1G No power to fuel pump

[Brab]

I have a 94 Eclipse, It won’t start. I have spark, I have confirmed that I’m not getting any power to the fuel pump by having someone turn the key while I check at the fuel pump connector for voltage.


I have read that the next step would be to check the fuel pump relay and ECM, I pulled the fuel pump relay and ECM from under the radio area, does anyone have testing instructions for the relay? I did a visual inspection of the ECM and it appears to be fine, is there any way to test it?


Is there anything else I should be checking?


Any help would be great, Thanks.

You do know that the fuel pump relay is only activated while the engine is turning (CAS pulses to ECU) right? So just key to ON won't do it.

I had someone turning the key trying to start it, I also used the jumper by the battery both came up no voltage.

It would be easier to apply voltage to the jumper and work your way back. Make sure you have power at the harness at the pump when you use the jumper.

No power from the harness at the pump when using the jumper. I would like to test the wiring, relay and ECM but can't find anything showing how to do this.

Is it a 2.0L Eclipse?

it's the 1.8, does the link still apply?

The 1.8 is different from what's in that thread and I haven't looked in a long time for what the differences are.

You're better off reading the 1G 1.8L wiring diagrams to see how things are connected.

Could you please tell me where I can find the 1.8 wiring diagrams online? Thanks.

Did you try searching the site for service manuals?

Had no idea, The last car forum I was on said it was against the rules to post manuals because of copyright law or something along those lines.

Anyways, Thank you.
