Hard Starting F-250 Superduty
 

Recently I changed both batteries in my 2006 F-250 (68k miles) since that time the truck has been very hard to start. This was not the case before the batteries were changed. AT WITS END.

6.0l Diesel Recently rebuilt by Fomoco Complete

Also new fuel filters 5k miles early

feel free to email me with any ideas, cause this started 5 minutes after both of the batteries were changed
