Question about 1989 Porsche 911 Turbo
It fires fore a few seconds then stops,as if the fuel pumps aernt running.normally you can hear the front pump but not now so ive changed this and no change,if you push the air intake flap down the system charges and fuel pressure builds again only to repeat the same thing when you try and start???????? any ideas
Try changing your fuel pump relay.

These cars use CIS injection with several mechanical pressure controls that would be effected by old fuel. I agree that the injectors will need a cleaning at a minimum. Bosch has a cheap manual for CIS systems available online that will give you a better understanding of the system. If you are planning on working on this system yourself I would highly recomend getting a fuel pressure guage tester kit for CIS from a supplier like Pelican Parts and do your research.

I would go through your connections..but definetly get the injectors cleaned and new fuel filters...the fact that its been "stored" is never good news for the fuel system....hopefully its been run frequently during this time
