I have a 97 GMC 1500 keeps going through starters change flywheel wiring harness crank position sensor wondering why
Keep putting new starters on starts good at
first then starts grinding again after a few
cranks replace flywheel everything don't
Some type of alignment problem or torquing issue flywheel and starter not meshing correctly.
You might want to check the thrust bearings in the engine, see how in and out movement you get on you crankshaft.
