wiring should always be the first thing you check, if you have a multimeter check that you have continuity to the correct pin on the ecu. If you don't have a multimeter...get one or at least one of those lights.

i have the voltage light i put it to the pressure switch wire while the car was on and it dint light up i put it on both wires and got nothing what could it b do i nee a new wire harness for my car

Don't use a test light for this. Use a multimeter to properly diagnose the problem.

As for the CEL, try resetting your ECU and see if the CEL goes away.
