Hi get a length of wire and take it from the + of the battery and connect it to the solenoid on the side of the injector pump (the one in the 1st picture)........ hold your foot to the floor on the throttle and crank the engine it should start immediately,.... as soon as it starts ease off the throttle. If its working there will be quite a bit of black smoke when revved, then remove the wire and see if the smoke clears if it does then you have a wiring fault, if not the solenoid in the pump has failed.

Hello, thanks to everyone who replied especially Alfie your a top bloke who knows his stuff, wired from battery direct to solenoid heard it click and bingo started immediately so i assume there,s a break in the loom wire. Fitted isolator also so hope this stops the battery from going flat when stood regards keith.

Hi Again, No problem I am always glad to help, Dont leave the solenoid connected all the time though........ if I were you I would now take a lead from an ignition switched source... and put an isolator switch in the circuit and take it back to the solenoid, you can then switch the switch on in the cold weather and as soon as the engine is started turn it off. otherwise you will be using a lot of fuel if you leave the solenoid energised . Regards Alfie

Does the sensor on the thermostat housing not de-activate it when it warms up? because i havn,t bypassed it just replaced the live to it regards keith.

Hi Keith, Yes it does, sorry I thought you had just hardwired the solenoid valve...... good job mate but you really need to wire it to an ignition live rather than a permanent live. if you locate the reversing light switch on the drivers side tail of the gearbox, one side of this switch is an ignition switched live, just take a cable from this to where you put your permanent live that would save running cables from the cab Alfie.

Hi, As a new member I have been reading this thread to try to understand why my 811 first registered 1987 won't start from cold. It seems that the problem could simply be a blown fuse. I have no manual or instructions. Which fuse should I replace to try to solve my problem? Where are the fuses?

Hi and welcome,
To check the fuses on your Cargo they are located under the glove box there are 2 turnbuckles.......put a flatbaded screwdriver in the slot and 1/2 turn it and the panel should just pull off. please be aware that Cargo fuseboxes tend to melt underneath on the printed circuit so if you see any fuses and the plastic on them looks melted you will need to either get the fusebox re-conditioned of replace it.
Let me know how you get on.
Alf

Thank you. I've got to the fuses now but none of the symbols suggests a cold start. Do you know which fuse I should change to get the cold start solenoid to work?

Sorry I cant remember which one it is,........ if I were you I would just follow the instructions I posted above and rewire it ........as it usually is a wiring fault, you will probably find the fuses are all ok.

Hi, follow what alf has told you, its how i have wired mine, all my fuses where fine but no power to the solenoid.
I will just say change your filters air and diesel as you can get crap build up which doesnt help when starting cold, dont start trying easy start it doesnt work and all you will get is the bottom of the engine knocking like hell, and it seams to lock the engine up when turning it over.

Glad it worked for you as well James.........and I agree its VERY important to keep clean filters on these engines, also easy start is'nt the best product to use as it effectively washes the Carbon from behind the piston rings and you end up with an engine that burns oil until the rings Carbon back up. I can always remember in the old days Mechanics saying dont use that stuff as your engine will get addicted to it LOL, the reason they said this is that once the Carbon is washed off the compression drops and then it wont start without Easy Start. Have a good Xmas and a prosperous New Year Lads & Lassies. Alf

Thanks for all your advice. The temperature in Derbyshire is above freezing now though still nippy, and the Cargo starts fine without any of the cold starting routine that you have described. I just crank it with a tiny depression of the accelerator and she is away within a second or two. This has got me really confused: when is the cold starting routine (accelerator hard down) needed?

Hi glad its running ok now, I always start my Cargo with foot to the floor when cold, but lift off as it starts.
usually when the weather drops to freezing the cold start system should come into play as the sensor then passes full current.
Regards
Alf
