Pontiac Torrent nightmare

[mwells]

My torrent was left on acc and battery went dead. replaced battery with new one that checks out. Will not start or even turn over.
First i couldnt get key out but can now but pushing pin in steering colume.
second, nothing works fob, lights, locks, wiper (high only), no brake lights and will not turn over.
third, will not turn over in park or in neutral.
Have checked all fuse in both boxes.
Im at a loss, any help would be greatly appreciated

How did you determine the new battery is good and you are sure the battery cables are correctly attached and are tight?

 

[mwells]

took back to auto parts store and had them check out

trace the positive battery cable in order to find a melted/broken wire. What year is the vehicle?

 

[mwells]

Will do. 2007. have some lights on dash panel and radio comes on if that makes a difference

 

[mwells]

red wires from battery to fuse box and the starter look good

You have relays in the engine compartment box. One of them is the main ignition relay. If it is the same as the AC relay or light relay, switch them to see if it will start. Look on page 435 of the owners manual.

switched relays and still nothing.

 

[melsg5]

can you use a voltmeter and check some of the fuses for 12+ volts in the engine compartment fuse box for some of the lighting systems that should have power when the key is in the run position. can you see the underside of the engine compartment fuse box to see if anything looks melted/corroded?

back from the dealer. BCM had gone bad. $530.00 repair.
