remote start with low fuel

cc rider · Jan 26, 2015

ok. It's 16 degrees earlier today. I hit the start on uconnect, get outside and its cold. I had forgotten to get gas. Later I used the remote to start it and it starts but shuts right off. Of course it occurs to me that I'm still low on fuel.
Now, I now the remote start doesn't work when it's low on fuel and I procrastinated getting gas. But can someone explain why the hell the truck starts just to shut off .these guys are actual engineers?

I seem to run into this problem after my wife drives the truck and is too lazy to fill it up. The first time I thought something was wrong with remote start. I agree though if it's low on fuel why even bother starting to just turn off immediately.

Its got to start to boot the computer so it can read the fuel gauge and make the shut down decision.

its a safety feature so you dont run out of gas by using the remote start

That's a good thing then. Since my wife loves to leave the truck with 1/4 tank for me

Lesson... Dont let Wifey drive your Ram. mine has driven my ram once in the year we have owned it.

I would have rather taken the risk. I know exactly where I was . I was only 1/2 mile from a gas station. My light just went on so.....I would have had plenty of fuel to warm the truck up and then some, but it shuts off.

Then the computer should boot without starting it to do its "checks" Just venting

your truck doesnt know that your that close.

its the engineers way of putting a fail safe in so you dont run it out of gas and blame it on dodge when you are stranded

Well.....everybody keeps saying how smart these trucks are. Run out of fuel and be stranded or freeze to death......whats the difference?

Just go put some gas in it. Or walk outside and put your key in and start it. Problem solved.

I did. Back to 32 gallons

I would disagree with this. On the basis that if your alarm was tripped the truck won't start. Therefore it at least checks in with the BCM prior to start. It also has to do a boot on the ECU which would in turn query the TCU about park status prior to activating the starter, fuel injection, etc. It definitely primes the fuel pump prior to kicking over, so you know the electronics are hot.

I would say some engineer should have called that subroutine a few lines of code earlier...

The other thing is, hindsight is 20/20, but they could have done an optional flash update on older tucks if you happened to be in for service/maintenance, and the newer trucks could have been sent out with it from the factory.

Or you could keep gas in it and get on with your life...

Exactly. Keep it fueled up and you'll never have to worry about it.

I never let my truck go below 1/4 tank, so I am not sure why you are pointing that at me...?

I was just offering input to the discussion regarding the truck's startup sequence. I agree that it is a relatively insignificant topic, but that doesn't mean people can't talk about it, and share information.

It is possible it starts and stops to let you know that it is operational and you are within range, but there is a problem that is preventing it from operating. If you tried the remote start and nothing happened, you might keep trying or you would want to check and see if the truck could start at all.

Good point. That isn't something that had crossed my mind!

I think your over thinking a issue that really is just user error. :favorites13:
