I am stumped here. Ive tried a bunch of pin configurations and nothing seems to work.
ESP-01
When I have it wired up with the CH_PD in 3.3v then I get a constant stream of random characters. I see different pin configurations on different sites so Ive tried with gpios and rst in 3.3v and none of them in.

I have been able to flash a new firmware on it. The AT firmware with gpio 0 in ground.

I am using an ftdi232 also to communicate, set to 3.3v.

Please point me in the right direction!

Try different baud rate, try 9600 or 115200 and see if it fix your issue

Which module revision do you use?

Random stream of characters could be GPIO2 held low while booting. GPIO0 has to be HIGH (3V3 VCC via resistor) so does CH_EN (and if you want RST via resistors). GPIO2 could be either left floating (it is set to VCC while booting) or you could pull it up via a resistor.
