What is this pressure switch for? 200 84

posted by  someone claiming to be Jessie on  Fri Nov 9 14:32 CST 2001 [RELATED]

It's an intercooled kjet turbo. There is a pressure switch just behind the fuel air metering unit. It is connected with the pressure line that goes to the waste gate. Can anyone tell me what this switch does? I can't find it in the haynes diagrams anywhere. Took my car for a test drive today and something is cutting off my fuel injection when the manifold pressure gets to atmospheric. So I want to check the function of the pressure switches. I have replaced all of the leaky vacume lines, so I am hoping its just one of these switches overreacting.
