Hey all.

The 550 Was running great and we stopped for lunch then she wouldn’t start after that. Good spray from injector, spark plug sparking, air filter was clean as a whistle, and she won’t start…
Now she’s flooded right out to the point at got fuel coming out the exhaust side

Any sensors or anything to check first before tearing in to timing?


(Also found this ground wire hanging out when I went searching. Attached down bellow to the frame where the green grounds from the fuse box attaches, and comes up to the engine. Where does it attach??)

TIA

They all attach to the engine case somewhere..On Zs its usually one of the CVT cover bolts. That should have stopped everything.

Okay thanks I’ll take a look. Cover is plastic, so would it go to the other side on the engine casing somewhere? 

And what do you mean “should have stopped everything”??  Is this just a block to chassis ground or something more important?

Well if that's the main battery cable off, you wouldn't have anything..like spraying injectors, starter, spark...anything. Maybe that's one of the winch cables.

It doesn’t appear to be a battery main. Looks like one, but it goes down under the seat and attaches to the frame. I found a loose bolt as well under there this morning, attached this wire back to the engine block and she fires right up!!

But now my injection light on the dash is flashing but not in any particular pattern, just a constant on off every half a second. Any ideas or way to reset?
Thanks!

Just means there is an error from one of the sensors. It will stop when found and fixed. Because it starts and runs it's probably not something like an injector or fuel pump pressure. Maybe O2 sensor, TPS, IACV..something like that. Most service manuals show how to make the like flash the code or just get one of the scanners.

Thank you! I’m in Costa Rica so it’s more difficult and pricey trying to find a reader. I’ll have a look in the service manual I got from ya and see if I can find it. Thanks
