lost crank signal chug: i'm using hp tuners software and a 2002 ls1 pcm, when i scan in real time there is no rpm signal. Naturally i changed the sensor still nothing. Replaced the wiring and ... nada. placed a led in the circuit and wala i get a pulse but no signal on the graph and no start. Step 2 changed the pcm with a ls1 2003 model and same issue. Does the theft deturant systen disable the crank signal? I'm new to this computer stuff so "dumb as a box of rocks" might apply... HELP !!!!! thanks:
ps: it was running..... go figure ...
