My polo classic 1.6 is switching off while running. What the cause be. I cleaned the injectors, replaced the coil and the fuel pump.
no year told nor country how sad is that, going Generic,
made 1975 to NOW, must we guess cars? and vast evolution ?
but Polo not sold in USA (huge hint there)
I presume it burns petrol both fuels had 1.6L diesel too TDI
yes spark coil is clue, only Coil told.
guess #1 engine stalls. PETROL
stop guessing or go broke fast,
there a can be 50 causes will; you guess 50times, can I watch?(evil face joking) ouch took a bath in fuel on a guess wow. that is brave.
not told at all:(and key to not going broke)
told the story and evidence ENDED at the STALL> !
1; fails only hot or cold engine or both
2: using right foot (pumped) can not save the he stall.
3: did it restart fast after the stall .
4: was engine overheating?
5: did any other things 12vdc electrics things vast on car fail at stall>?
6: alternator tests pass? 13 to 15vdc at idle.
7: no loose fuses?
8: at stall and parked, safely , is spark dead? a test all techs do.
yes /no , did you know all EFI engine on earth cut fuel instantly if spark is detected bad by the PCM (no simple misfire P030x)
9: scan the PCM at or just after the stall? oops. never skip scans.
10 at restart did CEL/SES/MIL cluster lamp glow running?
can it be made to fail parked, in your drive way? or garage
if yes, causes are 10x more easy and safe, than while driving
but I own a logging scan tool so can drive and log all DTCs live or stored, and makes work 10x more easy.
and some errors take 3 hits top store, so we have a pending key on the scanner to find those too.
that is it for now we can peel the onion as deep as you like.
using tools and basic skills.
if will not restart say so and say it cranks fast
and do Add, 5%throttle crank to check for IAC dead.
or do add WOT 100% throttle to clear floods (petrol crazy rich)
never mess with fuel parts, if spark is bad on any cylinder
or that invites adding bad parts to the car, now has 2 or 3 things bad.
no fun there, and huge down times guessing wrong.
it is super easy to buy the wrong parts guessing. zero fun there.
stop throwing parts.
please. and no the PCM is not bad. no ,no and no.
