Clio 182 cranks but no joy, Renault want £700...

[squirrelthedj]

Hi all

I was removing my aftermarket stereo, amps, speakers and sub from my Clio 182 (2004) so I thought I'd best disconnect the battery first as a precaution. All equipement is now removed and the battery is re-installed but the car wont start. It cranks for a few seconds but no joy. The battery is fine, ring decoder had been checked by removing the key blade from the fob and trying it on its own and by removing the decoder ring altogether. The AA have been out and luckily the bloke who attended had had 3 Clio 182's of his own and was very thorough. All fuses and relays in the cabin and engine bay are okay, but he found that there is no switching voltage going to fuel pump or the injectors.

When I was reinstalling the battery I connected the terminals in the correct way: positive to positive, neg to neg, but when I was tightening the terminals with the ratchet spanner I inadvertently touched the chassis the with the spanner. It made a slight snap noise but nothing major. Surely the car is grounded for things like this?
Also, when I pulling the audio leads through from underneath the carpet is it possible I may have disconnected something by accident? Is there any critical wiring that is lurking down the centre channel of the car between the seats and the gear stick?

Renault have connected it to their ZX Spectrum 48K Diagnostic thingy and reckon they can't clear some fault codes in the injection computer and want 700 bucks to replace it and they are not even sure it's definately at fault.

Any help or expertise would be greatly appreciated as I really hate walking and hate giving £700 out even more!

Thanks

Steve

is the imobilier light goes out ?

Is the car getting fuel?

Are you getting a spark?

Is the battery any good?

Is the starter sounding like its enough power to start the car?

Tried bump starting?

Do not pay that ffs. No way it's ecu related. Where were your wires threaded through the bulkhead?

Have you looked at the car then??

I know someone who has spiked a ECU doing the same thing.

Where did you ark it out too? As the ECU is around the battery area isn't it?

Whats your earths like?

you didnt hit the fuel stop button thing ? i assume all clios have these, including 182s

did he pull all fuses and check them ? even the big main one(s) ? i would check with a multimeter for continuity. he might have had 3 182's, but also could have been a muppet. how did he check the relays ?

getting a spark from the leads/plugs ?

Only the Mk2 phase 1's have the fuel stop button

and when you say cranks for a few seconds but doesnt fire ?? does it stop cranking ?? or keep trying as long as you keep the key in the crank position ?

ahhh right, worth a shot, thanks !!!

We need to know what the immobiliser light is doing before we can help you?

Obviously not, but 99% of the time, when this issue arrise, the diagnostic kit can't communicate with the ECU due to the immobiliser being active or (and most likely) there is break in the can-bus wiring to the ECU from the UCH, so naturally they assume it's ECU related, change it and ....... shocking, it's still not working. He would be better getting a second hand ECU/UCH/Key set and trying that to rule it out, but i'd be amazed if that's not a waste of time.

Flashing immo light = either faulty key, code, decoder, or uch

Solid red immo light = break in canbus wiring

I just solved my solid red immo light issue and a wire from the ecu to the white multi plug was broken.

Managed to solve this myself with the help from others on here.

I refuse to ever take the car to renault

99.9% of the time its never the ecu thats at fault

As people have said, what is the immob light doing?
