Does anyone happen to know where fuel pump relay 2 is in the ETACS ECU?

 

[Splattj]

It's in the ETACS ECU. C-304 ETACS-ECU connector terminal No. 11 in C-304

13B-FUEL PUMP SYSTEM

(1)Remove the ETACS-ECU. (2)Use jumper wires to connect C-317 ETACS-ECU terminal No. 6 to the positive battery terminal and C-304 ETACS-ECU terminal No. 11 to the negative battery terminal. (3)Check for continuity between the C-307 ETACS-ECU terminal No. 1 and C-314 ETACS-ECU terminal No. 1 while connecting and disconnecting the jumper wire at the negative battery terminal. Continuity (2 ohms or less) <Negative battery terminal connected> Should be open loop. <Negative battery terminal disconnected> (4)Install the ETACS-ECU. Q. Is the measured resistance normal? Go to Step 3. Replace the ETACS-ECU. Then confirm that the malfunction symptom is eliminated.

Thanks for the help! I will try to test that out today. Gives me a much better direction.
