Default Re: No crank after new keys

I had zero issues before re installing the skreem, antenna ring and ecu. I put the battery terminals on with the key mistakenly in the on position. I was worried I might have fried the ecu so I tried to connect a code reader to my obd port and the reader now cannot connect to the ecu. I decided to replace the crank and camshaft sensors on a whim...no luck. I checked the rcm solder connections and fuses all good. I checked to see if the rcm was functioning with the key on. Everything functions when I manually close the relays. The 2 relays close when the key is in the start position (verified while the wife tried to start it). I ordered a new rcm incase my current one is somehow faulty.

Any ideas on where I should proceed next? I contacted Rob at NEEDSWINGS to see if he has seen this before. Any help is appreciated!
Hi Jonathan,
I don't think you mentioned if your limited was an automatic or a manual. If it's an automatic, is the gear position indicator in the instrument cluster showing the right gear? (Should be P for park) or a black square? Also, just to be clear, when you measure the voltage across a fuse, that means put the red probe on the contact, and the black probe on a ground point like the negative terminal of the battery. Then move the red probe to the next contact point on the fuse. You should read battery voltage (~12V) on each contact. If you try to read the voltage drop across the fuse, you'll read a very small voltage assuming the fuse is good.
Good Luck,
-Jerry
