:roll: schoooooolboy, fingers crossed its fried ecu and not some wires buried in the loom somewhere

Yeah, as above.
First thing to try is a different ecu.

99% its ecu, its easy to damage.

incorrect mate, M-reg is Mk1 Phase 2 and im pretty sure thats anything from 1994 onwards and they had immobilisers

SIMONCLIODIMMA
23-01-2009, 13:12

Do you have an alarm on the car? My alarm on my old nova GTE fooked up and it cut off the fuel pump. Alarms normally cut off the coil, fuel pump etc

SIMONCLIODIMMA
23-01-2009, 13:15
no its not any alarm on it at all . something is stopping it but im lost and there is not anything else i can test i dont think ???

Try hot wireing the fuel pump to the battery just to see if it works it may have some left over old alarm on it?

If the engine is still wont run with a williams ECU, youve fried a load of wires somewhere, not good.

To hotwire the fuel pump, find the white connector in the relay box, that looks like this..

On the bottom row there is a white wire in the middle, you need to apply 12 volts straight to it (on the interior loom side), and the fuel pump will spark into life straight away.

i will have to look at the wires. when he started the welding i heard a pop so i said what was that so i looked and didnt see anything or smell any burning anywhere but its not started since. i assumed it must have blown the ecu so got another off a 19 16v but not working on that or the williams ecu???

thanks for the photo Laine_16v i will have a go now and let you know if it fires up.

Just to confirm with you put the 12v on the middle pin of white female connector of the loom, not the male connector as shown in the picture.

thats strange i have 3 clio's hear williams and 16v and non of them have them wires in that white plug ???

SIMONCLIODIMMA
23-01-2009, 16:39
well they have the white wire but no wire on the other side of the plug to connect to it ???

like mentioned ,the body panels are hiding loads of wiring underneath

its a Dimma we are restoring as a show car (if we ever get it running) it was at the top of the car near the boot lid. he only just touched the car for a second but it made a pop sound like something had blown but i dont know what ???

Im nt sure where the fuel pump is on a williams as iv never took one out. Fuel pumps are normally in the top of the tank under the back seat, unplug it take it out then hot wire to the pump to see if it works. Just to make sure you have checked every fues?
