Just finished installing the ms and got everything working and the car is now responding to tuning.

Now for the problems.
First of all I have a major fuel pressure issue. The return line to the FPR is to small causing back pressure on the rail and my FPR won't run at any less than 80 psi. Which is way to high and causes constant flooding. At present I have removed the FPR and we have the car running without one, which is only good for non-boost load. :(
Next, my coil pack is only working on one side, which means the car is only running on two cylinders. It was at the end of the day that this appeared so I am not sure why or what has happened to the coil pack.

Bahhh this is so frusterating!!
any ideas??
