You could be right but before going to all that trouble of replacing the intake gasket take a close look at the MAF (Mass Air Flow) sensor. Also look for a vacuum leak downstream of the MAF sensor. The MAF sensor may be dirty especially if you are using an "oiled" air filter and it was over oiled. Remove the MAF sensor and clean it with electronic cleaner. Make sure it is dry before reinstalling. If it is damaged, replace it. Also replace the fuel filter as a partially clogged filter has been know to set this code on some vehicles. Check all vacuum hoses and replace as necessary.

The 6 cyclinder motor has 6 fuel injectors. If your not getting pulse Electrical grond to an injector wire theirs a likly chance your not getting it at another. If your getting no pulse at all the engine won't run. Does the check engine light on with the engine running? What meadod did you determine that it had no pulse? Remove one injector wire one at a time with the engine running? If it's not running at all then the no pulse can be a common system part like the crank senser. Does the engine get spark? Most of the time pulse and spark are hand in hand so if the crank senser were bad it's not going to have s[ark either.

The fuel pressure has to to 35 to 45 psi. And no low fuel pressure will not cause no injector pulse.The veicle sounds more like a idle air control problem why? because as you stated it runs rough when it does start.Get it to start sysle the key you will hear the fuel pump go on cycle it three times then start it up. when the vehicle warms up take the idle air valve out and clean it with carburator cleaner or even brake cleaner you may even want to do the throttle body itself this should help with the hard start up and rough running
