car was running fucked, took it to a garage near by they said it was the fuel pump so i got them to replace it with a walbro 500hp one but the car is still running shit kinda cuts on and off and stalls at idle.... maybe the fuel filter wasnt replaced i dunno any help would be greatly appreciated.

did you tune it once you installed the fuel pump ?

how is your air mass meter or air flow meter, (the lil electronic device that is connected just after your air filter

ive looked at everything the afm seems fine, i havent tuned it im still using stock computer do new fuel pumps need to be tuned?
the problem seems to be the same as befor the fuel pump was changed

clean your throttle with carby cleaner and a toothbrush
start and check again

disconnect your idle control and see how it runs then, if it runs better, it's the idle control, if its still crap, then it's not the problem

sorry im just giving you odd steps to try with no definite answer, just lots of trial and error

Thanks man all advice is helpful, fuck this is frustrating

clean AFM

check your plugs

change fuel filter

could have a leak somewhere too. check all hoses and joiners.

dont need a tune for a fuel pump but if you have changed injectors then you will

is your fuel pump re earthed why did they change the fuel pump did they measure the fuel pressure and flow and it was low? if they measured before fuel filter has something to do with pump and lines to the tank or if they measured after the filter could be blocked

the mechanic said the pump was broken so it was replaced, i cleaned the afm changed the fuel filter andchecked all hoses today and still have the same problem the spark plugs were changed recently i use iridium too so they shouldnt be gone...... could the coilpacks be dead??? anyone had this kinda problem ????

wow this problem sounds gay

well the easiest way to test coilpacks is to let the car run and pull out each one individually

if the car runs worse when you pull it out, then put it back in, that's not the problem
BUT if you pull out a coilpack and there's no change in the idle, that ones the problematic one

another issue could be blocked injectors, best way is to pull them out and send them to a mechanic to get them serviced, about 20bucks each MAX

or if you really want, just get higher flow injectors while you're at it =D

this problem is very GAY, hopefully get to the bottom of it soon thanks for the help

so turns out the problem is in the afm, its just old and broken when you tap it with a screw driver the engine shits itself, my question now is will an s14 afm suit my s13 with no problems as i can get one for free????

just go aftermarket
z32, can't go wrong

completly agree however i want my car on the road asap and the s14 afm wont cost me cent, unless you want to give me a z32 for free

haha well if it makes you feel better
my s14 has been incapacitated for the last 2 months and will be for the next 2 =(

Omg how gay is it so sick of driving my girl friends corolla , I
can't believe your cars been off the road for so long, now my mate with the afm says he's chucked it so now I need a new and don't wanna get a z32 cause I can't afford a tune, anyone got a stock afm lying around???
