ok so i have a supercharged S5. here is the promblem. it wont start lol. i have spark, and fuel running through the lines. it just turns and turns and turns. i smell no fuel on the plugs. it starts on carb cleaner. i just bought a new ecu cuz i thought mine was bad but i guess not. can anyone help. im confused. thank you for any help you can give me

 

If you know that you have fuel through the lines, and it runs on carb cleaner, then you're not getting the injector pulse from whatever ECU you're using to drive it. That's the only thing left in the chain.
