First time posting but I've been using these forums for years. A recent issue has me stumped so thought I would post symptoms. My O8 2.4 Panel LS will start right up and run for ~3 minutes before shutting down. It will not give me any error codes and will only start back up for a few seconds. I've tried replacing solenoids. and sensors but what it really needs is any oil change having 225k miles. I can't drive the car to have it serviced as it will shutdown enroute. If I disconnect the negative ground and wait before trying to start it up again, the same thing occurs with it running fine for ~3 minutes then shuts down. No codes are ever given to trace down. Any thoughts or suggestions is greatly appreciated.

 

What solenoids and sensors? Why would you do that?
Has the ignition recall been done?
My wild guess is either the fuel pump relay or the fuel pump.

 

Are you using the key, or remote start?

 

1. LS models only came with the 2.2 engine.
2. As Donbrew asked, which ones and why.
3. Sounds like it's way over due for an oil change. Maybe the oil level is so low that the engine is losing oil pressure and shutting down.
4. You are rebooting the computers and that clears any trouble codes.
5. May be because of you clearing codes from disconnecting the battery cable.

 

Can you hear the fuel pump?

 

The OP came back later but didn't provide any details or answers. Guess they weren't really looking for help.
I'm out.

 

Sorry for the delayed response, as a distributor I own a fleet of Panel trucks. This truck is an 08 2.4 LT. Yesterday, I reset the system on a battery disconnect and ran the car at idle for ~8 minutes before it shutdown. However, this time upon going to restart there is a check engine light. I'll get it read and post back those results this week. Thanks for everyone's help and replies.

 

Potted palms in the corner.

 

Seems a bad ground or failing fuel pump

 

Read the single code today and stated it as a P0106 MAP Sensor. I'll change it out and see how she performs. Keep you posted, Thanks!
