My dad recently picked up his 2004 Infiniti G35 with over 200K on it after it had been in the body shop for about 2 weeks. It was very low on gas but made it to where he was going. When he tried to start it again, it wouldn’t start and we added fresh gas from a new fuel canister. It started up and then stalled, and that’s how it’s been operating ever since. Crank it up and it stalls unless you immediately pump the gas pedal. Once it runs, it runs fine. Thanks for any help with this.
