Hi everyone

New to G Wagons just got my self a 1989 230ge as a non runner that just won't start but I will get there with some help I hope:)

I was into series land rovers for years but always wanted a G wagon - can't wait to get her on the road.

So far I have done new plugs,ht leads,dizzy cap and rotor,ignition coil,fuel pump and filter,oil filter and just put a new water pump becuse it was leaking and finally thermostat.

So I think I'm going to have quite a few questions along my G wagon journey:) Oh the paper work I got with my "G" the previous owner was a member also.

Thanks and a great to be part of the club..

Re: Newbie

Welcome and thanks for the membership.

You should get a fair bit of help here, and on the forum.  There are a few other groups for G- Wagen also... its a fairly small community.

Well done with the work so far.  In the end they are MB engines and many parts are the same, but you get to know the G specific bits.

For the 230GE, assuming you have spark and compression, it will be the kJetronic fuel delivery.  Make sure you have pressure from the electric fuel pump (under, to the front of the fuel tank), and a working 'accumulator' next to it.  Then the kJet works on vacuum pressure - if you have a leak in the pipes, the distribution and delivery of fuel will be out.  Best to assume the injectors themselves are good enough for now.  There is a black rubber connecting vacuum pipe under the air box which often splits causing problems... glue and tape it up(!) until you can renew it. 

And post a pic if you can work out how to add one to a post (see Choose File).  Well done not posting multiples on your first post, which generally takes about 1minute with no sign it is working.

Re: Newbie

Ok That's the fuel pump, fuel filter and fuel accumulator done! Still not starting 

She's wanting to start there is fuel presure there is spark. When trying to start she give a kind of back pressure noise out of the air intake with a wee bit of smoke.

Any help would be so apprecated just want to hear her run and leave me with some hair not much left to pull.

Thanks

Re: Newbie

 

Has she been stood for a while?

M102 seem to be prone to sticking exhaust vales when stood for a good while

The 4 pot engine can't cope with the lack of compression 

Often shows up with a puff of grey smoke that looks like steam even if it starts and runs lumpy will smoke and smell terribly 

Simple compression test should show it up

Re: Newbie

Ok - no sticking valve so checked the timing and it was way out think the previous owner took the distributor out for some reason and moved the rotor arm. Starts now but only runs for a few seconds.

The fuel pump primes then turns of when the engine starts. Is this how it works goes on and off when needed?

She will run continue with easystart sprayed in the air intake. ( she sounds sweet )

Any help please.

Re: Newbie

Or is it a failing fuel pump relay?

Doubt it. Pump runs, gets to pressure and stops. That's normal.  It will/should run again, and it is new so pressure should be sufficient (that's important).  This sounds like kJetronic control issue to me.  I had starting issues (ran fine once started) and had to take it to a KJet knowledgable mechanic in Reading (mainly just because they had the emmissions gear).  At the moment mine runs well but very rich and excessive CO, so I need to revisit it and probably change the injectors next.

The 230/280 KJetronic is mostly all self managing.  There are no real adjustments you can make manually, but there is one really sensitive one on the top of the fuel distributor which is the IDLE mixture which adjusts the position of the air intake plate to get the idle mixture right.  The system takes care of mixture when throttle is opened.

There is also a Warm up Regulator, (WUR), and other bits...Control Pressure Regular

Take a look at my saga here:  http://www.gwoa.co.uk/content/230ge-engine-stutter-misfire-jetronic 

because there are some good tuning reference guides there, like this one:

https://tasteslikepetrol.net/2020/02/bosch-k-jetronic-basics/

It explains what and how to test.

Re: Newbie

Hi all when Iturn the key i hear the pump prime for 3 seconds but when i crank her over the pump switches of is this a problem with the relay? Just can't get my head round when the relay powers the pump to prime but cuts of when trying to start.
