126 no juice to coil?

[nicknocks]

My 126 420sel ('86) has always started instantly in the two years I've had it. Parked it 3 weeks ago (to go abroad) when it was running beautifully, came back yesterday and IT WOULDN'T FIRE UP - battery fine, turns over fine, fuel pump fine (at least I smell fuel after cranking it), air filter fine... RAC man sniffs around with his multimeter and says "no juice reaching the coil"... can anyone kindly suggest where I might start looking for the fault as i've never had to look this far into ignition circuitry

with thanks,

Nick

Wild stab in th dark here but would possible guess the ignition module has failed, it looks something like this http://cgi.ebay.co.uk/Mercedes-Benz...5385230QQcmdZViewItem?_trksid=p3286.m20.l1116

but I could be wrong, I take it you have put a spark plug on the king lead fromt he coil to see if its sparking at the coil?.

Thanks for link, and yes I've tested plug on king lead and it's not sparking on cranking.

Could it be your fuel pump ? Kickdown relay.

I've posted several things re my recent experiences with problem starting, and car dying on Dual Carrigeway. then briefly starting and stopping. Check my threads.

I'd check the Realy if I was you. What is the number on it as I've just bought a s/hand one from the States which is not for my car.
