I presume there's still a relay there to do the actual job Ben?

[Mandrake]

I doubt whether a starter inhibit relay with burnt out contacts would log a fault on the display or Lexia, even on a C5...the starter will just fail to fire.

A few minutes with a wiring diagram and a multimeter in the fuse box should narrow down the cause of the problem, the inhibit relay can easily be bypassed, as well as checking for voltages coming from the ignition switch etc...

Just been looking at the wiring diagrams, and yep there's still a relay, it looks like the "selector lever position switch" is what the energisation of the relay is based on, and it seems the BSI uses the same position switch to display the message when a crank is attempted. So like Simon say, a burnt out relay would not be picked up in this situation.

David, did you get SEDRE installed in the end?

Exactly how the XM and Xantia does it then Except there's no BSI on either. Just a stony silence from the starter if you're in anything other than P or N I think the S2 Xantia may bleep at you...

Nope, just stony silence

Ben,

SEDRE has been nothing but a pain in the back side so far! So haven't got round to getting it up and running! Does anyone know where the starter inhibit relay is located?

Glovebox fusebox apparently, Marked 1005 in this diagram:

Thanks Ben, it doesn't have a wiring diagram for that relay does it? Be handy to know which pins to short out.

Here's the relevant bits (sedre is a pain in the ass to get a decent image from the whole diagram), wires with blue crosses go to BSI, the red cross one goes to the ignition.

Thanks Ben, really appreciate it.

No problem Let me know if you need any other diagrams.

Well I've found the relay, haven't checked what's going on yet though.

I've also found the reason there's no coolant in it, there is a hole in the bottom left corner of the radiator. I'm really hoping this is an age related hole caused by corrosion as it's sat still over the years and that it's not been driven with no coolant in it.

Hoping & Praying to god that this isn't the reason that it was laid up as I reckon the folks and my other half will go mental if I've got a V6 with a knackered head gasket

David, its very difficult to drive a c5 v6 without Coolant (well a low level at least) and not notice it, the computer goes nuts telling you to stop and top up the coolant every few minutes. (speaking from experience )
Unless of course that sensor was knackered for some reason.

Well after a couple of hours tinkering this afternoon, here's the results:



Firstly I got it on the ramp and took the arch liners out and turned the engine over by hand with a socket on the crank pulley to make sure it wasn't seized. After that I moved the gear lever in and out of drive whilst my dad had his fingers on the inhibit relay, he could feel and we could both hear it working. After this I took the connections off the starter motor and checked for 12v on the solenoid wire of the starter with a multi meter when someone turned the key. There was a nice healthy 12.5v down there so it was looking likely the fault was with the starter.

Took the old starter off and tested it with jump leads straight onto a spare battery and nothing happened. Anyhoo, I saw a starter motor on eBay last week for £20 delivered so bought it on the off chance, fitted this one to it, there was a few clicks from the solenoid, few beeps from the car, then it started. The solenoid didn't drop off straight away as you can hear in the video but she was purring on all 6 straight away.

I put some coolant in it and started it again, revved it gently to 3000rpm and it's running lovely. Unfortunately the coolant was pouring out as quickly as I could fill it so I'm on the hunt for a radiator and a back box for now.

Priorities are radiator, back box, timing belt change and rebuild the front brake calipers.

Bugger me!!

Just had a quick look... Part number for a rear section of the exhaust from Citroen is 1726RP. According to Citroen Service it comes in at a hefty £1094.81!!!!

Christ almighty... I'd expect two cars for that much!!
