baka auxilliary fan

Depends where you hear the sound.
locate it first.
Check the areas of the fuel pump, power antenna, starter, ac blower, aux fax etc. radio. This accesories can cause sound especially when left turned on and can be heard during ignition.

[simplicity]

kung yun ang unang una mo naririnig before the click of the main relay, fuel pump nga
yun. sa akin ang sequence: turn on ang key, hum ang fuel pump, click ang main relay,
patay ang ilaw ng oil, CEL sa dashboard.

[sirmykel]

kapag nasa harap ka ng engine bay ng corolla 101 bigbody,
malapit sa lalagyan ng alarm at left ilalim ng engine support.

hindi sa aux fan, starter etc.

normal sound ng fuel pump is 3 seconds lang and after that wala na.maaring iba gaya ng sinabi ni 4gtootsie,kailangan mo muna pakinggan kung saan galing ang sound.try koeo.

the hissing is only heard for around 3 secs when you switch on, then goes away. it's not a loud hiss.

check it again, this time remove the gas cap, have a buddy switch on the car (not start, just on) while you stay near the gas cap waiting for that hissing sound.

tapos report back here for the next step

(fuel pump replacement is a bit difficult since you need to pull down the gas tank, but I've done it DIY. less than 1K labor niyan sa friendly neighborhood talyer)

tol, kung me diperensiya ang fuel pump mo, di aandar ang makina mo, kasi, EFI engines have a high pressure fuel delivery system. di kagaya ng carburettor type engines that depends only of the vaccum created by the egine.
So, if the fuel pump is malfunctioning, there will be no fuel supply to the engine

sir, anu po engine po niyo PH16?kung PH16 po dapat local version din yung Computer Box mo, kung surplus ang nakuha mong ECU box kailangan iconvert din yung wirings mo papunta sa ECU box mo. kasi iba yung sa local yung sa suplus ECU.malamang may tama na yang ECU mo kung di na namamatay Check engine mo.agapan muna agad po yan kasi mas malaking problema pag pinatagal mo pa yan.

if you hear the noise from behind you that is normally the fuel pump.

sir follow up question po.
wat if wala na noise na naririnig kapag i oon na yung engine?
dati naman meron pero ngayon wala na

[4JGtootsie]

What we usually do to check fuel delivery problems is temporarily replace rubber fuel lines with transparent hoses so we can see if there is pumping activity or air cavitation. Before assuming its the pump or the ECU I suggest you do his simple test.

*burjegol> Carburator type fuel system uses mechanical and sometimes electric pumps to transfer fuel from tank to filters to carb. Vacuum alone will not be enough unless the tank is level with the carb.

Hi guys! Any idea how much is the fuel pump replacement for a 2000 Honda City Type Z? Saan kaya nakakabili nito na mura? Banawe or Evangelista? TIA!

[speedyfix]

electronic fuel pumps should be around 2-3k and a couple of hundred bucks for the labor depending on how hard it is to get to the pump.

i own a honda city idsi 03, ayaw na magstart ng engine, pero ok naman yung battery, fuel pump problem daw sabi ng mekaniko sa kanto, pero dinala ko na sa casa to be safe....pero magkano kaya ang fue pump, and what causes its malfunctioning?

if you don't hear the 3 seconds hum when you put the key on start (not ignition) then your pump is busted. But if you can still hear it have it checked using a pressure guage. Usually nasa above dapat 35PSI yung reading. pag mababa na pressure palit na.

ang cause ng premature wear/malfunction ng pump is when you dont regularly change your fuel filter and allow less than 1/4 of fuel sa gastank.
