1991 Honda Accord SMELL GAS

Sounds like its dumping fuel on it-might want to check for excessive fuel pressure with a gauge, coolant temperature sensor could be stuck in the open loop mode, or the oxygen sensor is not switching to adjust fuel demand, stuck open injector/s.

You might have a leak on the injectors. When the car is cold, the smell of gas is stronger than when the engine is running (warm) Test by having somebody else turning the ignition key turn to the point you will see the engine light on the dahboard (do not crank or start the engine).
And you, as the second person with the hood open, look closely around the injectors if there is a gas leak. If there is, replace the rubber seals of all injectors. Even if there is just one leaking. Do it your self if you feel confident on doing the work or bring it to a mechanic.
Good luck.
