89 Jetta Engine in 88 Golf, Fuel pressure floods in instants

Okay I just recently inherited an 88 golf that has an engine from an 89 Jetta in it, and it's having fuel pressure problems. I've got the Digifant II fuel system, and it takes it all of about 10-20 secconds to fill the cylinders to the brim with gasoline which makes a hydralic lock that prevents the car from turning over. I noticed that there was a vaccum leak after the temp. sensor in the intake, and after clogging that the problem wouldn't go away, it still fills the cylinders before it can start itself. The guy I got it from thinks that it's a computer problem, but I'm wondering if it's just the fuel pressure regulator that would have raised the fuel pressure with that vaccum leak. Anybody have some advice?

ok, I changed out the computer and that fixed that problem. Now I can hear that the fuel pump is operating as it should, but the car still won't start. My spark plugs are working and it turns over fine, but I don't think it's getting any gas. I have a feeling that it could be a problem with the Hall Sender, but I'm not sure if the presence of spark rules that out or not. Somebody else told me that it could be an injector problem, and that maybe the injectors are not getting voltage, is that a possibility? Please somebody, I need some ideas.

Thanks,
Rick
