SR20 starts but doesnt run.

well i got a problem with my car, it will start and will not stay running, i checked my ecu and it was flashing the maf, so i borrowed a friends and the car still started but didnt run. We even re-soldered the clip in just to make sure we had a good connection. We then decided to check for a vaccum leak and couldnt find one, hooked up a guage and got 15-16 in.Hg which is alright. Also we noticed the feul pressure was pretty high, approx. 45 to 50 psi, where the day before when the car was running was 39 psi. when we adjusted the feul pressure reg we could not get it to go down ( fpg is only one month old). Well im stumped and thought id try and see if anyone has seen this problem before. If you have any ideas of what could be causing this post me a msg and thanks for the help!

timing out?
