My Delorean stops running

[Iceguy]

Made a little head way - here is what I have so far. I'm guessing nothing has been done to the gas tank.

I also dont understand - pressure on the air plate ?

[Dangermouse]

The airplate is that silver circle in the center of your second picture. You should feel resistance when you push it down after the engine has run.

[Iceguy]

Ok after shutting off I pushed down on the airplate. It had pressure, but would not restart.

Did you also check one of the plug wires to see if you still had spark?

Been doing some tinkering on my car and think my problem is somewhere in the fuel system. Either the fuel pump, or some crud in the line somewhere. I was wondering if someone can tell what this box by the fuel sender does ?

[DMCMW Dave]

Tankzilla fuel gauge sender. Not the problem.

Took out the fuel pump. The tank looks clean. I unplugged the wire to the pump and checked the electrical connection when I turned the key to on - 0 volts. But that does not explain why it will run 3 min then shut down.

Fuel pump only gets power when the engine is running. Most RPM relays prime the pump (power for 1 second) when you turn the key on,

I was trying to narrow down where my problem lies, but I came up with a lot more questions. I know the fuel pump works - at least I can "feel" the gas going thru the line when running and now understand why it shut off when the car does. I tried useing a "jumper" to power the pump, but it didnt work. I am still trying to work out if it is electrical or mechanical.
Now the battery died, so I have to charge it.

Hey Ice,

It might be worth checking the connections on and around your inertia switch. That little gizmo is intended to shut your fuel pump off if your car is upside down. Maybe something with it is causing the intermittent fuel pump shut downs?

It is located under the driver's footwell. It might be screwed to the same bracket as your lambda/service counter, or it might have been relocated to the left, on the inside of the left front fender area. Looks like this:
