Help! Could my problem be the fuel pressure regulator?

[Minitrax23]

Hi,

I just purchased a 1984 944, that I would like to bring back to life. One of the major problems I am having is turning it on. If you try to start it the engine turns but does not ignite. I was told that it was not building pressure and that if you turn the key 3/4 way several times rapidley, and then all the way it would start. Well it works if you do that. She will start that way and stay on, so is it true could this be my pressure regulator? Do I also need to replace the diaphram damper as well? Please help, what could this be? Fuel Filter?

It could be the regulator or a few other things like the fuel pump check valve. You have a regulator and a fuel dampener on the fuel rail. You really need to test the system pressure and volume then determine where it's leaking down. I have also seen fuel lines damaged from the vehicle being set up incorrectly on a lift.

Sorry, I was refering to the key in the ignition.
