Double check your work, make sure you didn't bump any connections? Make sure batteries are fully charged and connections all good. To see if starter motor will crank the engine, you can pull starter relay, use jumper on switch side of relay, left side in the picture, between terminal 30 and 87 cavities. As you can see terminal 30 is hot all the time and fuse protected. The starter motor should crank the engine? Using the jumper will bypass the tranny range sensor. If you try that, make sure tranny is in park or neutral and parking brake is set. I won't be back online till tomorrow, good luck.
