New to message board. Whats UP??? I have a question for you guys. I was recently trying to install an MSD box. The first mistake was trying this without the plug and play harness from MSD. I decided to wait till I get the Harness and reconnected everything back to original. Car wont start. I think I burnt up the OPti-Spark some how. I have no power to the connector going into the coil amplifier and all fuses check O.K. Keep in mind that when I was installing the MSD the fuse for ignition (under the hood blew). I replaced it and it still wont fire. What am I not seeing?

Thanks

 

Check the fuse in the passenger compartment on the side of the dash on the driver's side...

 

I now believe that it is the coil. For some reason when cranking the engine I have power on all three wires at the dual plug connectors at the coil. The one white wire with the black stripe should be a negative. With power being on all three wires I am guessing that I have an internal short at the coil.(Pink and pink with black stripe and white with black stripe all have power when cranking)

 

pull the coil wire from the opti and check for spark when cranking... becarefull when doing this....

 

I pulled the coil wire from the Opti. Dead, no spark.
