Hello .
I have changed my O2 sensor and I have the same problem when I start my truck the engine start and stop immediately then I restart he run but don't keep idle ( He smell gasoline ).
I think maybe it is the T P sensor faille but I'm not sure and I have problem to test parts because I live in FRANCE and there isn't a lot of FORD F150 XLT 1990 5 L.
Thank for help.

You didn't specifically ask what those other codes were for but # 63 is Throttle Position sensor below minimum (possible short) and # 95 is Fuel Pump circuit failure -PCM to GRD. This is according to my Haynes manual. I'm not sure if one problem could cause one or both of the other codes or not.
With the gas smell so strong, you might want to take the vacuum line off the fuel pressure regulator and make sure there is no gas in it indicating a failed diaphragm.
