HI all,

not been on hear for some time so hope all is ok, my friend has just got a non runner williams on a N reg. just been trying to get it running and think it has a 1.8 16v ecu on it. it starts then cutts out it wont keep running. there is plenty of fuel coming through so it must be the spark or something thats cutting out? is this normal if its running on a 1.8 16v ecu ? its lost me and thats all i can think it could be any ideas ???

many thanks
simon :evil:

no it would run on a valver ecu..

are you sure the injectors are firing...

how long before it cuts out...

It'll run but when you do get it running well don't be doing a huge amount of driving on the 16v ecu, get a willy one as soon as you can..

HI THANKS FOR YOU REPLYS.

it cuts out straght away, you turn the key it starts but no matter how much you try and rev it it justs dies instantly. its strange. there is fuel getting to injectors so i dont know what it could be if there is no power to the injectors ? the injectors must be opening at least one time or it wouldn't keep firing ?

i also have a Dimma clio that i cant get started and there is no power to the pump on that.my mate did some welding on it and forgot
to disconnect the battery no thart wont start. renault said it mite be the main fuses but i cant find a main one like there is on the megane's any idears onh that one as well ???

what you think ?

regards
simon

Sounds like the williams is immobilised somehow maybe?

What makes you think it has a 1.8 16v ECU? Checked the code on it?

Not too sure on this but the PH2 16v ECU has an immobiliser, and although the Williams doesn't, that could be causing a problem? If it's starting fine then immediately cutting out regardless of revs etc then it sounds like that sort of thing.

ye iv checked the codes and it def a clio 16v ecu and its got ph1 in Black marker pen wrote on the top of it.

iv got some other ecus that are off clio 16vs so i mite try them on it.

cheers

sound the the immobaliser in the ECU you need a phase 1 ecu for it to work.

I have a gunner chip i can sell you which i have been told can be fitted to a valver ECU to run a williams.

there hard to fit thought arnt they? soldering and stuff ?

AndyFielder

yeah they need soldering etc...

iv got a williams hear so mite try that ecu but if it dont work then ill be back on hear !

cheers

If it fires up its not the immobiliser surely?

Had a look at the ISCV?

SIMONCLIODIMMA

22-01-2009, 14:16

no i have a p reg clio and when the immobilser kicks in it wont start at all. with the williams its firing up for about 1-2 seconds them stopping every time. its got to be something simple ???

cheers

I have an M-reg Clio with a Phase 2 valver ECU and when immobilised the engine fires up for a second or two before dying, as you describe in your case. Sounds like it would be worth trying a Willy or Phase 1 valver ECU (the type without the immobiliser)? I have a Willy ECU you can try if you are near Essex/London?

iv checked the ecu and that is the 1.8 16v ecu S101715103 so unless thats faulty i dont know.

103 is a Ph2 ECU.

Personally I'd go over it completely if it's a car that needs TLC.

Check:
ISCV (clean it as a matter of course anayway)
Throttle body (as above, clean it)
Distributor/rotor arm
Coil pack
Spark plugs
MAP sensor (make sure its plugged in!)
TPS
Flywheel sensor
CTS

were is the map sensor ?

SIMONCLIODIMMA

22-01-2009, 15:58

i have 2 101 ecu and ?

Wobba

were is the map sensor ?

Its the little black box on the bulkhead with a vacuum hose and eletrical plugs going in it. It sits in the engine bay directly in front of the driver. I think mine did that when I unplugged it.

i know what your on about iv already checked that !!!

Thats exactly what mine does , so you'd need the ph1 ecu

does it start every time like that or just the one time then dosn't start at all ????

If I don't turn the immobiliser offf it will start up but it cuts out straight away

i have 2 101 ecu and ?

They are 19 16V ECUs iirc and should do the trick to get it running... but as above find a williams ECU asap

SIMONCLIODIMMA

23-01-2009, 14:56

is there anything that can be done to the 1.8 16v ecu to convert it to run with the williams ? like group A/N chip or anything else rather than getting another ecu ???

AndyFielder

23-01-2009, 15:23

if you got a phase 1 ecu you can fit a gunner chip to make it run the williams map i think

SIMONCLIODIMMA

23-01-2009, 15:28

does this give better hp ?

AndyFielder

23-01-2009, 15:28

a little bit yeah.. its mapped for 97 ron fuel

SIMONCLIODIMMA

23-01-2009, 15:33

i called hill power and he says and uprated chip for the williams would be ok is this true ??

AndyFielder

23-01-2009, 15:39

I dont understand where all these questions are from.

Gunner chip has a modifyed williams fuel and ignition map on it, mapped to run most efficently on 97ron fuel. Will give you a bit more power becasue of the higher octane fuel.. Will run fine on 95ron fuel just uses more of it per mile.

Put this map in a valver phase 1 ECU (no immobaliser) and it should run fine.

Andy

SIMONCLIODIMMA

23-01-2009, 15:42

sorry ok what i mean is i called hill power about a uprated chip. he told me that they do a chip that will give it about 15 hp more and it can be used on a 18 16v ecu ??? does that make more sence ???

AndyFielder

23-01-2009, 15:48

Yes it does.
But i would have thought his was alot more than £30 ... im not going to quote gains on the gunner chip as i have never done a direct comapison between it and the williams chip.

But it does give gains and a raised limiter which is ace!

SIMONCLIODIMMA

23-01-2009, 16:19

is that the proper name gunner chip ? just had a search for it but cant find anything. i mite have that off you for £30 does it come with the cradle that it sits in ?
