WALBRO fuel pump.

[jambunk86]

hi guys.

not really la dude.dont really have time for my car.busy with my industrial training now.to think about it,i cant really do anything about it right for now.just the matter of time the problem is solve or not.i dont think i can do anything if the pump is broken/cant perform at its best.

i've already done the wiring and stuff and manage to get 12v at pump socket.and now my fren advise me to go for grounding wiring first then later check other thing.i just play slow now and not to think too much about it.

now just running standard ecu reading.the respond is better then before.a lil.i dont know because of what,but i can fell the diff.just change the pump.

but still worried about the a/f...affraid that im running lean all the time. :(

if you are afraid of running lean, go to a place that can read a/f for you using wideband. I have one should you need some help.. but I'm in Penang.. hehehehe

The other thing is that you may have a clogged fuel filter... did you change that already?

hi bro i also face the same problem recently changing to wallbro. the pressure only reads 2.5 bar even at WOT. i check parallel voltage going into the pump only 4.5V idling and 8.8-9.0V when high rpm. the culprit is the supply in my case. put relay for direct supply from the battery. problem solved. it can even give me 80psi++ at wot. but offcourse i dont need that much. reset to where it shuold be.
