On friday I was driving to my girlfriend's house and the GN died on me at a red light. It was a pretty warm day and the temp gauge was at 200. After 2-3 minutes it cranked up but acted as if it was running out of fuel so i idled into a parking lot. I popped the hood and the fuel pressure was at 20psi with the line on and droping slowly. I turned it off, let it sit for 3 hours and tried it again and it ran fine, good pressure, etc. Yesterday I was thinking about racing but wanted to check the fuel pressure first. It was about 40 psi with the line on. I went to test it and fuel pressure decreased with a little boost so i let out. I took the vaccuum hose off of the regualtor and did a short test run again. IT was at 42psi when i drove to my little test area, fuel pressure dropped and varied between 38-32 when i got on it a little( <5psi of boost) so i let out again. By the time i got back from the test run(total travel distance of maybe a mile or 1.5 miles) the fuel pressure was down to 28psi at idle with the line off. I'm leaning towards a fualty fuel pump. Any other opinions?
