Great video..This saved my huge headache figuring out my misfire...THANKS!
This video saved my life!! My marriage, my money and my sanity. Ls3 was backfiring so loud all the neighbors came out.
I’m in the same process right now my wife kids neighbors are pissed off
I remember making this mistake and didn’t get to complete my dyno session. I had flipped the coil harness some how during my LSA blower install and had it 7,5,3,1. Long story short I figured it out after towing it back home. I just wish my tuner knew this and we probably would have identified the problem right away.
Mr. Hillock,
Thanks for this video! I recently installed a Chevy Performance Stand Alone Wiring harness for the LS3/480 and could start my engine, just backfires and sputtering! After your video, I turned the coils terminal 180° and the engine started immediately without a hiccup! Yes, the wiring harness was inverted! Thanks again.
Glad to hear the video got you up and going! Thank you!
Thank u very much
I'm new to the LS game (and very late, lol!), so this is great info! Much appreciated!
I'm proud that the best harnesses are made right here close to home.
Nah, you’re not late, no better time than the present to get started!

Will do...👍🏻
Hey bye any chance any type of coil harness thay will work with holley bracketless cover
Perfect video Thankyou
Awesome video!
Thank you!
Did this exact same thing haven’t fired it yet but I knew I had to double check
Learning as I go, but this video helped. I bought after market coil wiring, and I had the passenger side reversed. I could never get it to start right up even with a base tune. It has always taken multiple cranks and lots of back firing.
Thank you.
Glad we could help!!
@@bpautomotivellc great video I’m currently running Jegs 40164 GM LS Ignition Coil 1999-2007 5.3ls would the Set 8 GM OEM Delco 12611424Ignition Coils LS3 LSA D510C 12570616 work for my application and would I need to retune 5.3 ls turbo build car has already been tuned
The electrical components like ignition coils and ignition coil harnesses is what makes the vehicle run. They’re not like older carbureted vehicles. They’re specifically designed to run the most efficiently on OEM parts. When you start putting in cheap or even expensive aftermarket parts, then you change the way the computer reads that part. The OEM replacement part is designed specifically for the factory tune of the vehicle. Aftermarket parts are not, because they’re not the manufacturer who knows how the factory tune is. If you have the vehicle tuned away from the factory tune then it’s a different story, because it can be tuned to the aftermarket parts. But aftermarket parts on the factory tune is a no go. Replace the sensors/ignition parts or harnesses with OEM parts.
Please help just got a new set for my 2005 gmc serria and the wires are different colors and I can’t tell which go where one has pink in it one has red and so on
Great video
Any idea which color is grounds
I just found the cyl #4 have power but still no spark
Had switch ; coil ,cable or wire, spark plug. And still no spark
Tester light up in 4 prongs,
Do I need a new harness???
Thanks
That’s not enough info to say for sure! The ground is black and is in cavity A!
Hi mate, my LS2 coil connectors are all the same colour. Red, purple, grey, black.?
Sounds like you have aftermarket reproduction harnesses that did not follow GM Color Codes.
Do you sell these coil sub harness?
couldn't;'t
How come my coils keep going bad ? It’s a 5.3 2001 they keep burning out
Is it the same coil that is failing or random ones are failing?
@@bpautomotivellc I’ve put 3 sets already it gives me a p0300 and it lacks power I put in a new set works good for a day and then it goes right back to no power hesitates I put new wires also! The only thing I haven’t change are the plugs! But there is spark coming out from each coil which means they are working but maybe not 100%
@@520racing6 Have you checked to make sure your injectors are clear? Also, does this engine have an aftermarket cam?
Yes it has an aftermarket cam
@@520racing6 That code needs to deleted out on a cammed application.
