My car knocked the block and I changed the block I used the Monza block with the Astra cranck sensor blade. At first it was promising to start, but suddenly there was no more spark. We changed the crank sensor and coil pack, but still no spark. Tested the computer box with onother car it works. But on my car still I cannot find spark. What else needs to be checked? Please help I love my car very much. Thanks

Hey MSICO,

I would start by rechecking all engine grounds and engine to chassis ground which is super important.

Does the security light flash on the dash when you are trying to start it?

Please let me know

Best, Ken.

Okay, the security system in enabled, please exit the car and lock all doors, let the car sit for 30 minutes and then unlock the drivers door with the key and recheck.
