no spark

At first I had spark from the coil only once every time i cranked. then i took an old crusty ecu and hooked it up and used some gator clips to ground it, had multiple sparks when cranking so I ran a ground the the orange box on the car and it seemed to give multiple sparks when cranking. then i hooked the fuel supply up and tried to start the car and had no spark. then I swapped the orange box out for the crusty box and still no spark.:banghead:

Is it possible I have enough juice to crank but not enough to run the computer???
