X5 3.0 would start then die immediately...after 4th/5th time it started..now have SES

[khelms_98]

My X5 3.0 sat for a little over a week, during that time I replaced the final stage resistor, and when I got in it this morning, it would crank and fire but then immediately die; it did this a few times before finally starting, this time it stayed running. After it started the idle was a little rough but within seconds it smoothed out and ran fine, but now I have the SES light. The battery is okay I assume because it actually turned over and started, but it just wouldn't stay running initially. Could this be the result of not starting it in over a week? Any thoughts? Thanks
