I'm having an intermittent problem with my '79 300D not completely starting which has increased in the last 2 days.
What's happening is that when I turn my key enough for the glow light to come on, it's not coming on at all. However, I'm waiting a minute or so for the car to "glow" even though the light is not coming on.
In the last two days, this "no glow" problem has happened once on BOTH days and I've had to spray starter fluid in the air intake for the car to completely start.
I have not had to spray starter fluid when the no glow problem has happened before - I just turned the key to the off position a couple of times and turned it back to the glow position, and the light glowed. I checked my glow plug fuse (the silver piece of metal) and it's in tact (I assume). I don't know a lot about that fuse, however.
This starting problem happens when my car has sat overnight for hours in my garage. The weather has NOT been cold here this weekend, just to mention. Also, after having this problem on Saturday, I plugged up my engine block heater Saturday night, while garaged, but this no glow/starting problem still happened on Sunday (today) when I tried starting the car. Again, I had to use starter fluid for it to completely turn over.
When I tried starting it without using starter fluid (and again, when the glow light did NOT come on), the car will make the sound like it wants to turn over and it sounds strong in doing it. It's just not completing some final step in starting.
Once the car HAS started, the engine runs rough & knocks a bit until I drive it awhile. After it's been driven awhile, the engine purrs and the glow light comes on most of the time after turning it off and starting it up again. There has been times that the glow light has NOT come on and the car starts fine, but that's after I've already driven it for that day.
I switched from the old style glow plugs to the new, fast-starting Bosch glow plugs last month. (I was having problems with needing to wait a LONG time for the car to glow and start before getting the new plugs). So, I'm stumped at this point.
Does anyone have any insight on my current starting problem?
Thanks...
