I have an 07 Tahoe LT, has 180k miles and has had trouble starting for a while. The thing is though if I go to start it right in the morning or after not driving it for a while (2-3 hours) itâ€™ll start right up, but if I go to a gas station and fill up and try to start it, it wonâ€™t go. I think itâ€™s a security thing because itâ€™ll crank just fine but it doesnâ€™t seem like itâ€™s getting fuel. The key for the ignition is slightly bent so Iâ€™m wondering if that might be the reason. Also itâ€™ll start if you drain the battery then jump it.
