If you will go ahead and install the ENTIRE fastglow kit correctly, you will be thrilled with the way it works and the car starts.
Anything less and you should put the loop type glow plugs back in.
There is no way to know what the system is supposed to be doing with half one type and half another.
The other thing that makes a world of difference with the 115 240 is making sure you have the biggest and best battery that will fit the tray, a weak battery will make trouble shooting very confusing.

I had not read the last conversation with whunter when I wrote this so carry on.
