cant get it started!

get a test light and poke around. Put the clip on the battery ground and look for positive + voltage. I would first check to make sure that the coil + is getting power. Then check for power at the ballast resistor. Make sure to have the ignition key in the "on or run" position when poking for power.

Do the gauges get power when you turn the key to the on position inside?
