hard starting, even when plugged in
Went out today and started the truck after its been plugged in all day. It was 7f and took about 5 seconds to start. If its been plugged all day then shouldnt it fire right up on the first revolution? When i changed the fuel filter a while back, it was full to the top, so i dont think that air intrusion is the problem. I'm leaning towards it being the starter. It looks like it has the original starter. I plan to test the battery cables with an ohm meter so i can eliminate those from the equation. Batteries are in good shape.

is it spinning over fast enough?i would suspect weak batteries weak starter or bad connections.go through and clean all the battery grounds and connections and then make sure the connections on the starter are good and also make sure the solenoid on the starter is tight i have a problem with mine coming loose from time to time.it is heldonto the starter with 2 phillips screws

man that thing starts hard.i would load test the batteries again.and if it is still starting hard like that put a return line kit on it.best thing to do now would be get new 4 new cable connectors and clean all your grounds mainly the big one on the pass. side of the block.

its not spinning over as good as it should.and its not firing soon enough of course.
this is what mine sounded like before i began fixing.(though it took longer to start.)
how do your cables look? my 93's where pretty corroded.do you see burnt marks on the starter cable connected to the pass side bat? if so,if you cut the wire open,i bet you will see green corrosion.this is no good at all and kills your cranking power.
if you need to replace the cables,try and spring for the extra 3/0 AWG wire,at least for the bat/starter line.
this makes a big diff.
be sure to take off the grounds at least,and shine up the block where it bolts to it with sand paper.make it look like a mirror almost lol.it matters.
but be sure to inspect those cables and replace them before you spend the $ on a new starter.(that would be dragging due to old cables too,and make it wear out sooner.)
when you get it right,that should spin over almost twice that speed,if not twice.(least with 3/0 throughout i know it does.)
edit:yeah,after listening to it again,im sure mine spins over at least twice this speed.
also,you didn't state if you tested your GP's either.

you know i got to thinking,you only have about a 7 sec WTS light there too.this is not good.

Daves very,very right about "On the new style system, glow plug resistance is critical."
i still had slight problems after changing the dead ones via test light method.i changed the others(was cheaper than buying a meter that could test accurately this low) and oh yes,it was worth it,even though they lite up via test light.

from the video it looks like he didnt cycle the plugs long enough and the engine isnt spinning over fast enough. the wts light should stay on for at least 10 to 15 sec on a cold motor. with my truck my gp system works great but you cant go by the wts light because the light goes off way before the plugs are hot. i ether go by watching the volt gauge jump or wait for the solenoid to click. also check the plug on the pas side fender that feeds juice to the controler, its bad about corroding and melting the plug. it building alot of resistance and causing a hard start efect because the gp are not receiving the right amount of juice to cycle the plugs. if you had the batteries tested then i would look for bad and corroded conections on the battery. dont forget to check the conection on the starter also. dont know how old the starter is but as time goes on the starters have a tendency to go bad, its do to long cranking times and bad and dirty connections. i wouls look at batteries first (cold kills batteries lol), then onto cables and connections being tight and clean, then onto starter. just remember these engines rely on gp's especially in cold weather.
