It may be the ECM. There is a small transistor that provides +12 volts to the relay to activate it. The transistor tends to pop on it's own. Easy to replace it so don't toss the ECM if that is the issue.
At key-on, engine-off the ECM will power up the FP relay for two seconds. Need to key-off for at least 5 seconds before trying again.
Can check for power on pin A of the FP relay connector. It is the DK-GRN/WHT stripe wire. It is pin A1 at the ECM.
Also, make sure that the SES light turns on at key-on. If not then a fuse is blown or the fusible link at the battery is open.
