I have no signal to fuel injector . Ground the hall effect switch get spark and fuel injector ! Changed everything under hood except ECM ! I get the prime squirt of gas but at cranking nothing ! ASD is good got power to fuel injector ! Checked wire on injector back to ECM good ! Checked wires from hall EFF. to computer good ! Got fuel presure ! Can soak a rag in gas throw on top of TBI and it will run as smooth as silk ! I just have no signsl to injector to pulse it !what dosnt make since is that if you ground hall effect that you get a spark and a pulse to injector but when you connect it back up and try to crank it you get the prime then nothing !!!

Learn the system ASD supplys the 12 volts ECM AKA computer then supplys ground to make it work ! So leaving it grounded would do what !!! LoL
