It should be like this:
At fuel pump relay with the key OFF:
P/B wire = Battery voltage (whatever the voltage is across the battery terminals, ie: 12.4v)
All other wires = Zero volts
At fuel pump relay with the key ON, engine OFF (for two seconds after key is turned on):
P/B wire = Battery voltage
G/Y wire = Battery voltage (zero volts after two seconds)
R wire = Battery voltage
B/O wire = Zero volts
At the EEC Power Relay with the key OFF:
Y wires = Battery voltage
All other wires = Zero volts
At the EEC Power Relay with the key ON, engine OFF:
Y wires = Battery voltage
R wires = Battery voltage
R/G wire = Battery voltage
B/W wire = Zero volts
BTW, these readings are all with the specific relay plugged in.
You need to disconnect the 60 pin connector from the ECM, and test for resistance between the battery neg POST, and pins 40, 49, & 60.
Next, test for voltage at pin 1 (key off), pin 37, pin 57, and pin 26 (KOEO).
Write down the results, and post them.
Take care,
