Car wouldn't start after doing pulls

0025_SS · 02-08-2021, 06:55 PM

I have a 2016 Camaro 2SS A8 with 37k miles.
List of mods are as follows:
Supercharged Magnuson TVS2300
TSP Headers 1 7/8 no cats, DEI heat wrapped
K&N Air Intake
LT4 Fuel Pumps, HPFP and LPFP
Snow Performance Methanol Injection Kit
ATI Super Dampner Crank Pulley
DSX 230mm Underdrive Pulley for the Blower
Borla Atak Axle Back
BMR Lowering Springs
Car makes around 600 wheel horses on 14lbs of boost and around 617 ft-lbs of torque.

A week before my pulls I arced the battery trying to jump start it using reverse polarity as a mistake when attaching the jumper wires. It was a quick touch and go when that happened. We then found out the starter has failed. Replaced it and she starts again.

Then, during the pulls my car suddenly won't throttle anymore but instead slowly the RPMs go down. I stopped near an exit to figure out what happened. My temperatures were higher than normal, I had no leaks, there I thought I overheated. The only check engine light I got was from a Cam Positioning Sensor and 02 Sensors which I get sometime an issue happens with the car. After a few attempts on starting, car turned over and died the same minute with a different idle. Then started again a couple more times.

I now got my car at the shop that built it, they replaced the positive terminal fuse, and charged the battery. Still we got nothing. They are about to replace the starter again and we will see if that is our problem.

If not, can anyone help me please? I am very frustrated at this time. The shop is recommending me to bring it to the dealer if the starter is not the issue.

I am sorry but, how do you mess that up?!?!?!?!?!?!?!

I don't know if it was too much boost, overheating, electrical or mechanical.

I mean mixing up the

Red/Black

+/-

That is like elementary stuff in car terms.

I was tired and stressed from work. Then the red and green anti-corrosion washers were in the wrong places.

bummer, as for your issue, electrical gremlins can be hard to find. Maybe something go zapped.

I will keep digging to find out what it is.

If it is cranking but not starting it's not the starter.

Sounds like the polarity got reversed on something permanently. Hope nothing got fried and its simple. A friend did that on his fox body years ago and had to change pcm, harness and a bunch of relays.

Did it fix his issue?

His car was good after that.

Around 6 months now.

While not relevant with regards to your current issue, you should be making well over 600whp if you're running at 14psi
