I'm beginning to wonder if I will ever get my G13B conversion started. I spent all day today trying to make progress. Dave at DMW Motorsport was super helpful and sourced me a replacement ECU, which made no difference. I then swapped the coil and the power unit - that made no difference either.

I've rechecked all the earths (again) - everything is continuous and grounded. As a last resort, I started to re-check sensors. TPS is fine, WTS is fine. However, despite having 12V at the input connector (white wire - terminal B), my AFM does not deliver an 'in range' signal output on terminal D - black wire (which connects to pin A6 on the ECU). It should be 0.2-0.8V - mine is 0.01V.

Question - can a faulty AFM stop the ECU sending an ignition output signal to the power unit? I still have 0V at cranking on pin C6 (should be 1-3V) and consequently no spark.

PS: the CAS is working fine and delivering a signal to the ECU (pins B1 and B10).

Cheers Adrian

It sure can... I actually broke the wire from my ecm one time while doing some other maintenance and it took my a while to figure out why the car wouldn't start.. YOu can try unplugging the AFM completely and try starting the car, sometimes they'll run with out the afm (barely) but sometimes in the case of the ECU, no signal is better than a bad signal.

Thanks mate - I'll give that a go when I get home tonight.

Thread revival...what about a bad ignition switch? Can a bad ignition switch not send a proper signal to the ECM to allow the injectors to pulse on cranking?
