2002 Saab 9 3 Died On Freeway Last Week Took Into Shop They Told Would 1000

My Saab died on the freeway last week. I took it into the shop and they told me it would be $1000 to replace the fuel pump so I took it home and did it myself. Before I did it would start for about 30 - 90 seconds and then die again. Now, after replacing the pump it will not start. It appears as if I am getting fuel to the rail.
