Starting car from starter relay

Like the title says I can't start the car under the hood using a jumper wire at the starter relay. Over the years I've been able to do this with no problems, but have probably not done it in a couple of years. I had my engine out this winter and was trying to get it started at the relay but no success. Using the ignition switch to start it works fine. Last year changed the wiring to MAD ELECTRICAL update with fuseible wire links drove all summer no problems. Something to note this spring when trying to start from the relay I did accidently ground the jumper wire to the header for a brief moment which did spark. Car still starts from the ignition switch just not at the relay. I did swap the relay for a new one and still no luck. What do you think? Jayson
