Is there any way or a chart on how to check the solenoids ? Wife's envoy denali motor had to be rebuilt due to 2 spun bearings . The 5 and 6 crank journal had bad wear only on the compression side of it . From what I have read a while back it could be bad injectors and the shop said could be bad DOD solenoid . The check engine light wasn't on at all . Any thoughts or input on what / how to check them much apretiated !
