First 4th gen HELP Hello Everyone I hope everyone is having a great weekend I just bought my first 4th gen firebird. I have a 2nd gen i have had for 30 years and a 3rd gen i have owned for 15 but I bought a 4th gen yesterday 1996 formula lt1 automatic drove it 3 hours home ran perfect. the next day i stopped at the gas station filled it up and it right after i left the gas station it died smells of fuel and wont start. I waited 3 hours for it to start and run and then drove it home. I replaced the charcoal canister, the Vapor Canister Purge Valve, the evap Purge Valve, the gas cap, and also a few of the rubber purge lines that were dry rotted. Still having the same issue i have no codes but it is still dying after driving it for 15 minutes or so and it smells like fuel like bad. Any help any one can offer is apricated I am not vary familiar with the evap system on the 4th gen and not sure what to look at next.

Thanks for the reply. I did replace the fuel filter. I always hang the pump up after it stops. So I don't think i over filled it. If there is a fuel leak i can not find one. There is no leaking anywhere.
As mentioned, ICM. They get hot on the side of the Head and stop working. When you put the new one on, space it off the Head with some spacers. I put a MSD Blaster on mine when I had an LT1. Worked great.
No spark with gas going in the engine to the point the smell is probably coming out of the exhaust. Nothing EVAP related, purely no spark because bad ICM and gas going into and out of the cylinders.
