You are correct. Has injector in throttle assembly.
Dash and ignition switch work fine. When i disconnect certain items such as tps or maf or an ignition coil I was able to get a code to pop up for that item. The. I'd clear it out. Attempt to start and may hear a sputter. But no codes. On occasion it will start. But eventually die. Not sure if it dies due to warm up or not. Would think it'd throw a code for crank sensor but you present a good point.

Question: what's the switch module suppose to do? Control ignition? Part number 22710 fu460
