If nothing else was done besides heads. Make sure all your grounds and positive leads are hooked up. Check codes. You will have security codes or loss of data codes. Clear out and do security relearn procedure. You can you tube it if you need to or if you have Shipley or all data. You can do a maual relearn and it should start after relearn

Shopkey or alldata

It won't show any codes reads error

That's a good idea I can go on all data and check the wiring my grounds, I hope that's the problem but I did have a problem with the car not starting before it would say theft system problem three seconds to wait but it started after that and I think it was because of moisture and when it rained and maybe from it sitting It got worse I hope that's not the problem I hope it's just something like the ground


I had a 96 deville. The windshield leaked right on top of cluster and shorted out. I could get it to relearn but after about 20 min it would start acting stupid. Start running bad and gas door would open and trunk also and then shut off. Go not theft again

I think mine leaked in the same spot and the dealer said to start with the cluster. I just don't want to waste anymore money. PRD321 is what's flashing and I tried two code readers and nothing. My thing is it was working b4 all this but maybe it was a coincidence and my cluster is bad now from moisture
