Newby here so plz bare with me.
I have a 2009 Nissan Maxima with the V6. It cranks but wont start. I'm getting spark. It will start on starting fluid. Using a noid light, I do not get a pulse at the injectors. With a MK808 scanner, I was checking live data. The intake cams both said about 39°CA, but the exhaust cams had different readings. Bank 1 read 63.5°CA and Bank 2 read -20°CA. That's 83.5° difference. Is that correct? Or should they read the same? I tried shuffling the sensors around but it made no difference. I'm assuming that means that the sensors are good.

What else controls the injector pulse besides the cam sensors?

Any help would be much appreciated.
Thx.
