Forgive me if ive missed the answer on previous threads, im still still a bit stuck (im simple)

My disco (97 300Tdi) has been stood for a while (clutch broke) abd the cold weather conpletley drained the batt. Took it off for a few days to charge. Now key fob unlocks doors ok, get in cranks over but alarm goes off upon cranking starter...

Disconnect alarm siren try cranking, turns over fine but wont start, like no fuels getting in...

After a bit of reading I think perhaps spider thingy is playing up not allowing current thriugh to stop solenoid.
This is where I get stuck, was going to test to see if current at stop solenoid and also try bypassing it with a permanent live to make sure solenoid is the problem.

Simple me cant find the solenoid or wire/connector for it (pics of pump attatched.

(Just to add I have no spare key fob, dont know the EKA code, and the obly key I have disnt fit the drivers door lock....the list of jobs just to get my disco back on the road and reliable seems to be getting out of control!



Any help thankfully received

Sierraferry helped me diagnosing my starting problem. I had a smila issue.

in my case it turned out to be the crank sensor. Yours might be another issue but Sierraferry was very methodical and it excluded a few things before I started replacing stuff

Thanks, as mine is the 300Tdi however different circuits,ecu's ect.

Anyway after a bit more reading I now know My car has the DDC immobilisation fitted, hence I couldnt find the diesel stop solenoid, as its hidden behind the black anti tamper DDC thingy. Now I can remove that and see if the stop solenoid is or is not being powered with ignition on.

However if that is the problem and I bypass it with a ignition fed live directly, I will then have no working immobiliser or alarm.

On Disco's with DDC fitted I believe there is no spider behind the centre console (so cant bypass to give me a working alarm but bypass imobiliser.
Is the alarm/immobiliser built into the main ECU on these vehicles or is it seperate?

Alarm, immobiliser are separate circuits.

So remove the protective cover on the pump and install a single wire from the fuse box at the point where the three ignition switch wires plug in, white, red, yellow IIRC, whatever the colour is you require the wire for position two, so just remove the existing wire and tape it up securely.
You may even be able to leave that wire in situ try it and see. There are threads already to tell u which wire your dealing with at the stop solenoid.
