Your RPMs while cranking should be 150-300 RPMs. You can have both the batteries and the starter load tested at your local auto parts store. If they aren't tip-top, it makes for hard starting.
87 6.9 Hard starting
For the past few days my truck [87 f250] has been giving me a fit in the morning.I even ran the batt.s down one time!I had the intake gaskets replaced a while back,after that for some reason the wait to start light quit working.What i've been doing is cycling the plugs by waitng for the clicking sound under the hood[I do this twice]she usually fires up!After i get it going it'll be fine all day.I have noticed that lately when i start the truck almost every time it stumbles a little.
I have checked the fuel lines and yesterday i replaced the rubber
hoses between the injectors.They were in bad shape,but still have the problem.It seems like its turning over good,i had the batt.s checked and they are fine.
Thanks in advance for any help!!
