ok so i disconnected all the sensors and pluged them in one by one, cranking after each...... nothing. so after all were reconnected i pulled all the ECU wires off and there was no difference in cranking sound/dash stuff so im gonna get a new one. if that doesnt work im done.

I wouldn't go that far yet new computers are $$ and I ment for you to leave the key on and unplug the sensors one by one I'm sorry if I was unclear in a previous post

X2 fuel and volts are sensors that are tied together with a 5 volt reference to so the PCM can keep check on everything. Turn your ignition on and one at a time start unplugging sensors when you unplug one look at the gauges if your fuel comes back up to normal replace that sensor if not plug it back in and try another. ( if the sensor got "bumped" lmao in this case and internally shorted itself to ground the asd will not be aloud to energize to run the coil or injectors. Hope this helps
