my 90 f 250 has a starting issue..
when i turn the key the cranking starts out real slow then gradually gets faster.. after a few times of cranking and letting the starter cool, and cranking again it gets enuff speed to fire..
any ideas?
i was thinkinng it might be the starter? but im not sure..

Ensure it's in Park or Neutral
Set Parking brake
Chock wheels
Have some one turn the key to start while you feel cables and connections, bad connections get hot.
If you want to prevent it from starting for testing, disconnect the FSS on the Injection pump, Disconnect the forward most (to front of truck) wire on the Injection pump.
The most common connection failure point is the positive battery terminal on the right (US passenger) side.
If the cable insulation is bulging at the connections it is corroded.

x2 on battery cable being corroded. these things can get eaten from the inside out. quick way to find out is to run a jumper cable from the battery on the passenger side down to the starter stud. then try cranking again. if it spins faster the first time then you know its a cable issue. you might wanna hook the negitive clamp to the battery and then to the block. could also be bad ground cables causing weak connection.

theres the fat post that the battery hooks to, then theres a smaller post that a thin gauge wire slips over.

so i tried ur check for the solenoid, it doesnt spin, but it clicks, as if its turning on and off...
i also took a jumper cable from the positive battery terminal, to the positive terminal on the starter solenoid, and nothing happened, it sparked a lil bit but no crank..
does this mean that the starter is bad? or something else?

if its clicking that means its trying to send power though it. now try jumping from the big post to the big post. if it doesnt spin then, then its the solenoid thats bolted to the starter itself.
