wont start, and stalls
 

so i posted before about doing a crossover tube job, (crack pipe) and how it didnt want to start. (reference the "timing issues" thread) i took everything apart again, couldnt find anything wrong, put it all back together, and the bastard started. after getting the coolant in it, and makeing sure their were not any bubbles, i took it for a drive to make sure everything was good.

now it was idleing perfectly for about half an hour, i took off, got about 1 mile, and it starts to shut down and back fire on me. after that, when i would try to start it, it would crank but not start, and i have a good amount of back firing. the epc light is on, although i have know idea what that light means.

anyone know what it might be? fuel pump? bad ignition modual? anyone know what the epc light is? any help from here would be greatly appreciated.

thanks guys, i know you'll come through!
