If this solenoid fails you may experience:
Equipment will not start
Equipment will not start hot
Equipment quits when it gets hot
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.
