Big3 upgrade GONE WRONG! 2008

Hi guys, I finished installing everything.

0gauge - fr positive alternator to battery pos side
0gauge - fr neg engine block to battery neg side
0gauge - fr neg battery to sidewall.

So after I hooked up all these, try to start the truck no click no nothing and all dash lights up. Took key out and close the door, then I pressed the unlock remote fob IT CRANKS WITH IT!!!!! Wtf!!!
PLEASE NEED HELP!...

 

Welcome

 

I thought the 2nd one was supposed to be engine to frame. I guess it could go to battery but never seen it done that way.

 

Sorry guys I just got on the board, fr East Coast. Just never got a chance to join in...but thank you.

 

So if I am following this, you seem to have created a remote starter? Wow... I am inept at best mechanically, but would probably disconnect the battery and call a mobile mechanic. Good luck and welcome!

 

Yeah, but the thing is, I put back the way it was and it STILL doing the same thing. Unbelievable...
And thnx brother...

 

Did you remove the stock cables? I think it s better to leave them, and just make the same connections as original cables

 

No, I did not remove them. All I did was added.

 

Update on my truck. Left it overnight, the next day I unlocked it then NO start, it was a good sign! Went inside try to start it then STARTED!! but on a low idle about 4krpm.
Started messing with the maf sensor, unplugged it then plugged it back it got worst. So I will try to spray some maf sensor cleaner, hopefully that'll do it...
I'll let you guys know...

 

Strange. If you can start engine I would scan obe2 and see if it throws any codes.

 

Yes it did threw a code but didn't get a chance. I went on YouTube check on maf and that's how the guy did it with a spray cleaner so crossing my fingers...

 

I would suspect that it would be the maf sensor cuz what I did was, when I took the airfilter box out, to get to the ground wire, I had the maf sensor out in da open for a while and pollen was just everywhere but who knows will see....

 

This one is weird.... Gremlins maybe?

any lights, chimes, horn, cluster, radio?

maybe try this

1. Disconnect the positive terminal from the battery. Wait for several minutes and reconnect
2. You might have drop a secondary wire from any of the bolt / nuts when you lossen them
3. Check fuses
4. Reinstall old wires

 

Not 100% sure but you should prob go to the frame, not the sidewall

 

UPDATE: well guys, everything is back to normal with the Big 3/4 upgrade!!!
Sprayed the mafsensor and put dielectric on the alternator positive side. Drove on the highway, got back at my house, set it in park, running in between 700 to 800rpm. RUNNING SMOOTHLY!!!

 

that was scary!
