At a loss need help

[Nathanv]

I need help with my 2011 ram 1500 I just did cam and lifter replacement and got everything done went to start it and was having weird electrical issues as shown in vid I will put on, I jumped the starter at the relay because I couldn’t crank it over and it cranked, fixed two grounds and it randomly started working the electrical issues I wa having was crazy the relays were clicking on and off and everything was going nuts. It all stoppped randomly after doing the motor multiple times. But when it did run it was in limp mode with a check engine light, I had a high bank code for an intake runner position selonoid, I pulled the intake looked at the selonoid and it was like spinnning and it wasn’t doing anything at all. I replaced it with the doorman repair kit plugged it in to the original harness because I diddnt think there was a need to wire in the new one as my wiring looked fine, and I plugged it in all this weird electrical crap returned. I have it at the ram dealer and they can not figure it out either and say the selonoid is spinning weird and doing weird things and they are baffled at what’s wrong.i should also say my obd reader can’t connect to any modules, it says 0 n/a Or something and it won’t connect to anything this wasn’t happening before the sensor replacement now after replacing the sensor thing it’s not even connecting to computers
Vid of electrical crap.

Scan it for codes, or a lack of communications. Pay specific attention to anything that says "lost communication" or similar. Print out the info, as that will tell you where to start searching.

Grab a flashlight and scour the engine bay looking for damaged wires and connectors.

Look at everything, not just the stuff you disconnected doing the job, but anything that could have got broken, pulled, pinched or that you could have leaned on, layed on or dropped something on.

Look from the engine well, under the truck, inside and under the dash. Chances are, there is a Canbus wire or connector damaged or disconnected.

In many cases, when a module drops off the network, the peripherals the module controls will start going *******. The BCM in particular will cause wipers to turn on/off, horn to start blasting, lights to start flashing randomly.

I think @Ken226 ^^^^^^^ nailed it. Could be just one shorted wire, or a loose connector. Gotta look at EVERYTHING you touched with a magnifying glass.

It’s currently at a dealership getting worked on I threw in the towel and they can’t figure it either. They said they are looking at modules and stuff and I’ve told them I think it’s the wiring from the selonoid I had a code for going to the ecm.

As stated above it most likely is a bad wire or loose connector somewhere. If you already found a few grounds loose or missing there is a good chance there is something else going on. On a CAN Bus vehicle (the basic communication format of the ECM) everything is tied together and one bad module, or a wire going to one module, can disrupt the communication (commands) the ECM is sending to all of the modules.

If it would not crank over to start with, and it was fine before , you forgot to plug something in or you smashed a harness some when putting the motor together would be my take on it.
Pulled wiring apart in a connector? Bent pins?
Some of your post is a hard read .

Pull your connections apart and look for bent pins.
