2022 Viper will not start when cold, but fuel pump works??

[Snorover]

MY viper will start when I heat it up, starts with no problem. Can't count on that in cold weather. I switched fuel pump relay with no change.
Could it be the ISC relay??

It's suggested to change out both the fuel pump and ISC relays for the sealed ones. I have never had an issue starting in down to -23F weather with the Roc Toys ones.

I have a 2020 Viper and have always had an issue with it starting cold. Not weather wise, but just in general. I was told it's just how the sled starts. On a side question, Would a straightline header and exhaust help? I noticed that if you crack the throttle the sled turns over faster. I was wondering if with the less exhaust pressure help? And I had already had the sled checked for current flash. Sled came with the updated ECU flash.

My viper never started well in the cold as well,I'd stick a hair dryer under the hood for half hour.
