engine won't start after pushing it

[andrew5826]

so I was in a slide probably around 6-7k for 10 seconds and all of sudden I lose power and the car straightens out. it's sputtering and won't hold an idle and comes to a stop

I start cranking it and it fires, barely starting. I try a few more times, firing less every time to where it eventually doesn't fire at all.

my mods include
jdl uel
perrin overpipe
Tomei type 80
k&n air filter
oft v2.0 stg2 uel 93 octane

I will note that I ran e85 2 full tanks of 91 before. when I switched to e85, I noticed the infamous crickets. when when I switched back to pump gas, they were still there so im guessing maybe the fuel pump died out?

Unlikely its anything to do with E85, the crickets are almost normal people have them for years no problem just annoying.

Any CEL light ?

Use your OFT to check for error codes

low fuel in tank ? possibly fuel surge air in fuel lines.

Bad battery?

On my previous car I had a battery short out internally on a sharp autocross turn (unsure if I spun myself, or the battery causing a system shut-down caused it) and it behaved somewhat similarly, though in my case it wouldn't turn over on its own.

I've heard in some more extreme spins the ecu thinks it crashed and cuts fuel.

First thing id try would be to disconnect the battery for a bit, next if that didn't work maybe throw the stock tune back on.

Sounds like a fueling issue to me. Does anyone know if our cars have an inertia switch that's supposed to activate during accidents?

"(3) A fuel cut control is used to stop the fuel pump when any of the SRS airbags deploys. In this
control, if an airbag deployment signal from the air bag ECU assembly is detected by the ECM,
the ECM will turn off the circuit opening relay. As a result, the power supply to the fuel pump
control ECU assembly is stopped, causing the fuel pump to stop operating. After the fuel cut
control has been activated, turning the ignition switch from off to on (IG) cancels the fuel cut
control, and the engine can be restarted."

I think it may have something to do with this. I was in quite a fast and sideways slide. battery was fine as I cranked it for a couple minutes. no cel, tried reconnecting the battery, half tank of gas..

so i got the car towed to my place (free from subarus awesome road side assistance that I didn't even know I had until the tow truck driver mentioned it) and I was feeling pretty down. get home an hour later (car died for 2 hrs at this point) and tow driver says something along the lines of try starting it, the ride may have wiggled the fuel pump. I start it and it fired right up! I couldn't believe it. exhaust smelled a little funny but otherwise no problems. ended up having a nice chit chat with the driver while getting a free ride home.

Nice to see a happy ending!

Could it be vapor lock on the fuel? Was the engine hot. Anything hot like a header near a gas line?

From the time the car died on the track to getting towed home and successfully starting the car, how long would you say the total incident time was?
