So, you have fuel, spark, and compression (assumed on all cylinders), but do they occur at the proper time in the crank cycle? Has this car ever ran for you?

Fuel pressure? Injectors? Fuel pump, pressure regulator, fuel filter

Didn't your mother teach you not to throw parts (or your shop teacher!)
Current Volvos:
1998 V70 T5, 112k sat 5 years, still in mechanical coma (finally at the top of the pile )
2004 XC90 T6 AWD: 186k, 60 on transaxle ( traded in )
1998 POS70 N/A: DD/training aid, 236k but really about 240k, I think...ABS module( passed on to son who sold it)

Did the PCV upgrade and it helped with the pressure.
I used ZionXlX's internal spring idea, but incorporated a EMT sweep for the 90*

3ft of the oil resistant 5/8" hose ( from a heavy equipment parts store )
4ft of the same in 1/4"
A relatively light compression spring
1/2" EMT sweep

$ 20 and change.

Don’t forget to remove the bracket from that starter in the right side

Volvo discontinued that and no longer replaces it

The two m10s and the pins hold the starter in fine.
