Car won't start after install - need help - 07 sierra

[garrit]

So I have an 07 GMC Sierra. I installed an amp and subwoofer last night, started up my truck and listened to a couple songs and enjoyed my new subwoofer. This morning I go to start my truck, and all the interior, headlights, and dash lights come on; but when I turn the key it doesn't even click or attempt to start. My radio and amp doesnt turn on either now. So my half-knowledge is telling me that I blew a fuse on the wire that I hooked up my remote turn on wire to, but I've been using this same wire to turn on my head unit. A kinda of pink orange wire in the ignition bundle in the steering column. I spliced into it and hooked both the amp and head unit directly to that wire.(not sure if that was a good idea). Any ideas on what might've went wrong or what fuses to check? Or atleast how to get my truck to start so I can get to work.

Edit: yes, I tried to jump it and the battery was reading 14 volts.

Why would you splice into the ignition wire if you have an aftermarket radio that has a remote wire in the harness?

lol...I wondered the same thing.

Next question..

I mean my remote turn on wire that I ran to the radio is connected to the same wire in ignition bundle. I

Figured splicing into that same wire would have to same

Effect. But now I realize that it would have been better to hook it up to the radio remote turn on wire because it has a fuse. I buying a PAC asap tho.

chip system ACTYIVATING. Check the starter. Is the starter getting power check voltage at starter. (believe there is still a fusable link in gm cars at the starter.)

Battery connections are good.

Hopefully not, I guess that's what I get for going the cheap route and not getting a PAC.

yes always worth the harness. How did you tap into ignition make sure all connections are good. check fuses.

 

[garrit]

I'll have to check start once I get home. Uber everywhere rn.

 

[garrit]

Going to pull fuses later. Then just say forget the amp and sub till

I get the pac. #1 priority rn is getting my truck started. Tapped into a wire in ignition bundle.

 

[garrit]

How would I **** up my computer? Hopefully, it's just a fuse purchasing a pac

Asap.

All the wires in the ignition bundle are low current

If you blew the output for ignition sense it will not tell the truck to start

Disconnect the wires you tapped to get power and try to just start the truck

You can get switched wires else where just not there

You don't need the Pac if you are already running an ignition wire

You just need to tap the right wire
