I would like to check my injector pump relay before buying a new one, but not sure how. Has anyone got any suggestions? Huh

Hi. If you have a multimeter, you can check the coil for resistance; if you get a very high (over a few thousand ohms) or over range then it's blown Wink, even better connect the coil to a 12v supply and see (hear) if the contacts close and put the meter accross the switch terminals to see if they close/open. Look on the top of the relay and you'll see a diagram, the coil terminals are the ones linked by the little box shape. Other than that you could swap it with one of the same type...

Another way is of course to substitute with one you know is good and compare results.
