89 300CE 181K

I have occasional start problems. But it will always start after about 5 seconds of cranking with the accelerator about halfway down.


does your suggestion above mean that I have leaking injector(s)?

Thanks

Somewhere Merc says that 4-5 seconds cranking can be considered normal. If your injectors are 181K miles old, an improvement could probably be noticeable. Replaced ours at ~140K and warm starting improved to close to immediate with no open throttle.
