what's up with my fuel pump relay?


Recommended Posts

I've just rebuilt the ea82 in my 1990 loyale and I've got the engine back in the car, but I wasn't able to start it up because the fuel pump wouldn't run. I checked the relay for power, and the two leads do have power. However, when I touched the test light to the ground (which goes to the ECU), the pump immediately began to run. So I temporarily setup to where I have an extra wire jabbed into the ground connector, and then grounded to the body. This way, the pump runs, but it runs all the time (when the the ignition is ON). I don't see this as a problem unless I constantly have the ignition on without the engine running, so I was thinking of setting the relay ground up like this pernamently. Am I asking for trouble by doing this? Or maybe is there some other fix that would work better? I zapped some electronics earlier and was thinking maybe it affected the ECU in some way to cause this? No other electrical problems apparent at this time though.

you can go with that, but put a switch in-line so you can turn off the pump if the key is on for whatever reason, not running

 

i myself would just run a hot wore, with a switch to the STRIPED WIRE on the pump, and the other one ground to body

 

you can run your wire along or under the center console, from the back of the console under the carpet, and under th4e seat thru the brake or fuel lines grommets

 

the dist triggers the pump when its turning, but it comes on for 2 seconds as soon as you turn the key to RUN(to pressurize

 

try connecting the GREEN TEST CLIPS together, then turn the key on, the pump should cycle on and off. if it DOES cycle, your problem lies elsewhere than the relay
