I'm in the process of installing an sr20det into my 89 240sx. The problem I'm having is with the starter. I can't get it to engage. At first when I hooked up the harness and tried to start the car it would try to turn. Now, it won't do anything. I've checked all the fuses and relay's and can't find anything wrong. When I turn the ignition, I hear a click and that's it. I've checked the power wire to the starter and it's good. When I take a screwdriver and touch the power connection on the starter with the other wire it turns over, so that tells me there's nothing wrong with the starter. The only left that I can think of is a bad ignition switch. Anyone have any idea's or does this seem to be correct. Thanks for your help.
