Hi, ive got a series 2 rst. About 2 weeks ago just before the cold weather and snow came, i was driving along and the car jaulted, i didnt take much notice of it until about 4mins later when the car cut out, it took me and my mate about 10mins to start it. I drove a further 5mins and it cut out but started straight away, then i drove 30secs till it cut out again and finally wouldnt start, by this time i had mates who own cossies and esrt looking at it and they didnt know, finally 20mins later i got it going and drover to a mates house and left it there overnight. The next day it wouldnt start so i put a group A coil on it and it was fine for the night until i decided to go for a drive with friends. i was on full boost and there was a massive bang and then it cut out again. we found that there was an earth wire by the rad that had split, we twizzled it together and it worked again, so i drove home and left it overnight. the next mornign my car struggled to start, finally after 7/8 seconds of turning over it started, i thought it was just the cold weather over night that had made it struggle. I drove to work and tried to start it at the end of the day but it wouldnt start. i left it there and came back the next day and tried again but still nothing.

I got a couple of mates who have owned rst's in the past to look at it but they couldnt work it out. so i got a new dizzy and fitted it and still nothing. Since then we have narrowed it down to there being no feed to the coil?? There is no spark from the lead that goes to the dizzy. ive tried a motorsport racing lead on it and still nothing.

I'm offically stuck, i didnt want to take it to a garage but i think ill have to unless someone on here can advise anything??

Thanks alot, Joe.

 

You should have +12V to the black wire at the coil with ignition ON. The green wire is switched (Which also feeds rev counter) So does the rev counter move do anything when you turn it over?

It's not uncommon on RST'S for the green wire to break, so check this for continuity, thirdly I believe the RST uses a Transistor based module on the dizzy for the ignition timing, I may be wrong but if it does it will be fixed to the outer body of the dizzy with it's associated connector, these are known for failure.

as above, the black plug on the top of the dizzy become loose, it causes the wires to touch the spinning internals, wear through an short out, if u have not checked this i would be pretty sure its your problem

 

Ok ill check the voltages and that later and let you know.

Ive changed the dizzy since it started because the wires in it where worn from the internals and still nothing, the black thing on top was lose on the old one but its not now.

Am i right in saying the earth that goes from the coil and passes by the radiator, goes to the ECU? I cant trace where it goes because it goes into the rest of the loom by the fuse box.

Thanks for all the help.

 

I had a prob just like this matey

If the black switched live is fine and stayes fine when turning over then start on the green side this runs in the loom along front panel and up to ECU which it also feeds back out to the rev counter i was hoping i would find the prob in this trusty green cable but was fine

In the end i changed the dizzy and was taken from a car i had seen running with my own eyes and bolted it on and BINGO was fine and still is

The ignition system on these and fuel system is gay and belive the EFI convershion is the way forward

 

Yeah its a pain really.

Ive got it at a garage now so im just waiting for them to open again and have a look at the car and let them solve the problem..Im getting Omex for it anyway just need to save up some cash before!!

Ill let you know what was wrong when i find out from the garage.

Thanks for all the help people!

 

Bad news,

Its been in a garage for a week now and they traced it back through the wires and where 99% sure it was the ecu, so i got a different ecu and they tried it and still nothing. They are slightly confused as to what it is, Apparently there isnt fuel getting to it anymore.

Is there anything that would have an effect on the fuel and spark together or would it be 2 different problems? Maybe the immoberliser? I dont know where the immoberliser is connected to though, not sure how to find out either.

Thanks.

 

Not so far as I know, I believe the inductive pickup sends the signal to the ECU, the pump runs off the ignition pulses so unless you have spark, the fuel pump will not run.
