172 turning over but wont start

[jordan172]

as above, has been fine in this cold weather so far just came out to it now and its just turning over..

i have just taken the tdc sensor off and cleaned it.. still no joy

battery is fully charged as i have just checked that and put it in a trickle charge because i need to keep trying to start it.

any ideas? iam with the car now so can try a few things!

thanks for any help

 

[jordan172]

also, when turing it over the red immobiliser light is off so dont think its a fault with that?

 

[Sean6545]

Does the fuel pump prime when you turn the ignition on?

I would be suspicious it may be a tdc sensor pal! Need to get the codes read really and go form there!!!

When did you last start it!?? Just wne to it and it won't go?

 

[jordan172]

yeh it does. you hear it buzz

if i cant sort it i think its a trip to the stealers.:dapprove:

yesterday stated i 4 times went to work got petrol ect went to it this morning and it was just turning over

problem is it wont start so getting it out is going to be a problem as heavy snow is forcast and its really snowy here already.

i took my tdc sensor off and put it on my friends 02 pate 172 and his fired up right away

 

[SBV116]

[jordan172]

[SBV116]

I have had issues with the one of the 3 little brown ones before, but not for a loooooooong time! So can't remember which one it was! Im s**t! lol!

Has the 5 amp fuse blown near the relays?

 

[Fred@BTM]

right hand one is usually the dodgy one from memory

[SBV116]

thanks for the help guys i really appreciate it.

i will also check relays and keep you all updated.

thanks again for all the help

Clean the TDC senser - the weather wont help it in its location

could of flooded the engine as we had that at work with a 182 kept cranking we had every thing fuel and spark took plugs out and all wet. cranked over by hand with all plugs out cleaned up plugs and re ftted them and started straight away.
Worth checking lol

 

[SBV116]

Any joy?!

 

[jordan172]

Any joy?!

hi steve got this to try first

just to rule out the connetion.

but its a bit to cold and dark to do now.

the little heat shrink sleves just push the wires into them stripped and squash the metal bit in the middle?
i was going to krimp it but these came with the kit

 

[chrisj]

I had this problem the other day. Didn't come up with any fault codes when on a code reader.Take it you got stung for the fifty odd quid by renault too

yep:dapprove: £51 inc vat

how did you fix yours or is it still broke?

 

[chrisj]

Mine was the tdc sensor.Changed it and it started straight away.cleaned it but it made no difference.hopefully yours will be the same

ah you have given me some hope! thanks. will update once i have changed it.

cheers bud

 

[chrisj]

no worries mate.i know how you probably feel.mine drove me mad

 

[jordan172]

yeh worried sick its something worse. fingers crossed

 

[chrisj]

i was the same, but it does seem to be a really common problem so hopefully it'll fix it

 

[Sean6545]

You dont crimp them connections. You place the wire in them either side and heat the whole sleeve. The heat will melt that metal piece and bond them together.

Also note sometimes the wires swap positions. Just match the pin numbers (a,b) to the new plug.

ideal, cheers bud. just waiting for the weather to pick up

 

[jordan172]

right just fitted the new tdc sensor and it has made no difference at all

still just turning over.

any ideas before i take a sledge hammer to it?

a few more things i have noticed

1. driver headlight ajuster going crazy its constantly ajusting
2. when ignition is turned 2 clicks sounds like there is a scraping buzz kind of noise coming from inside the dash on drivers side
3. whilst turning over the serv airbag oil and battery light are on. this might be normal not sure?

 

[James.f]

Before you fitted the Tdc sensor, did you just cross the wires with each other first to find the correct way? i didnt and managed to put them wrong way, after about a month of piss farting about trying to find the answer i decided to swap them over and hey presto it fired.

The Airbag is nothing to worry about, (serv will come on because of this)
oil could be that its too low,
battery light is always on but will go off

 

[jordan172]

ah right. well the old connections were marked on the plug

A=yellow wire
B=white wire

new one is

A= yellow
B= pink

so matched them up yellow to yellow A-A
pink to white B-B

think this is right?

oil is full was serviced in oct

 

[James.f]

You have 2 oil's. gearbox and engine oil, so not sure if it could mean gearbox oil ?

Did you use the plastic thing to melt across them? i didnt because i needed to make sure it was the correct order first, i would go out and check for you but its freezing sorry,

But just losen them up then twist the ends so their tight and join Y > Y W > P then swap, it could be this, but not sure why renault have changed the colour of the wires tbh, its worth a try,

 

[jordan172]

no i didnt i krimped them.

yeh i could try changing them but cant see it being A to B and B to A surely?

i need a pic really lol

 

[James.f]

Its the new style you have ye?

I had instructions with mine even tho i followed the steps it was still wrong, but i was positive it was correct way untill trev on here said swap them and i did and it started no probz, its worth a try if it only takes 30mins

 

[jordan172]

yeh it is. it`s blue

the thing that makes me wonder is that we put my old tdc sensor on my mates 2002 172 and his car started first time.

 

[jordan172]

my friend is bringing the eos fault code reader home on saturday from renault

so will keep the thread updated for people with similar problems

 

[James.f]

Have you anychance changed the coilpack/Plugs ? if you can get your mate round and remove them from his car and fit to yours see if they start, if they start then atleast you kno they are fine

 

[jordan172]

hi mate. yep tried a new coil as paul ly_182 has a spare one and it had brand new ngk platinum oem plugs in oct...... so am totaly at a dead end

very strange as it was working perfect the day before it broke down

no signs of any problems or anything

 

[James.f]

Ok, have you tried swapping the decoder ring atall ?
