Re: Cam Belt timing

well starting from cold the lambda not working shouldn't make any difference as it will be in open-loop. How does it idle once its warmed up a bit? Sounds like you have tried all the usual susepcts - (have you tried some new ht leads) i would re-check your timing marks - only takes a moment to drop the lower pulley of to check the marks on the crank. After than you may as well look at this lambda fault although it really shouldn't affect the starting as i said.

didnt try ht leads yet, as i bought new on 14.4.2015
ht leads affect starting?
didnt let the car to warm up to check idle, but it is rly eager to stall

for timing marks they are good as i checked them on my other mk1, and i got it same 0 mark on gearbox and aligned with camshaft, i did 2 turns on crank and everything aligned again

Re: Cam Belt timing

well poor ht will cause no start or bad start and general bad running... As far as i can tell you have swapped out everything else on the ignition side so would at the very least look for flashing blue arc in the dark while starting/running. Or just sway them just to rule them out.

Re: Cam Belt timing

as in it might have diesel in? unlikely - diesel pumps have a bigger nozzle and don't normally fit in a petrol filler (that not always true and its been a while since i had a mk1 punto). Its done like that cause diesel in a petrol is very bad, whereas petrol in a diesel is no big deal.

Re: Cam Belt timing

well gonna take lambda from donor and re wire and see if that is gonna do anything
would bad lambda cause injector light to be on?
next step: change whole throtle body or only injector?

Re: Cam Belt timing

Lambda can make EML come on yes - hence the fact the ecu logged the error before... It can put eml up because its gone completely open circuit (i.e. totally failed and not getting a signal from it) or could do that from a wiring fault rather than the actual sensor failure. Remember the light is just an engine management light and has nothing to do with injectors per say but if you have another known working TB then swap the whole lot as that also rules out any of the little sensors on it, TPS, ICV, AIT.....

Re: Cam Belt timing

yeah it won't make any difference during startup and when cold, the ecu is running rich while it warms up... It could still log a fault but it shouldn't affect the starting and idling right after while cold.... So its doubtful the lambda is causing the starting and poor idle issue but that doesn't mean the lambda can't make the EML come on during that time.

Re: Cam Belt timing

the injector can be taken out and swapped but there is little point - the injector itself failing I have never heard of. But you could try taking the whole TB you have spare and sticking that on.

plugs dark? as in all sooty and black on the electrodes? did you clean them up before you stuck them back in??
