Something in filler tube or something making gas pump think tank is full. I had same problem someone had put paint balls in my filler neck

You best replace the filler neck so it wont leak, and operate properly. I do not think a vacuum, vapor lock has occurred.

P0171 is a lean code indicating more air than fuel being burned in the engine. P0128 is refering to the coolant temperature being below operating temperature. Usually this is caused by a defective thermostat. There are many reasons for a lean code to develop. This code may be due to the thermostat not operating correctly. Have the thermostat replaced and clear the codes to see if P0171 returns. If it does, further diagnostics will be required

thier is a 1inch round rubber connector between the plentum and the throttle body it has a big round clamp on it start the car and spray starting fluid around that rubber and i gurantee you your engine rav up that mean thier is a crack in that hose it is easy to replace cadillac are famous for that hose to crack and make your cadillac run like ****

It sounds like you may have an EGR valve sticking open. That can also cause the p0171 code, which means fuel system lean, and the p0401 which is insufficient EGR flow, kinda sounds like the valve may just be stuck open and not moving at all. replace the EGR valve.

I've had all these at the same time also. P1133 is your upstream 02 sensor, very easy, maybe 15 min to replace. p1028, is your thermostat reading a low temperature, replace this, or have someone replace it for you. P0171 is the downstream 02, difficult one to do if you're not mechanically inclined. Nothing horrible here, OK to drive, but if you want better gas milleage, get this fixed. The gas smell might be a different problem all togeher, there is a recall from a leaking gas tank.

you could put fuel into the intake, near the throttle plates, but that is not going to help. I think something got broken in your tank, Fix that and you shoudl be able to start...

Even though your O2 sensor is showing good by your scan, it could be lazy in giving readings. It has less than a 10 second window to give the reading especially if it is a heated O2 sensor. Try a Bosch unit.

Some cars have a filter in the filler neck, but I wouldn't know if yours did or not
