[shiftdrift944]

as i have posted on another thread 944 only runs on 2 cylinders!! help!!
after replacing the crankshaft sensors(both) i wasn't receiving fuel to the rail so i first jumped the relay and it got fuel to the rail... then i tried to started and it started several times... then since i knew it was either the sensor not gap right or the relay. so insert the old relay i had on it and gave a try and it turn on normally.

till i go back the next day and try to start it and nothin? this is with the old relay... so i tried with the (new) relay i bought a few months ago... and nothing... and for also when im turning the key and as soon i release it would start and everything but it runs for like 30 sec. and dies? could this first be either the fuel pressure regulator? or the computer itself?
