w126 cuts out after ignition...

[monkeyson]

Hi all

Can anyone help please?

I tried to start my w126 420 sel this morning and although it turned over adn "caught", the engine then cut out immediately before I could rev it or change gear or anything.

I've had the car for 8 months now, trouble free, and it had a full service a month ago.

Any ideas would be much appreciated.

Many thanks

With all of this rain and damp weather, I would check the dizzy cap and rotor arm for tracking

Thanks will do.

Seem to remember garage mentioned dizzy cap screws rusted in. Getting the feeling this might hurt...

Or the fuel pump relay.

Or the ballast resistor

Dont think this one has a ballast as its a 420. Could be wrong.

The fuel pump relay can be dodgy take it out and bridge pins 7 and 8 and see in it keeps running

I fixed 2 last month
