rough idle very lean sr20det

My sr20det sprang a leak on the oil feed to the turbo. The car was running fine before this.  I got the car home.  I replaced the line.  During the installation i removed the intercooler piping from the hot side to get the lines on.  I took the car for a drive, everything seemed fine.  A few days later i tried to take the car for a drive and it hesitate and shook the car.  I was also not building boost.  I got the car home and removed the intercooler piping thinking it was a leak.  I very carefully replaced the the piping.  The car will now barely start. It will have a very rough idle for a few seconds and then shut off.  During the idle the Afr is 16 or 17.  I disconnected the MAF. It made no difference.  I noticed the fuel pressure was dropping as well. I removed the vacuum line to the fpr and had a steady fuel pressure of 43psi.    Any ideas . Thanks
