I hooked up a repaired MPEM back into my 1996 Sea Doo GTI yesterday. It is running great. However, when I put the key in it is not beeping twice and it is registering that I have no fuel in the ski. I know there is at least a 1/2 tank. Did I maybe connect wires too loosely when I was plugging up wires? Any thoughts would be greatly appreciated! Thanks!
