Strange starter issue????

Hello,

My 76 450slc usually starts with no problem from cold start. However, there are occassions where it won't start initially, then when I try to start again
immediately there's nothing. If I wait a few minutes (approx. 2-3) it will start. Has anyone ever experience this and if so what was the fix?

Thanks,
Troy

The cold start valve explains the easy cold start - It makes the mixture richer for the cold start.

The warm and hot starts are most probaply with poor/weak mixtures. Check air leaks and if not any check the air measure plate home and basic positions. If air plate has too much free play it does not press the FD plunger before strong engine running.

So did I. Maybe a ring gear or solenoid issue.
Not too clear on the problem.

I will do some more testing on this issue and try to give a better description of the problem. Just installed new plugs, wires, filter, and distributor cap. I will see if this helps.

So how did you solve the problem? I had a scare when I stopped for a snack and the starter just clicked. Any ideas?

Just clicked?

Did it eventually start?

Bad ground
Bad battery
Bad solenoid

My starter issue was due to the nuts on the starter not tightened properly.
Once we tightened the starter and the solenoid nuts all was well. I hope your
problem is as simple as that.

Yes, sometime I turn the key and nothing at first, put a charger on to top off the battery. Still the same.

The hardest part is figuring it out. Perhaps not with a starter ,it seems pretty difficult to get to.
