Default a Ground problem..??

Aloha guys.. So was off for an adventure this afternoon in the truck, Was going to hit up a nice 4x4 road with some mud..
But I hop in and turn the key.. and nothing happens no Wait to start, no idiot lights, No clicks..

So climb under the truck and notice It looks like my downpipe coming off and banging my valve cover <-- (previous problem) might have busted this ground cable
Passenger side, left corner theres a bolt with a bullet type connector thing, Looks like where the cable went.

Could this cause such issues? I don't know much about electrical stuffs, But I sure was

Mahaloz

The PCM has a couple grounds but most notably the one on the driver's side fender near the hinge spring.

I'd try turning on the key, turning it off, then turning it on again within about 2 seconds. That will give us some ideas.

ook! so.. grounds are good I think..

had a check engine light finally, this is just as I turn the key.. I get the Wait to start every thing else
But a check engine light too
so Im hearing ticking sounds from the underhood fuse box.. and its Relay 2 which is the IDM relay..

unplug that every thing is fine, no CEL no weird door ding sounds, but didn't try to crank it over..

What could this mean..? a bad IDM? Me and my buddy did the IDM mod (his soldering skills) could something have gone wrong..? should I pop the stock IDM back in..?

Seems like some gremlins are playing tricks wid me...

Are the battery terminals clean and tight? Batterys fully charged?
