[Oh Haha]

My work rig wouldn't start this am. The same thing happened last week one day as well. After a jumpstart from our mobile tech it ran fine all day.

We plug the block heaters in overnight and mine truck was plugged in from about 3pm Friday until 6:00am today. The truck is an International with a Cat engine.

I jumped into another rig and left but had called the repair service so I didn't get to talk to him. When he arrived, he jumped started the rig and it fired right up.

One of the guys I work with thinks that the reason it wouldn't start is that the block heater power was not continuous over the w/e. Ours are on timers.

The truck I drove had sat for over a week without being plugged in at all and it fired right up. It's a 2009 GMC with a Duramax.)

Nothing int he truck was left on over the weekend that would have drained the batteries.

I'm not up on diesel engines but it seems dead batteries pretty much have the same symptoms no matter the type of engine.

Anyone have ideas to share?
