Starting problems

#1

Post by zveki » Fri May 18, 2018 4:51 pm

First of all sorry for my bad english i suck in grammatics so don't judge me :icon-lol:
Dont know where to begin i bought my hyundai coupe 2.7 v6 2004 lets say cheaper then others on market i knew it i will have some problems but on every used car u need to change vital parts even if they have bill of parts in ours country u cant trust that cause dealers will sell anything for money even theirs family
my problems started after 3days i couldn't start it from first time always like 2-3-4 times and after 1 month i couldn't start it like 10 min or so really annoying so i went to car mechanical i knew they know something about cars but they all know how to connect to computer and see there is no errors and saying to me we cannot help u i went to like 5 or 6 until i decided to go to hyundai house i told them don't connect me to computer u will not find anything they told me we will fix it just drove it to us after i drove like 70km all they did connected me to computer and told me we cannot fix it wtf is wrong with car mechanics that was my last hope nobody didn't want to see what else can be so i decided to take it to my hands and tried with elimination process
i bought ecu,bcm,control table,keys with all doors locks key fobs,all cables outside and inside,and i changed it all by myself only didn't change cables cause i need car every day i have some knowledge and autodata to help me but i still have same problem so every help would be great what else to look in to.
tnx in advance and sorry for long text but i m desperate as u see :D

Could be immobiliser issue, could also be crank sensor.

As far as i know the immobiliser is seperate to the bcm and must be changed with the bcm as they are coded to each other

If you've changed the ecu, bcm, control table, keys with all doors locks key fobs I agree with Robbo and would lean more of a sensor problem and it's usually the crank position sensor.

The immobiliser code is programmed into the ECU, all the BCM does power the aerial which is the coil round the ignition barrel. The BCM receives the signal from the Transponder chip in the key and then sends a binary code to the ECU. If this matches then everything works. Because the BCM is matched to the ECU then just changing one will cause issues with the communication. It may work at times but there will always be something that does not due to the mismatch.

the crank sensor is a comon thing on v6s as the wiring runs near to the front header its goes brittle and get damaged.

From that picture it looks very similar to a dashcam or reverse camera fibre optic connector. What is at the back of it?
