Hi everyone,
Few months ago I bought a 2007 fuel inyected 1500 SR3 as part of payment. Now I have decided to put the car ready for trackdays but unfortunately doesn't starts.
I'm in the proccess to check all parts potentially involved . Fuel pressure OK, plugs OK, new coils and spark wires installed OK, battery OK, the spark looks a little bit weak but is present. ........
Engine cranks but doesn't starts. A small pops sometimes but thats all.
Could anybody put a picture of his coils installation to confirm the firing order?
I'm searching on the Radical Manuals but there is no mention to this.
Any other ideas??

Thanks chaps.

Dear friends,
Not banana...... :-/
I filled 20 litres of fuel, added an aditional battery, new spark plugs......and.....nothing.
I'm not sure about how the fuel pump works on this car. Could anybody give me a short explanation?
When I put ON the main switch and the ignition switch I can hear the pump buzzing after the dash display has done the reset but then she stops.
If I push the starter the engine cranks normally but doesn't start and I can hear the pump for a while when I release the button.
I'm completely lost.
I will try a Iridium plugs today looking for some signal of life.

Cheers

Plugs smell to gasoline but are mostly dry and clean. Thats the reason to ask about the fuel pump. I really hate this kind of "elfs" .
Thanks mate.

Thanks chaps for your help.
I will check the loom from the ECU (MBE) to coils and will check the fuel pump and feed lines.
Can't understand why Radical goes for a submerged pump instead a external and more accesible unit. To dismantle all cockpit for inspecting the fuel tank and pump is really a nightmare.
As I posted previously the spark looks a bit weak and I decided to get a set of iridiums but after last attempt I have seen the sparks are mostly dry and clean which makes me to suspect a fuel problem.

Concerning to the Busa starting clutch, well it seems to run pretty well.
If I have no good news next time I'll do a call to RPE.

Have a nice day !!
