Answer
Hi Justtin.
do a google search for that engine to see if you can find a wiring diagram for that engine and the ignition module. My guess is you missing a ground to the module or power. there are a couple of grounds that go on the bracket under the ignition module maybe you forgot to put one of them back on or when you tughtened it up the eyelet ripped off the ground wire. you could have pinched a harness and blown a fuse to the module. the module send an RPM signal to the engine cmputer to start fuel delivery. good luck :)
