Check your fuses and trace the wiring to be sure it isn't damaged or broken.
If you do not have one a Chiltons Manual with the wiring diagrams is a big help.

Checked fuses, wires look fine. I have manual book. Relay only has power at red wire. Do you know anything about saftey switch on clutch pedal.. Was told that can be a issue but how?

The safety switch on the clutch pedal just keeps you from starting the car without pushing in the pedal first.
Not sure how that could affect it, trace the wires out in the manual and see how they are connected.

Yes you can. If it doesn't let power through the contacts then likely the relay coil is burned out.
