Evening wondering if anyone can help. I'm currently working on a kit car for someone atm with a tl1000s engine in. Atm I've been sorting the wiring out, was getting a c42 code as soon as I turned the ignition on, no fuel pump. Added a 100ohm resistor on the ignition today, fuel pump primed, c42 code disappeared until I turned the engine over and it came back. I've check the voltage on the cable the resistor is on and I'm only getting 1.3 v. Should this be 12? ive checked the voltage to the coils and its got 12v noting on the ground though. Also it hasn't got a temp sensor or atmospheric sensor which brings up c15 and c22 code, would this affect it at all?
