Default 2001 subaru just shut down

Hi all.
My first post and my first Subaru. Hope this is the right section to post in.

I just bought a used 2001 L.L. Bean edition Subaru Outback with 180,000.
I was driving along slowly (maybe 25 mph.) and the engine just shut down.
It would not restart, and didn't sound quite right while trying...a little shaky compared to the previous smooth start.
I thought timing belt broke. Had it towed to a mechanic who later called and told me there is no timing belt...most likely an electrical problem.

Hoping someone can shed some light and help me toward repairing this my self.

No timing belt? I hope your car is an H6 or that mechanic needs to back away from your car.

What engine is in it?

Assuming you have the 2.5L engine, of course it has a timing belt ... and it may have slipped a few teeth. Find another mechanic if that's the case.

Yes H6 engine. Has timing chain i guess, and apparently not likely to break.

I was thinking maybe a fuel pump relay or possibly engine computer.

Best guess fuel pump, pump relay, pump shutoff switch.

When you turn on the key can you hear the pump run?
Might need someone to turn the key while you stick your head near the tank.

Yes i hear the fuel pump when i turn the key. But my best guess is also not getting fuel. Just had the tow truck drop it off at home. It is H6 3.0.

Cranked the engine a couple of times. Seems like no fuel. Strange that it just shut down while driving along and wont restart.

I bought an OBDII and tried to read codes. Got No Codes. Which lead me to think the mech. erased the codes accidentally.

I found a disconnected pair of green connectors under the dash above the accel. pedal. I plugged the together and turned key...fan ran, check engine light kept flashing, etc. Also sprayed starting fluid into air intake. The car STARTED and ran for a sec. Disconnected the green connectors all returned to normal on check engine light.

Read new codes, 8 codes, mostly o2s related. One was veh speed sensor malfunction.

Would malfunction of veh speed sensor prevent fuel delivery?
Where is vss on 2001 outback L.L.Bean Edition?
TIA.

Maybe a crank sensor or o2 sensor? Both cheap to replace.

I think the green connector is a pre-delivery jumper the dealer unhooks.

I don't think VSS or O2 sensors will keep it from running.

I think you need to check for spark (harder on the H6) or fuel pressure (cheap way- have co-hort turn key on then press the center part of the schraeder valve on the fuel rail while protecting your eyes, of course).

The ether test shows it probably has good enough spark to run.

Even if the crank sensor is bad you'll get fuel pressure when you turn on the key and the engine runs, I'm pretty sure.

Im pretty sure spark is good as I can start it by spraying starting fluid into the air intake...it just wont continue to run, of course.

I learned that the previous owner had the "steering rack" replaced with the wrong replacement. The vehicle will over-steer in a parking lot, for example, by turning the wheel too sharply. This apparently broke some contactor device in the steering wheel (over turning the wheel). Consequently the horn, cruise control don't work, and the airbag light is on.

I think the vss is somehow related to the steering rack on this model, and it too is now disconnected or broken. I think the vss tells the ecm to deliver fuel and regulates ignition. Am I wrong?
