Well guys. I just rebuilt my y8 block with a z6 head. Using the y8 dizzy, but it won't spark and of the plugs. The connector from the car to the dizzy has current, so its not that. I checked inside the dizzy and everything is perfect. I'm so stumped. This is my last step to getting the car on the road again. Everything works it just won't create a spark. I know that the z6 head has a camshaft position sensor, whereas the y8 head has a crankcase position sensor. But I still should be getting a spark from at least one of the plugs. Please help guys I need this car to run.

 

yea i have the same problem but i did a mini to my ef obd0 to obd1 and bought a new dizzy still no spark but im getting power from the distributor ohh might want to check your thermostat ground

 

Remove the distributor cap and rotor but leave the distributor connector plugged in. Then check whether the voltage reaches the Blk/Yel wire attached to the coil and igniter unit.

If so, crank the engine for 30 seconds to see if a distributor sensor code is set.

If not, resistance test the coil and have the igniter unit tested.
