2005 g35 coupe auto. I purchased the car not running properly. Since I got it home I've done the following.
Codes:p1122 and 1126
Ran the diagnostics steps to find out what was wrong. First attempt I found a bad IPDM.
Went for a used ipdm from pull a part, Replaced ipdm.
Ran diagnostic steps again but now I'm not getting any signal from pin 3 on ECM.
Which should ign on batt volts.
I was getting this previously, I put old ipdm back in and still not voltage out of pin 3. Checked fuses, checked continuity from ECM to ipdm just not voltage.
Any advice??
