W460 280Ge turning over but won't start
Hi!
Long time since i've been on here but back as need the big brains help please
Quick rundown:
- Car stood for about 2 years with no starting
- Got a new battery
- Had a minor fuel leak on a hose near the fuel pump that went up to a weird device above it and the towards the engine
- Replaced hose matched lengths etc
- Car now turning over without a leak and twice has sounded like its almost taken and engine started but now it just continues to turn over but nothing else (fuel pump makes that classic veeeeeer sound when ignition on)
- Put in new spark plugs but still only turning over
Will say not 100% mechanically minded but can figure stuff out with guidance.
I'm wondering if it could be air in the fuel line but not sure how to remove that if its not that not sure on the next step to take
Any advice would be really apprecaited
Thanks for everyones help over the years

Good to see you back Joe.
(its a bit quiet on here ot the moment, and the old website is creaking, but hanging in there)
Get a can of easy start. Take the air box of the top of the fuel distributor and give a good squirt directly into the cylinders - this should get the engine firing and prove you have spark. The extract oomph may drag some real fuel through and keep it going.
I have a 230GE with the same issue after 2 years and was told the old fuel in the pipes may have jellified. I suppose you can tell that if you remove the feed to the fuel distributor and check there is fuel pumped through to there. If so, the smaller pipes in the distributor itself - that would be a pain, so hopefully the easy start will work.
The funny can-like device after the fuel pumps is an Accumulator. It is supposed to hold fuel line pressure, but they can jam up. Cheap and good to replace every 10 years. You should have 2 fuel pumps on a 280. I think only one Accumulator.
Reseat your HT leads to the plugs. whizz a small dose of WD40 into the actual mechanical Distributor and Rotor arm.
Thats about the extent of my (old) experience as I haven't had to worry too much about it in recent years.
Have you put fresh petrol in?
I doubt he has. I didn't either. Does Petrol go off that much??
What's the procedure for refreshing/replacing it? Syphon out the old? Or mess with the drainplug on the tank?
Depending on how much petrol in there? Could just add a few litres of fresh, sure there is a drain plug on the tank? Tho possibly may introduce problems, you read bad things about E10 petrol causing issues
Yes... its a big hole and should gush out!
I think you can confidently say what the issue is! That tank will need to be dropped and either flushed out, or replaced with a refurb one, or plastic if you can get one.
The 2 tank retaining straps can be fettled or get new.
Probably the fuel Fuel Accumulator is gummed up too and worth replacement.
You want to go to the Members Section and check out the manuals and guides there.
You are a Member to Jan 2025 and I added 3 months to it to try to get your Red Badge to appear - don't know why not. So I added a simple Member image for you, in case it was that, but no change - you can remove it if you like.

There is a guide on Fuel Tank replacement there.
Thanks for the quick reply Jdring! Really appreciate it
I will give the easy start a go so fingers crossed its just that! I will also do the WD40 trick! The Gwagon is an olden so not surprised it has some issues starting, Can't really complain as its been in our family since 1990 and has never let us down so theres always a first !
Thanks again for your help and I'll be back to let you know the outcome!
