How to get the infinite MPG without EOCing in a 2000 Caravan?

[101Volts]

I'm aware that I can make the van shut off the fuel injectors when the van is going fast enough (Such as down a steep hill going 35 MPH or faster) and I stick the transmission in Low. How can I make the injectors shut off at a red light, For instance? All that sitting uses up a lot of gas, Otherwise. I tried pulling the fuel injector fuse out with the van on but when I put the fuse back in the injectors didn't turn on again until I turned key off then on, So a fuse kill-switch doesn't work in this case.

The van is the 3-Litre model.

Also, What happens when I see the infinite MPG figure? Are the injectors off then?

Shut the engine off at red lights.

I'm asking how to do this without shutting the engine off. Can I switch the fuel pump on and off electrically?

If you turn the fuel pump or injectors off, the engine will die. That is what I was implying. Easier to just use the key or install a kill switch.

i'd go look for a factory service manual.

Thanks. I'm seeking a way to have the "9999 MPG" figure show up on the ScanGauge II (With the fuel not going into the engine) without shutting the car off and while keeping it in Drive, While also keeping the engine in good running shape.

I do have a copy of this:

Well I don't think there is really a way to do what you want other than killing the engine but you could shift into park and you might use slightly less gas than while in drive. Alternatively you could have your RPM at idle adjusted as low as possible which would use the least amount of gas but it would be a ton easier and cheaper to just turn the car off

To be specific, I'm asking "How can I put it in fuel-cutoff mode without it being in deceleration fuel-cutoff mode at a red light?"

But the problem is if you cut off fuel to the engine it dies, as in it turns off.

It stays on in deceleration fuel-cutoff mode in low gear.
