Truck is starting harder

Recently my truck is turning over slower. It has been anywhere from 40 to 70 when this has occurred. It doesn't seem to matter if it has been sitting for a day or two or short time (it may be a little worse after sitting for a day or two). It has been puffing a little more white smoke when it starts.

My batteries read 12.29 volts after sitting for a day. and 12.9 volts after running for a couple minutes. I separated the batteries and they both stayed around 12.8 (truck off).

Does the voltage sound okay?

Is this a sign of the starter getting weak?

Thank you for any help.

I replaced the glow plugs 6 months ago and put on a Stancor relay

Re: Truck is starting harder

Sounding like starter. Min was similar if it sat for anything over a hour or 2 it got slower to start... The Starter was the last thing i changed... Alternator, batteries and finally did the starter. :)

Re: Truck is starting harder

If it's cranking over slowly, I would put a new starter in it. Makes a world of difference. I went through the same thing this last summer..

That voltage while running should be a little more I would think after the glow plugs and everything turn off.

Re: Truck is starting harder

Have your batteries tested individually at the auto parts store and then if they pass go with a starter

Re: Truck is starting harder

Indeed, voltage while running should be higher, but don't bother checking until after you know the glow plugs have cycled off.
