i took this set up out of a running car did all of the wiring my self put it back in and now the fuel pump relay wont work i have cheaked all the grounds and power over and over i can jump the relay and the pump works i have injector palse fire every thing but fuel help!!!

Make sure you have the right kind of power going to the pump,,as in ACC not Start ,,,Hot when on. Also make sure your fuel lines aren't crossed.

Or you can just spend 5 minutes and clean out the jets... Ooops.. that will only work on an AC engine.. I forgot that you cannot trouble shoot a WC engine..

the fuel pump will not power up when hooked to the comp. but when i bypass that wire the pump works fine but the pump runs all the time

Is the fuel pump relay clicking? Try disconnecting the battery overnight too.

Does the ecm provide power or ground to the relay and is the relay wired accordingly?

this is a 1994 ej2.2 set up

that diagram is obd1 only has 1 o2 sensor

its wired just like the digram the lg/b on D23 is the wire that is not working

Perhaps the ecu is bad. Might try another one.

can the fuel pump run on the ing. switch or does it have to run on the comp.

It needs the computer to tell it when to run.

Check the relay, it should run off the ignition since it has a fuel return, as well.

Usually the comp. just earths the relay for the pump, so if the comp. is bad, the circuit is usually fused open and it runs all the time rather than never switching on.

If you can not figure out why it does not work from the ECU, I see no reason why you can not connect it to you Ignition circuit to run constantly. The system has a fuel regulator to maintain the proper pressure so it should not matter.

not a terrible idea. although I would only use it for troubleshooting. in the long term, I think letting the ECU control the fuel pump is a much better idea.

Are you sure the ECU is turning on like it should? all power sources hooked up correctly? Do you have power to both yellow wires at the fuel relay?

The ECUs are much harder to damage than you might think. but not impossible. if you think the ECU is wired correctly, and the only issue is the fuel pump, hard wire and see if it goes. But I bet it's a larger issue.

yes both yellow wires have power if i by pass the relay it will start and run but i would like it to run on the ecm so im still working on it cheaking every thing

On my suby the comp grounds the relay, so make sure the relay is wired correctly

thats how mine is but no ground comes out im going to try another ecm i got to see if that works

Some suby 2.2 obd1 had a cluster of grounds that grounded to the engine. Double check your grounds too.

All else fails blame the computer, they don't care! Glad you found it.
