My '82 300D has always been a good starter and has run beautifully till yesterday .
Yup , WON"T START .
OK , it was a little cold (-3deg) but that is not normally a problem , the engine turned over fast enough . Almost fired . Several times .
Then just nothing ,no fire , just revolutions on the starter . Finally drained the battery .
Got the battery recharged .
Took the Auxilary fuel filter off , just a little gritty stuff in the bottom of the bowl , nothing like the muck that was there when I changed the filters last month .
Bled the system .
Tried to start again , almost fired , but not quite .
It feels like no fuel , cracked the injector line at the #5 . Got fuel there cranking the starter .
I'm stumped .
Is there a filter in the lift pump ? maybe its got a blockage in the tank , oh dear , ok , so how do I get the tank out , its a W123 .
Maybe it just sucked some air in ,, but a bleed should get it restarted ?
Could it suck air and not leak fuel ?
I was told to check the glow plugs , shorted the hot line to the block with a screwdriver , got a spark at all 5 , that means they are all ok ,,right ? .
Hmmmm now the glow indicator on the dash is not working
,,,,
Please help
