Starting Problems
I have a 1999 G 500, which is having intermittent start up problems, it's starts sometimes but at other times its like i forgotten to put my foot on the brake, any idea why this may be happening?
Thanks in advance
Freddie
Hi Freddie
Could do with PM with VIN / REG to help more
M113 occasionally suffer with Crank Position Sensor issues that could show like that
Really need some more info on the car to guide better

Please see my Vin number below for the G wagen
OK I will look and come up with some options as I am sure others will also
Out of interest does it get used much or stand for periods of time?
Does it do the non start everytime or just occasionally?
When it does it next will you move the shifter from "P" to "N" and see if it goes in Neutral

Starter motor relay or starter motor!
or simply could be the key/Barrel needs replacing
Hi Gav
Out of interest does it get used much or stand for periods of time? Yes it often stands for long periods
Does it do the non start everytime or just occasionally? The problem started last week and the G is still starting
When it does it next will you move the shifter from "P" to "N" and see if it goes in Neutral Will do
Thanks Freddie
Hi Gav
I treid to start the car in P with no luck i moved it to N and it started straight away
Thanks

the issue most likely is the key, if it does not talk to the car then the car does not start; do you still have the second key? if you have an infrared key (and the model year points that way) then this is a tricky issue as Mercedes does not have replacement keys any more but in the past these have become available from time to time; there are specialists who are able to get these keys working again.
Maybe but electronics either work or they don't.
I was thinking its related to the micro-scwich detecting if you are in Park or Neutral. If it thinks you are in Drive, no start. Happened to me in a 460 automatic. Give that switch an overhaul. In a 460 its just under the gate-guide. Not sure on a 463.
I had that issue on a R129 in Germany, it got progressively worse. If the key does not work properly the immobilizer remains active.
According to the MB tech it's the ignition switch, lets see a new one has been ordered.
Thanks

If that is the case you usually don't get any dash lights come on for a non start but normal when it does... have you seen this?
The lights all act as normal on non start up, the tech is saying now it may possible be the starter motor as well.
try the second key, if this causes no problems you know the issue is the first key.
Theo has a good shout there
Very doubtful starter motor
More chance the inhibitor switch that stops you starting it in gear .. sometimes called the starter lock out switch
Located on side of auto box from memory
Thanks for the suggestions, i'll keep you updated next week once i hear back from the tech
