im having problems with my car not starting. i put a new head on probaly a week ago and it started right up. the car wasnt running right due to a bad ecu, threw another ecu in and now that car wont start. cap looks fine and so does the rotor. it starts for a second then kinda stalls out..could it be the dizzy? because the timing seems to be on.

 

she just started up for bout 5 seconds then stalled out

 

Are you sure the new ecu is working correctly? Is it stock?

 

i tryed a chipped p28,stock ls, and a p30 and all did the same thing. i check the spark and it was weak it balry sparked
