hey all i just bought a old mr30 skyline with a rb20det a few weeks ago. its a conversion with a supra gearbox t3 turbo with a big ass rear housing, front mount, external gate. boost tap, exhaust. its been driving fine untill up high no matter what the boost tap is set at the boost gauge is always pushing 14-16 psi and missfires. but last night i got in it turned the key the motor turns but wont start. i clutch started it and it ran fine then i turned the key off started it a minute later with the key it fired up, turned it back off waited ten minutes or so tried turning it again and wont start but the motor just keeps turning we checked the fuel line and im getting fuel past the fuel filter but beyond there i dont no. if anyone has any ideas on what it could be would greatly help im out of ideas. thanks all....
