Remote Start - Engine Dies

My 2008 JKU Sahara with factory remote start is working, but the engine dies soon after starting - the parking lights go out - the alarm light on the dash blinks.

Everything seems fine, but the check engine light has been one for a long time (O2 sensor, I'm told).

Would the check engine light cause the remote start to shut everything down? Winter's coming - that's when I use it.

Yes many engine performance codes will allow it to start then die. With a door ajar it will not start at all.

What is your definition of soon? It will shut off after so many minutes and I believe it is ten minutes.

The CEL will cause it to start and then shut off in about 5 seconds.

Low fuel (fuel light on) also replicates the exact symptoms you describe which is normal for the system.

The five second seems about right.

I had my check engine light looked at (at an auto parts store - if that's worthwhile?), and they said it was an o2 sensor. The light HAD BEEN sporadic - I've been hoping for a time when the check engine light wasn't lit to test the theory, but it hasn't been happening.

I guess I may have to have the damn sensor fixed to find out.

Thanks for the answers!

Just called dealer. There are four 02 sensors, and any one can cause the remote start to fail. I guess it will need to go in.

Thanks to all!

If the check engine light is glowing, the remote start will not function. Well, it does, it does exactly as you say. Need to clear it and the remote start will function properly

What was the code? That should tell you which O2 to replace. Bank 1 or bank 2 sensor 1 or sensor 2.
