Fuel Accumulator

Like I said it is the spray that counts and the only way to test and clean them is on a Bosch machine or one that can test these. It will analyze the spray thus the wear of the injector. I do not see how you want to test them with a volt meter.

Nissan Maxima has an electronical injector. Your Mondial has mechanical ones, which mean no voltage to operate. Merely fuel pressure that is distributed via the fuel distributor Aka the "spin" Our cars are ancient compared to the Nissan

Here is such a test. Diesel or petrol, it would be the same sort of test.
