With the ignition in the on position, check fuse 11 in the Battery Junction Box (BJB) under hood with a test light or voltmeter. If it checks out ok, pull the electrical connector at the coil pack. With the ignition on, back probe the connectorís number 1 terminal (Red Wire). If you donít have power at this terminal, youíll need to pull one of the fuel injectorís connector. With the ignition on, check the connector's # 2 terminal (Red Wire) for power. If you donít have power go back to the BJB and remove the PCM Power Relay (#47). With the ignition on, check terminal 86 in the socket for power. If you have power, check terminal #85 to ground. If the ground checks good, replace the PCM relay.
