Engine off coasting on my matrix
I want to be able to coast with the engine off but leave the ECU, dash, & scangauge on.
From my searching it looks like what I need to do is make a kill switch for my fuel injectors. I went digging through my low voltage scrap wire box and found a 12v 40A relay that came off a HID kit. It is designed as a normally open circuit but I think I can make that work bu using a normally closed momentary switch.
My issue is finding the Injector fuse, any idea as to which one that might be on a 2006 Matrix?
All I saw in the fuse box that might be it was a 20A EFI fuse and a corresponding EFI relay. No hint as to what EFI stands for.
Ideas?
Hints?

Yeah, that dash reboots slooow...
EFI is electronic fuel injection, but that circuit seems to contain a lot of stuff normally, likely the computer that controls all the dash stuff.

The dash does boot slowly.
There is a EFI 2 (15A) and and EFI (20A). Which one does what?

Take the fuse out and see if the car starts.

that might work, but it will not tell me what else is on the circuit.

I did some searching for wiring diagrams. I found one for a 2003 matrix, my 06 should be similar but not exactly the same.
Anyone want to read these and give me a none EE description?
What does the EFI fuse do?
If these do not help I have 20 other pdf to sort through.

Page 2+3
4+5
6+7
8+9
Thanks!

Don't they come back online when you turn the key back into its normal driving position (II) ?
If I put it back to II too fast, even the engine will come back on !

Dash does but I do not like power cycling the ECU. I do not think that the SC comes back on (or it takes a while).

All I do with my Vibe is to stick it in Neutral, turn the engine off with the key, wait a few sec's turn the engine power back on with out hitting the starter and coast. This way I still have power steering while coasting, then bump start it when it necessary. My ScanGauge is in Hybrid mode so that stays on, car will coast quite a way.

I will have to try this on one of my mile long coasts and see what happens, it has been a while since I tried this.
