New fuel pump not turning on..help!!
So I just put in a new fuel pump but when I put the key in the ignition turn it to on the fuel pump dosent go on....now I tested to see if the fuel pump works while it's connected to the harraness by using a car battery and some wire and plugging the wires into the plug then the fuel pump turns on so it's not the fuel pump and I don't know what it could be...can anyone help?!?....also I put in new fuel injectors and had to put in new connectors for the injectors could it be the plugs wiring are backwards?!?

Best thing one can do is buy a service manual, and take a look at the wiring diagrams, you can then do the necessary troubleshooting tests. I would suspect a relay problem, or wiring harness problems.
What are you working on anyway? if it's a Honda, probably main relay issues. |
Yea that's what I think but not totally sure and it's a 98 Honda civic EX I'm turboing
|
Also I test the plug where it connects to the fuel pump and there is no 12v power coming out of it tested with a wire by putting the wire on the negative terminal of the plug and touching the positive and there was no spark coming out of it
|
You don't own a multimeter do you? and your building a turbo car? have you checked your fuses? The main relay also is controlled by a time delay, key on, pump runs momentarily, than it turns off, you can hear 2 clicks of the relay when you turn the key on, one for pump on, then pump off, it turns back on once you crank.
|
Yes I got a new relay and that's what happens so it works fine but the pump still dosent go on even momentarily
|
And the fuses are fine I checked them. And no don't own one so have to use wires to test for voltage.
|
if you spark the wires to test for voltage, you will blow fuses
go to your local harbor freight, or go here http://www.harborfreight.com/7-funct...ter-90899.html set it to dc volts. without a multimeter of some sort, tracking down voltage/wiring issues, you might as well cut all the wires and put them back together with wire nuts |
