Boost gauge showing zero

Boost gauge showing zero
Hi, I recently installed a td04h-15g greddy turbo on my 94 del sol and when taking it for a test drive im not showing any boost on my boost gauge. First thing i checked was for a kink in any of the lines and got nothing. The line is tee'd into the line from the turbo nipple to the wastegate actuator. I took the gauge line off and blew into it while my cousin watched the gauge and it showed 5psi. After this i started checking for leaks in all my piping and checked all couplings were tight. Does anyone have anymore ideas of what I should try?

Re: Boost gauge showing zero
You can find a manifold vacuum source easily. as stated about just T off fuel pressure line. Also Can you here the turbo spooling? And as said before. check all your lines. Make sure there tight and sealed. you might not think you have a leak but if the turbo is working but no boost. then you have a leak. It's a easy fix. GL

check all the wg lines and make sure there is no boost leak on any of the couplers. also if the gauge shows vacuum and then when you get on it and it only goes to 0 make sure there is no exhaust leak before the turbo and that the wg is functioning properly.

Re: Boost gauge showing zero
Do you have your down pipe connected? All exhaust gaskets installed? Does it read vacume at idle? Any loose couplers? And you have great lungs blowing 5psi lol i kid I kid
