Mystery Non Starting Turbo Xu10

[NFS 32]

Right. Some may know that I'm restoring my 205. So today I pulled out of the unit so I can do some work. Started first time on the button no issues pulled it out turned off the key about 4 hours past I fitted the boot and passenger door. I did no work on or near the engine bay. When to start it to pull it back into the uni and it was just turning over not fire. So I checked for fuel and even got another jerry can to go in it and there is fuel in the rail and believe there is fuel going into the pots. Checked for spark, I molgriped the 1st spark plug to the engines mount to give it is ground to test and no spark. So I checked the coil wire and admittedly they are not in the best shape (see first picture below) but for it to just not work when it was previously working is strange. I didn't not the conversion so I know very little about how it was done and looks to be a s*ite install. See below

 

This is the plug that goes to the coil and as you can see it was butchered by the previous owner. Now is this only meant to have 3 wire or is there ment to be a 4 black wire?

 

And also can someone identify these? They attach to the mail part of the loom?

 

And this one? It was dangling by the sump

 

 

Help would be appreciated thanks

The second pic if the lambda sensor wires there should be a big brown/ black relay some where I would start there or the crank sensor :-)

Thanks, the strange thing i cannot get my head around is that i started it fine to drive it out and then it wouldnt start to drive it in? what can magiclly die like that? coil? ignition module?

Its French? :-)

If the relay gets hot it stops the firing and if the crank sensor has gone it wont do anything because it carnt read the position of the engine other than that take all the ignition plugs of ie coil, spark amp ect and give them a clean

i will attempt to start it next time im at the unit, when the relay has cooled down thanks.

 

can anyone tell me what the 3 plugs are for?

last picture is for the idle control valve originally its pipes connect between the small hose directly above the inlet boost hose and the inlet boost pipe itself well it is on the original car it came from im at this snag on my conversion now

Okay, i have my idle control valve plugged in and i know it works i had trouble with the connections being in a bad state was was causing a rough idle. but i sorted that, could that be the 205 idle control valve? not the xu10 one?

if its not the idle control valve it must be the throttle switch plug its the only one like it under the bonnet so if thats already plugged in on yours too it must be a spare left over, having said that though on mine the throttle switch plug is brown and the idle control valve switch is grey as in your picture

 

oh hang on a minute how many wires in your white plug? is it 2?

AC compressor possibly? Certainly the plug on the later XU10 looms is a white 2 pin and is down near the sump, usually plastered in oily gunk.

sounds like the one lol. so what year is classed as the late loom? i have no histroy or envolvment of this engine conversion thansk

2 pin white on its own loom with plastic trunking whatever its called on my original loom is reverse switch

 

does it come out of the loom with the alternator light wire, oil pressure wire and the throttle sensor wires? if it does its definitely the aircon plug

Yeah i think it does will comfirm when i see it next, so has anyone had this problem before where it randomly just dies? actaully come to think about it, it did stall its self a couple of time a few days before it died, i would let it idle and about 3 mins later it would cut out. i thought it was a lack of fuel as it was low. but since then i have put 5 liters in and the fuel gauge is just under 1/4 so i doubt it slack of fuel this time.

yess, i found the issue, it was a pin worn in the plug that powers the coil pack. re shaped it and fired stright up very chuffed
