Hi everyone new member here to the forum. I've got a 2001 monte carlo with a l67 swap that won't start after sitting for a while. I've been trying to figure out what's wrong with the car for a couple days now and I've narrowed it down to a fueling problem. Fuel pump primes, and I'm getting pressure at the rail. The injectors aren't firing though. The car tried starting with some starting fluid so I pulled the rail and injectors and can't see anything wrong with them. Anybody have an idea what else could cause the injectors to not fire. I've checked and double checked the fuses, and tried unplugging the maf. I also checked for a code but it's not showing anything. Any and all help would be greatly appreciated.
Thanks
