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.

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.

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.
