06 is250 electrical issues.
so i did my research and cannot for my life find the issue. I walked up to my car and the door unlocked fine. I got in it and slightly had my foot on the brake, i didnt mean too, and pressed my push to start button once to turn my power on than all of the sudden all my power cut off. My doors wont lock or unlock. hazards dont even work. i tried jumping it, didnt do a thing. i checked all my fuses and theyre good. Checked my main fuse and its good. My battery is good. I just changed my key battery. im thinking im going to have to pull the ecu and check it. if i cant find the issue ill have to tow it to a shop. any one have any idea of what could be happening? should i try to try to reset my ecu?

Im about 90% sure its the battery because I had this happen on 2 vehicles and 2 bikes before. Sometimes batteries read the proper voltage but dont have enough amps to start the vehicle let alone the electronics. I've gotten to the point where I am ripping apart the entire car trying to figure it out when trying a new battery worked in an instance. Take your battery out and try it in another car or take another cars battery and try it in yours. There you would find your culprit.
What my last car would do is start all the electronics but the moment i attempted to start it, it would cut out. Unplug the battery and it would do the same thing over and over.
