Yes, it is on the W123.......sorry about that. It has a newer glow plug relay.....replaced it last year with one that has the afterglow feature. I have the black hand primer pump. Reamed out the glow plugs and did NOT use antisieze at all.

I'll double check all banjo fittings and connections and also current test the glow plugs. Probably be on the weekend as I still have to use the car.

Please keep the suggestions coming as I want to nail this down.

Thanks,

Glenn
