You will need a Fuel Injector Noid Light, a multimeter, and another person . One to keep eye on light and multimeter and another to crank car. Locate fuel injector and disconnect, insert noid into connector, have asstinant crank car. repeat on other three.

Noid light Flashes circuit okay, noid light did not flash power or on/off signal from pcm is missing, noid light lit brightly but did not flash pcm is shorted to ground. So before you buy a new computer, get a wiring diagram for your car and check the wires connections.
