i dont have a Hymer - but i wonder if your dad had installed a secret anti theft device ? he was full of tricks like that.....
Here it is, my first proper problem, and it's with my Father's Hymer. I need to get it started and unfortunately he didn't get time to tell me HOW.
I'm no mechanical idiot but I'm sure I'm missing something. It's been sat for 7 weeks now without being turned over. I've got jump leads on so there's loads of voltage but regardless of Choke position and fiddling with the throttle... letting it sit for a while... it just won't fire. After turning it over for a few seconds there is some smoke coming from the exhaust but that's it.
The only mystery is the red kill-switch in the attached photo (bottom left)... but that seems to link the leisure circuitry somehow.
It's a Ducato engine BTW.
Any suggestions gratefully received!

How about looking at the rotor arm in the distributor?
If there is smoke coming out of the exhaust then it is firing on the plugs , The picture looks like a petrol Talbot and if it is they are notorious for getting damp and also dislike too much choke , spray all the HT leads and undo the distributer also , give them a good spray with WD40 , then leave your choke in push the accelerator down to the floor and let it turn over for about 10 seconds , if it tries to start pull the choke out about half way and that should then start . Good luck
On those old diesels they had a selonoid on the side of the diesel pump, going to it is one wire that becomes live when the ignition is on, so your farther could well have cut into this somewhere to make a cheap simple immobiliser, either check this is going live when the ignition is turned on or put a live wire directly to it or listen to it whilst someone else turns the ignition on you will here it click, or you can also unscrew it and take the plunger out as a temporary measure, it just means that you would have to stall it to turn it off.
PS leave the choke pushed in as

I can't help with why its' not starting but my Hymer is diesel and has what looks like a choke. I truth I suspect it works more like a manual throttle and allows me to keep it on a high tick over until it has warmed up.
Thats all said mine is based on a Renault (it's actually an Eriba Jet), just thought this may be something similar.
