Well now that i got ur attention
My fuel pump is not coming on , its a walbro 255, so i checked my plugs on top of the fuel pump and it was dirty. Has some kind of a plaster stuff in there so i tought the connection wasnt good. I played with it cleaned it with wd-40(couldnt find the electrical clearner spray), shot it with air compressor and put it back on and it worked . So later i hop in my car and start it and think to myself its all good then i kill the motor and try start it again and nothing, fuel pump silent.
Is the Plugs the only thing to chk, should i just buy all new plugs from honda???

wiring issue. check the main relay too.

TurboTeG4

Wel i cleaned the wiring clip more and now i test for voltage with key turned and nothing no voltage, the fuel level harness has voltage though but the pump has 0. It was workin after i first played with the fuel wiring clip. I checked every single fuse i could find its all good. Any ideas

TurboTeG4

Anyone know where the power wires for the fuel meter and pump go to. The fuel meter has power but the pump wire has no power, could i just tap another wire from the fuel meter wire to the pump. The fuel meter has like 6.5 volts only , how much should the pump have.

Its the fuel pump relay, its under the dash and it costs like $25. I have the same prob after my swap. Some times the fuel pump wont come on so the motor will use up the fuel in the lines and then die, now I always listen if the fuel pump primes if it does it will start and run normal and will not die. When it doesen't prime I just wait a few minutes and try again and it works, it stranded me at a gas station first time I went to fill up my new hybrid but after like 2 minutes it started and I left.

Sunof a BITCH spent 68.00 bucks put in the relay and still nothing no click nothing wtf do i do now im upset!!!

TurboTeG4

0 power by the pump goin to take off back seat AGAIN 3rd time , anyone know where under the hood i can chk for volts goin to the relay???????

acydphryck

what he said...

TurboTeG4

Well i chk the harness that plugs into the relay
1 3 5 7
2 6 8

1-constant power 3 power with ignition 5 power/ignition 7 PUMP no power??
2 ground 6 no power 8 power/ignition

I take it terminal 7 is the fuel pump because it has the yellow and green wire which is the same by the pump
this is for a 1993 civic so far 70 bucks down the drain
any suggestion PLZ let me know, i might end up having to rig up a power line to the pump to take it to the shop if i cant trouble shoot it myself

TurboTeG4

terminal 3 should be by itself 6 with 5 and 7 with 8

TurboTeG4

Well even if i bypass everything and tap power to the fuel pump from the harness the car wont start. Seems to me that whatever is giving the pump power is also not permitting my car not to start. Now seems like im goin to have to tow my car to the shop, im thinkin of taking it to the honda dealership and let them do it. They should no more about wires then the local performance shop what do you guys think.

do you have power to the ecu??

TurboTeG4

i assume so, there is power on all the wires exept the fuel pump, the blue wire comes when the engine is cranked.

Well today i came home with a injector pulse testor and i go to hook it up turn the key and the fuel pump comes on??Car starts?? Seems like a loose wire or something but where??I have a vafc hooked up to my ecu i checked all my ecu connections and all seems good. Now with the pump commin on i dont know when my car will kill over again if you know what i mean!

TurboTeG4

Do you guys think it could be a 02 sensor , cause my pump is not coming on again as expected. So its coming off and on basically , relay is new

TurboTeG4

Bump, someone else tells me its my ecu??
Anyone know anything!!!!My car been in my garage for 2 weeks!!

TurboTeG4

Turns out to be a Bad ECU problem solved

DCStreetHtch

so i do a swap in my car, as i mentioned above i had changed my ground and that solved my problem. well now i am going through the same thing as turbocivic4. could it really be my ecu. i am running a 2nd gen b16a, 95 civic si engine harness, stock 92 dx cabin harness wired for vtec and the jdm obdI b16a ecu????
my relay is new and so is the fuel pump... basically same story as above, anymore suggestions!!!????

My car was down for 2 weeks till my frend let me borrow a dx ecu from their shop. There is no fuel pump fuse , only the relay, if it was the main fuse a lot of things would not work. Anyways im waiting for my ecu thats in the mail from a fellow on honda-tech selling them. It was Very hard to believe that it actually came from the ecu, i would have never thought a bad ecu

DCStreetHtch

some ****** ground was blown and once fixed my fuel pump worked fine... now my alternator is not functioning... one problem at a time i guess.
