5VY R1 misfire?
richiekuk - 27/4/13 at 05:32 PM

I started the fury today, and it started to sound like a machine gun, now it won't start.
All 4 plugs are dry (thought maybe a plug had died).

Any ideas?
Cheers

How long since you last started it, could be old petrol, sounds daft but it does happen.

I've seen similar before and it turned out to be a failed coil driver in the ECU. Engine miised briefly then wouldn't start (and it cuts the fuel).

Have you got the R1 clocks? If so you can test fire the coils in turn (you get 5 sparks ) to check them and the ECUdrivers by using the diagnostic mode. (you can also test fire the injectors)

In the example I saw we got no spark on #1, tried swapping coils and the failure stayed on #1. We then swapped my ECU onto it and it ran.

Thanks for the input guys.

Turned out it was fuel. My fault too. Fuel is definitely best left in the tank, not on the floor.

Massive fail from myself!

Could be anything, so many things.

You were pointing at a possible noise from the fuel regulator earlier....? so has the fuel pressure died?

By the way, dry plugs (as you may or not be aware) don't necessarily mean simply a lack of fuel. The ECU will cut the fuel (is the pump relay firing?) if it can't find at least 3 coils to fire, or many other things. If the fuel pump relay isn't being fired (that nice 'click' after the ECU boot and the STV's shuffling back and forth), the ECU isn't happy with something fundamental.

The R1 can be a real pig to start sometimes, it doesn't like fouled plugs at all. When you've found the problem, might be worth changing the plugs as a matter of course.

Come on, 'fess up... It's good for the soul.

What had you done?

Lets just say the hose connected to the fuel pump, should be connected at all times!

Oops!

At least now, i know the symptoms of running out of fuel!
