To check the solenoid, you can energize the front electrical terminal on the injection pump with a jumper wire - you should hear a distinct click as the solenoid operates. Sometimes they only cease to operate when they get warm. There are other causes for the above mentioned problems, so you should do a little diagnosis before replacement.
