i have a 97 z28 automatic all stock lt1. the other day i went to start my car for work and when i put the key in all my lights came on except for my odometer didnt light up. the security light comes on for about 5 seconds then shuts off which i think is normal and when i go to start the car nothing happens what so ever. the battery is good and i even go under it to cross over the starter and it will spin but never engage. i can here my fuel pump prime and everything. i have checked all my fuses and cables are tight. not sure if it could by my bcm, security of even my starter?

 

sounds like the problem I'm having please help

 

Same problem I am having to a friend of mines camaro did the same thing and he had to replace the PCM I have a spare PCM I'm gonna swap out tomorrow I'll let u know how it goes

 

There's no interface with the PCM for the starter circuits, only the BCM and theft deterent relay.

I have the same issue. I have a 02 Z28. It is totally random but I can turn the key and sometimes it starts with no issue and other times it might take 2 or 50 turns of the key to get the car to start. Everything turns on correctly and the security light does not flash so it is not a bad key..which has been replaced. I can hear the fuse on the hood spark and the fuel pump hiss and turn on but no ignition. I have swapped out the ignition fuse under the hood. Acutally there is times that the car will not cranck no matter what I do, but do to a fit of rage one day I knoecked the plastic cover off of the small square ignition fuse and if I stick a metal opject in there the car will turn over one and start everytime. I have swapped that fuse about 5 times. I can usally get the car to start but turn the key to the start position rapidally for a few seconds and it will eventually start. It is annoying as crap.. I love it when it is raining or 100 flippn degrees outside. Any thoughts?????
