I just got in my 04 blazer today and tried to start it and it struggled at first and when It did start it needed 1,000 rpms to stay running. Each time it died I try again and the same issue happened. I waited a few minutes and then it started up fine and stayed running. I did notice a continuous clicking noise coming from the dash when starting. Not sure if that has anything to do with it.

So far it's seem fine but worried this might become a huge problem in the future. If any of you guys have had similar problems before and we're able to solve it your input will be greatly appreciated.

 

Check fuel pressure. Possible bad pump.
