Alright chaps need a bit of help s2 rs turbo has no spark .. Soo traced back the wiring with the voltage meter and there is power going to the coil but no spark coming out as put a spark plug in the king lead and earthed it to the car and nothin! But I ordered a new coil from fleabay a Lucas one but the terminals where the live and positive go are shorter and smaller and the king lead connection is different can any one help? It says on the eBay ad it's for 86-90 escort rs turbos? But defo not right for my car...

wrap a little wire round +&- to pack them out for short term ,
king lead connection is a male on the coil ? or how is it different

beller

im no expert here but had starting issues myself no spark but power to the coil, found in the end it was a failed distributor (hall sensor)

mk2grp1

I would say dizzy too but he may as well try the coil first as he has 1

beller

took me a while to get to that point though after coil, dizzy cap + arm, leads swap and voltage checking, wire tracing and replacing wire from coil to ecu

It was really only cus i posted on here i got it sorted

mk2grp1

yeah its a shame they can`t talk

beller

maybe there is something in this modern usb laptop diagnostic stuff

forgot to add the starter seemed to turn the car over a bit faster when the failed distributor was on or maybe it was just mine

andrewmill

Yeah but there's no spark coming from the coil in the first place and that's before it gets to the dizzy , the new coil the bit where u plug the king lead in its like further down the plastic but compared to the one I took of after I compared them if that makes sence? And the terminals were a lot shorter and not as thick so I crushed them with a pliers to make a better connection while I tried to get a spark from the king lead

andrewmill

It happend one day car was going a dream was sitting at traffic lights and the car just died if that helps anyone that's had the same experience

beller

i think the coil gets an instruction or earth from hall sensor via ecu so i think thats why
so no earth no spark

andrewmill

Can you buy this hall sensor by its self or gotta buy whole distributor and how will I know? I'm meant to be getting a lend of a mates coil 2morro to try it and see

beller

i just bought a secondhand distributor off ebay £30 delivered ish
you can get the sensor ebay again but for ease and price...

mk2grp1

hall senders are pricey and you have to strip your dizzy to fit them,
which can be awkward, used working dizzy`s are your best bet,
an auction website may have 1 ending soon

andrewmill

Yeah so that would stop the coil from getting a spark as we'll if this sensor was knackerd ? Ok I'll get myself a second hand dizzy but when you install a new dizzy do I need to mark where the bolt is on the old one in case I fuk the timing up?

andrewmill

I have a dizzy here it's on a xr3i head tho, are they the same?

beller

the coil doesnt get a spark, the coil releases the energy to give the spark i think its all about the coil getting negative earth from the signal generated by the hall sensor via the silver ecu which then fires the coil

mk2grp1

fit replacement as original is positioned, marker pen or something
cannot go too wrong as the drive is off centre, check new dizzy has a seal on it
or you will lose oil from the engine, try the part off your mate for peace of mind
an xr3i dizzy no good as its different

andrewmill

Is there a visual difference between xr3i and rs turbo dizzys I fitted the one I had on the xr3i cylinder head and it's sparking now but won't start
