Ok, so one day i drove to go eat with the folks, turn off the car go in and eat, 20 min. later come out and try to start the car. Try to turn it on and get a permanent CEL, No main relay click, and the fule pump doesnt turn on. I had to have it towed home 30 miles away with no road side assistance. Anyway I get home and do some research and come up with a few possible solutions. I checked all fuses under the hood and in the car, i replaced the main relay with a brand new one, i sanded and re tightened the ground from the thermostat, and i tested the code with the paperclip test and got no code(code 0 if im correct). my last resort is the ecu is shot or i did read that one guy had a wire from the fuel pump that snapped and this happend...but i am a stereo guru and unfortunately have a semi-wall in my car that so happens to be sitting over the top of the fuel pump cover...if there is any other help that you guys could give, it would be appreciated.

BTW i had a shop put in a new timing belt and water pump, but today i found out that they didnt hook up the ground that connects the valve cover to the body...

You might've found your problem then.

Boomboy14

what? the ground, nope...does the same thing...

Loose ECU pin? Have you tried jumping the main relay to verify its operation??

Boomboy14

where would i find the ecu pin, on the ecu itself? its a brand new relay.

Mot Gnuoy

Just because it's brand new doesn't make it perfect. Ask some people that have bought a few honda oil pumps. Jumper the relay to see if the fuel pump turns on. if it does, you're probably just not getting the ECU signal to turn it on. Check the pins at the harness of the ECU.

how would i go about jumping it?

try another ECU

Mot Gnuoy

another ECU would kinda be last resort. just unplugging yours and plugging in may fix it but in reality it could've been a loose pin that you just accidentally pushed back in.

no matter what it is im sure its the ECU. the cel code 0 is why.

Mot Gnuoy

Had CEL0 before on a shitty obd 0-1 harness.

how would i test the relay...im not so good with cars and need step by step instuctions if possible...i have the main relay in my hand but how would i test it without power...dmm or what

Mot Gnuoy

you need power to test it and a multimeter . I posted the link. Just take a deep breath, read, and do it.

my relay doesnt have a #4 terminal

accordingdone

= ownage.

checked to see if i have spark and i dont hink i do, i used a spark tester, plugged the tester into the wire and then grounded it onto the - batt termianl and no spark, i might have done it wrong but im not sure...

hey im having the same exact problem i have a 2000 civic dx wit a 99 GSR swap. car didnt want to start but cranked. some dude actually get it started for me he is a honda now it all so i can make it home. He told me it was my fuel pump relay.

Ivanek00

so i look online and i see that a main relay and fuel pump relay are the samething so i swap out the main relay and it started up drove it and guess what it cut off and didnt want to start. lucky me i had the old relay and i swap it out car started and i got back home.

i did a google shopping search and found a different looking fuel pump relay im guessing it goes in under dash driver side fuse panel i will be swapping it out tomorrow ill keep you updated if this dont work then ill swap out the fuel pump maybe it died out
