My S3 has a Cossie 24v conversion. I'm having trouble starting the car after it's been running. Doesn't seem like a fuel issue. Car doesn't turn over and no click from the starter. Immobiliser issue? Car always starts from cold and will eventually start if I leave it long enough. Any ideas? I'm thinking it's got to be electrical.

Always worth taking the steering cowling off and checking if it still has the infamous YELLOW CONNECTOR. If so then open it to see if it has fried inside.

Other issue which gives similar issue is a buggered starter or starter solenoid

My brother had this on his Chim and there is a kit to sort it out, have a look
On the chim site very common with them, something to do with power to the starter motor I think

Had this on my S2 a couple of years ago - was the starter.

Immobiliser and yellow connector worth checking though.

First of all, ensure that your starter & solenoid terminals are free from corrosion, clean & tight & coat them with vaseline. Same goes for your earth strap connections to the chassis.

Thanks guys, will check all of the above. How do I go about checking the immobiliser?

No idea frown Is your fuel pump priming? I think that's what they cut the power to.

My immobilizer isolates the starter solenoid. Being a hot start issue its more than likely the starter solenoid itself. Mine did this a couple of years ago refusing to start when hot. New solenoid about £30, bolts to top of starter.

Fuel pump priming. Start solenoid sounds a good bet Andy. I'll price it up.

Okay, checked the main connector block at the ignition and it's a bit frazzled inside. What do I replace it with?

Used male and female yellow crimps on mine. Rated at 48 amps which is 576 watts. Been ok for the last couple of years.

Crude, but it works.

Interesting topic.
When I removed the steering column to replace the bearing looking at the wiring there are a number of choc bloc connections on reasonably heavy white cables.
Not looked at a wiring diagram yet, but can anyone say that was from new? and any idea what the cables are
First thought was it was a botch job but maybe not ??

Choc block is OK for a temporary fix but has no real place on a vehicle wiring system. The original wiring connection to the back of the ignition switch had a now infamous inline “yellow “connector most of which have now failed and been replaced. And if anyone still has one that hasn’t failed, it will! it just a matter of time.

Picture of yellow connector


While I agree entirely that "Choc block" connectors are not generally for automotive use, in this particular application I think they are a good deal better than a poorly soldered or badly crimped connection scratchchin


Strip enough insulation and use a big enough block that the wires overlap, each screw tightening onto both wires.

Agree with Cap'n Bodge

Crimps are ok and actually pretty good provided you have a decent crimping tool (I.e. Not from Maplin)

The Choc blocks should work fine provided that you at least have a decent screwdriver to tighten them!

The starter is pretty easy to test, you could use a meter but the best way would be with something like a Gunsons remote start so that you rule out the other wiring (yellow connector or whatever). If you are feeling brave just use a piece of wire direct to the battery. This will only actually test the solenoid, but let's face it you should be able to see if the big wire from the starter to the battery is ok and if everything else works your earth wire should be ok too.

Good luck

Greg (sparkly)!

I still had the yellow connector which I believe is a Ford item and always fail. It was frazzled. Weird it wasn't replaced when everything else was? Anyway, I used yellow crimp connectors and then wrapped in plenty of insulating tape. Took the car for a good run and tried a number of hot starts and all seems well. Thanks for the help!!
