We cannot get our Volvo 2003T to spin at decent speed to start.
Fuel is ok. Bled the low pressure side, and get a good squirt from each injector when loosening the nut.
Cranking is slow, but starter draws about 200 amps, whereas it used to draw about 120 to start.

is it possible that starter is partly burned out ?
I can turn the engine by hand on the alternator drive pulley with the valve lifters up, so I do not think the motor is damaged or jammed.

I plan to take ate starter off when I get back on board.
What to look for?
What tests can I do with voltmeter and ammeter and simple tools ?

Thanks in advance for the usual competent advice
