SC chimaera non starter after break down
Discussion
Broke down last Sunday as I was heading down to TVR south west open day first time in 3 years
Pulled away from a roundabout heading towards m32 car just cut out tried to restart turned over fine
But would not fire nothing
The car is a 4 ltr SC and it's running a Canems ecu, coil packs ect
Checked so far
Fuel pump primes ok
Fuel pipe of and fuel is there when primed and cranking
Checked ecu status red light on with ignition on turns green when cranking
Compression test done seems ok
There is a spark at the plugs but it doesn't look great to me ?
Battery checked and ok
Checked all pipes are on SC
Plugs were a bit black looking
Any advice where to check next guys

Doesn't the green light on the ECU with engine indicate the crank sensor is reading ok? Does on an Emerald...
I'd treat it to some new plugs
Yes I get a red light on with ignition I'd treat it to some new plugs
And a green light when cranking from the
ECU
But nothing all very strange but I will try
A new set of plugs there on the way

The front panel on all Canems ECUs are fitted with a twin colour status LED, this can be useful for a variety of diagnostic tasks. When power is applied to the ECU (ignition on), the LED should turn red. This indicates that the ECU has a voltage supply and it is simply waiting for a crank sensor signal.
When the engine is turned over on the starter motor, the LED should turn green. A green light indicates that the ECU has detected a crank sensor signal and has successfully located top dead centre of the engine.
It is expected that the LED may oscillate occasionally between red and green whilst cranking, but it is
important that this is not the case once the engine is running. A status LED which flickers to red when the engine is running indicates that the ECU has lost the position of TDC and is therefore unable to inject fuel or fire the ignition.
A flickering status LED can indicate a defective crank sensor arrangement, electrical interference or poor earth connections to the ECU itself... so you should check this carefully.
Remember it doesn't matter if its on the most sophisticated engine management system in the world or the most basic of carburetors, the engine is still just an engine, and engines naturally only want to do one thing, run!
As long as you have fuel of a mixture that's not insanely rich or lean, and as long as you have a spark occurring reasonably close to when it should in the cycle.... your engine will run!
Its back to basics... do you have fuel & do you have spark?
And in your case.... does the red light on the ECU turn green when you crank the engine?
Good luck with it

Yes all the above u have mentioned seem to be working spark at plugs fuel to the rail and a red light on and a solid green
Light when cranking I think the only thing I can check now is fuel pressure at the fuel rail to eliminate the fuel regulator
And new plugs
