Exclamation something weird i cant find an answer to!vid!

WATCH VIDEO FIRST

Ok i cannot seem to find ANY information on this problem im having.The previous owner told me it did this i thought ok whatever its probably just a loose ground i just want an ls1 he thought the same also claimed to have brought it somewhere and they told him it was but didnt find it and fix it. I have checked every ground i can find and there all good (can someone show me a listing of all ground points to make sure i got em all). It happens randomly and i can hear a clicking coming from one of the two fuse boxes under the hood when it does it. i really have no idea what to do i need to get it taken care of ASAP i am supposed to be trading the car very soon.

All lights coming on in your video are controlled by the PCM. The PCM grounds to the back of the LH cylinder head. I would check that first. Also check to make sure the battery connections are clean and tight. Check the cable from the battery to the frame and well as the battery to the block. Check these and see if you find anything. Whats the condition of the battery and charging system?

I've gotten that clicking sound from the dash when my battery connections weren't fully tight, but never anything with all the stuff flashing on the dash.

i had that happen once on the first startup after i had my battery disconnected for about a week... i was like wtf!!... i jiggled the batery cables to make sure they were tight and saw a blue/green powder come out of the positive cable boot... so i ended up having alot of corrosion built up inside that boot and that's what caused all the dash lights to flicker on that initial startup... i cleaned all that crap out of the boot and haven't had a problem since

I had the same problem but the car wouldn't start at all. Ended up replacing battery terminal bolts and took a wire bush to the terminals on the wires.

Maybe the connections on the pcm? Try dielectric grease on the connectors? Could it be a bad connection on your gauge cluster? (kinda doubt it but maybe) Something somewhere is gotta be loose

yeah that's a good idea, overtightening the 2 bolts that hold the connectors to the pcm can cause a bad connection

Mine was doing something similar. It ended up being the bolt that holds the negative wire to the terminal was stripped from corrosion, and it wasn't making solid contact. Bought a new set of bolts from Advance and solved the problem.

Just for anyone anyone else who might have this similar problem...it was my fuel pump!?!
I knew mine was bad but didnt think a fuel pump could cause problems like i was having,bought the racetronix kit and it fixed everything...well besides my headlights not going off but thats a whole different issue.
