Ok, here's the story. I have a 255lph Walbro intank that has been in sevice less than a year and was working fine.

I just swapped in a B18B and also converted to OBD 1 and threw a Hondata S200 in there.

I ordered a new chip w/basemap for my setup from SGT.

Using starter fluid it will run for a few seconds, but it's not getting fuel (lines are empty when I remove them). I also noticed today the pump is not priming before startup.

I think I've run thru every troubleshooting step in the Helms and can't seem to locate the problem.

Replaced walbro w/stock, same thing no worky.

Tested for voltage and gnd at the pump connector, all is good there.

Tested the relay, all is good there.

Wiring also looks good.

Anybody have any ideas?

 

so u got power? and the pump is good? but it wont prime. and the fuel lines are empty.

hummmmmm

 

Yeah...f'n crazy man. I'ma go f with it some more, but it's getting chilly out. Have to wear TWO sweatshirts now that it's back together and I pushed it out of the garage

 

i hate to be captain obvious, but does it have fuel?

add a gallon or two to make sure

 

That was my first thought....gauge said full and I was thinking bs, but when I pulled the pump sure enough, almost overflowing. DAMNIT.

 

u did hook up the fuel lines to the pump right

 

Yeah, but it's somthing electrical...the pump isn't coming on for some reason. I hope there's not anything wrong with the ECU. I bought it with the Hondata second hand but new. I know the guy wouldn't have tried to jack me either so if it is bad he wouldn't have known. DAMNIT again.

 

humm, if u narrow it down to the ecu i will let u plug in mine.

 

it is very easy also to mix up the fuel return and the fuel supply line. check that as well ...

 

mine is not priming occasionally(walbro 255lph). i have to pump the gas while trying to start it and it will prime and start pumping.

 

my friend had the same problem with his stock fuel pump in his accord. Honda determined it was some fuel pump relay. He said it was like 40 bucks and seem to do the trick. If that helps any.

 

hopefully this might help somebody in the future...i'm thinking maybe i wasn't getting a clean contact at the pump or maybe it stuck after sitting up for like 4 months. I got back there and hooked it up to straight power and it came on so I let it run for about 15 seconds.


bwaaaaaaaaaaaa is what my neighbors heard at 11 pm after that

it's alive...it's aliiiiiive!!!

 

whoever said the fuel pump relay is probably right. I'd be checking that out, I've had two go over the years.

 

I had actually checked it out per the Helms already. Read the above post to find the strange solution I stumbled upon.

 

I guess it needed a push start..hehe

 

did pushing the gas while starting it do it?

 

haha

 

What are the signs of the fuel pump relay going bad? I think my car is starting to do the same. However, I do hear a relay "click" sound when I turn my car in the "on" postion. Is the "click" sound coming from that fuel pump relay? or ECU?

 

Good find Hatchblack, sometimes it is those obvious things that are confusing. Good Info!

 

Check your main relay

 

I agree ... i had the same problem in my Integra and I used the mainrelay out of an Accord (cause they are all the same) and it worked.

 

yeah I thought I killed a pump in my prelude but really it was a main relay... replaced it and zoom zoom.

 

The problem was already fixed.
