I changed my opti-crap a few months ago and now when I go to start the motor the voltage drops into the low range and the car barely runs with the gas petal to the floor. It`s as if I have something draining the volts when I start it. I have replaced the battery,coil,ignition coil module,the wireing harness that plugs into the opti-crap and even taken the opti off and replacing it with another new one with the same results. I have checked the positive wire plastic housing mounted on the pass. side wheel well along with the ground wires located in the same area. I`ve checked and double checked my plug wires and any other electrcal wires around the opti-crap area. All of my ground wires are bolted on the coil bracket. I also took my alternator off and had it checked. Help me if you can, I miss my 6-speed LT-1.

 

what voltage is dropping? the cars voltage(low 12-15) or the ignition voltage (40k) ?

 

car voltage

 

is the starter hanging up?

 

The starter kicks right off when it is suppose to. The car just barely runs and it seems like the injectors are not getting enough volts? My volts drop when I start it.

 

have you also checked your fuses yet? I think you guys have a charging fuse in there. Mainly just bumping this back up for you

 

I`ve checked all my fuses over and over again. Time for me to go to work. Thanks, any other ideas and I will check back tonight at 3:30 when I get off tonight.
