Looks like you might be doing things on the fly.  That doesn't work well for the fuel injected cars.  Download the Factory Service Manual and Turbo Supplement and get things set to specification.  Fuel pressure is measured in psi, and yours is waaayy high.

Have the new injectors been sitting installed in the car for the 3 years?

Time to methodically go thru the EFI bible troubleshooting guide.
