i am not gettin a injector pulse to any of the 8 injectors. i checked all my fuse's all ok, i have spark. i have a cardone opti, msd coil, wires, plugs, battery i have read on many forums that pcm's are common for goin bad. i did a mild cam install this winter car ran great before my tear down.

 

what year and model/motor? so this all started after the tear down?

 

all 8 at the same time sounds like a pcm issue.

 

sry bout that i have a 94 z28 with the lt1 yea i did the tear down to install the new cam and when i put it back togetheir it wouldnt start i noticed i had no spark so i checked the opti and coil which solved that problem now im not gettin any injector pulse the car has 106,000 miles on her

 

are you sure you got the right cam for the opti and the right opti for the cam and timing gear. the pulse for the injectors is based on a pulse from the opti and/or coil. i would look there first.
