parked it while idling/heater cranked. got back in after 5 minutes or so and after 2 laps engine shut down. coasted out through pit exit and that was it. cranks, no start. towed it back home and this morning it cranked, started for 1 second and died again. will tow to shop tomorrow.
I don't hear the fuel pump humming with ignition on. can a mortally wounded fuel pump gather enough energy for a one second idle per day? and yes, I will be upgrading the rad and doing ducting. |
Fuel? Spark?

fuel pump.
Fuel pump in my OTM died, it would start, idle like crap for half a second, then die. If I waited 15 minutes, I could get another half second out of it. |
Also seen plugged fuel tank vents and pickups do this.
|
busted crank sensor? it happened to me, easy check. car would start run for a couple seconds and die.
|
no word from shop till tomorrow.

Gah why are you bringing a turbo'd miata to a shop?!? Would not trust...
You could also check the crank pulley, they like to slip/break/snap/loosen. |
sloppy wiring by P.O underdash. F.P wasn't getting power due to short. all good.

Not hearing the fuel pump is a "clue." Apparently the shop you used is not clueless. |

Glad your resolution was simpler than mine.
