How do i make the fuel cut off switch so i can fix the flooding problem???

 

Don't worry about the guage, it sucks (get an aftermarket one). More of a worry is that if the gauge isn't working, the manifold pressure sensor (which provides engine load info to the ECU as well as run the boost gauge) may not be working. It's important, check it out.
As for the fuel pump switch, under the steering column is a big black relay with a yellow 6-pin plug. You can't miss it, it's the only yellow plug down there. There is only 5 wires going into the plug, the middle row is missing one. The the single wire in this middle row (black with white stripe) is the one you want. Cut it and wire your switch into it.

 

Check to make sure the pressure sensor is plugged in. Does the gauge come up to the 0 when the key is switched on?
