91 eclipse GSX fuel pump test lead junction

[onerne]

Can someone tell me where the fuel pump test lead (in engine bay) junctions with the lead from the relay?,at the relay or somewhere else?

I am trying to test flow and flush fuel lines after a long hibernation and replacement of fuel pump, cleaning tank and replacing timing belts, idler pulleys, etc. I have no power (12v) to black/white wire at fuel pump connector in trunk area when jumpered to battery positive. Ohmeter shows the lead is shorted to ground.

I plan on removing console to access relay and troubleshoot, but it would help if anyone knew approx. location of this junction.

Thanks

This is why you should own a factory manual. It's all in there. A-55

Thanks for the reponses,
I had found and used the test connector (#55 jumpered to bat +) previously but did not get 12v to ground at fuel pump connector(black/white wire). dvm shows this lead (disconnected from bat+) is shorted to ground and I need to find where it is connected to lead from relay to pump(probably at pump relay base) but schematic is not that detailed(I am using schematics from workshop electrical manual)

This may be relay or ecu related

I will remove console and troubleshoot-sorry if my description is not the best
Thanks again!

If you use the check connector it isnt ecu related. Check connector bypasses ecu. Could be fuel pump relay. If you have the pump rewired check that also but the stock connector at the pump should get 12v.

Repalcement pump powers up when wired direct, further checking I found fuel pump test lead was w/r instead of b/w and was wired to connection 9 or 10 on relay base instead of 2. A lot of work due to miswiring at factory( I am original owner w 52,000 miles and have never touched the wiring)
Hopefully 12v on terminal 9 or 10 when I tried to use the test lead did not cause any ecu problem.
I forgot whether test lead was wired to 9 or 10 but will verify
I will know soon
Thanks

There is more than one blank connector on the firewall. I dont have the circuit diagram handy but I doubt there was a factory mistake
