Question about 1993 GMC Safari
Looking at your brief description can I guess that when warm the starter turns slowly? as if a flat battery?
If this is so then the starter windings and armature are possibly cooked??
Have you recently tried cranking the engine too much? or with a poorly charged battery?
When cranking the starter gets very warm and if not left to cool after 5 seconds of cranking can cook the wiring/armature internals of starter.
When your engine is cold the Windings/armature are too so will turn easier, but when warm all internals are expanded so more drain and heat! then causing the starter to revolve slowly taking a lot of power from engine and ignition circuitry.
This can also be caused from trying to start a vehicle with low battery, Volts go down Amps go up cooking/frying the winding/armature.
I am suggesting this as all I have to go on from the description STARTS COLD BUT ONCE IT IS WARM???? I hope this helps,
If it does please remember to press FixYa button as I have taken a lot of time to post the response.
