98 Sportage Won't Start After Fuel Filter Change

[pjd]

I didn't "depressurize" the fuel system first, just disconnected the lines from the filter and let the excess run off. The new filter went on fine, but now the engine turns over but won't start. The manual said to pressurize the system by connecting two points in the data control block, then turn the ignition on for 10 seconds. I tried it several times, but no luck. I opened a hose on the air intake and sprayed starting fluid in. It started and ran for a couple minutes, but then stalled. More starting fluid only produced a backfire. Any ideas?

Not sure what happened, but I removed the new filter and put it back, and it started right up!
