with this code you do have a electrical problem from the pcm to the relay, i will look up what you should do next...
THE FIRST THING TO DO IS FOLLOW THE FLOW CHART FOR THE CODE... IT IS NOT FOR THE RELAY AS I THOUGHT IT IS FOR A PCM INPUT............. HERE IS THE FLOW CHART FOR THE DIAGNOSIS.
CIRCUIT DESCRIPTION The enhanced ignition system uses the crank sensor in order to provide the timing input to the Vehicle Control Module (VCM). The VCM uses this reference pulse in order to determine the individual ignition spark timing for each cylinderOnce the VCM calculates the ignition timing, the ignition coil module on the Ignition Control (IC) circuit receives the timing signal. Each timing pulse received by the ignition coil module on the IC circuit triggers the coil module in order to operate the ignition coil. The secondary ignition voltage is induced, and then the secondary ignition voltage is sent to the distributor for distribution to each spark plug.The IC signal voltage ranges from about 0.5 volt to 4.5 volts.CONDITIONS FOR SETTING THE DTC
ACTION TAKEN WHEN THE DTC SETS
CONDITIONS FOR CLEARING THE MIL/DTC
DIAGNOSTIC AIDS A poor connection, a rubbed through wire in the insulation, or a wire broken inside the insulation will cause an intermittent.Check for the following conditions:
TEST DESCRIPTION The numbers below refer to the step numbers in the diagnostic table.

The main thing you need to do is check for voltage when the pump is plugged in, it must have a load on the circuits you are checking, you can not rely on the voltage readings with no load on the wires, back probe the connector at the pump, use two paper clips pushed in the back of the connector, then check for 12 volts, if no 12 volts then move your ground lead to frame, if you have 12 volts then it is the ground wire, if still no 12 volts, then it is between the relay and the pump, the most common place is the terminals where the relay plug in.
