I have a 80 300D that is still having problems with a slight miss in what seems to be #2 hole.
Compression numbers look good but no matter what I try it doesn't seem to fix it.

I am now thinking it is the pump. I have access to a couple of pumps.
1 is off a 79 300D and the other is off an 85 300 Turbo.

What is the difference between a turbo and non-turbo pump and the injectors for these cars?

Physically the appearance of the 85 pump is a match as I believe it is a MW pump like mine. The 79 appears to have a M-RSF pump.

Could i use either of these as a test for my pump?
Could I exchange these injectors for testing also?

Thanks
