Hard to start, smell gas, and it seems to flood when its cold.
When it is cold, sometimes i can not get the jeep to start. i get a smell of gas when i do try to start it. the fuel pump was replaced 6 months ago. i have to hold the gas down when this happens as i try to turn the ignition and have to keep the key turned on until the engine catches.

You have a bad fule pressure regulator to check to see if this is the problem look on your fule rail and you will see a round piece that has a vaccume line on it start car and un plug the line if gas is comming out of the regulator its bad. it floods the motor with gas it drives ok because you are hitting the gas and it allows more air in to compensate for the xtra fule, but once you let off gas its flooding out. Thats why you smell it and all the black smoke. hope this helps.
You may smell the fumes as the motor may be getting flooded, I know most people think this can't happen with fuel injection, but if there's a igntion problem, yes it can. [ you may want to do a tune-up = plugs wires etc.] . If you have a hard start, hold the gas pedal to the floor and crank the engine. The computer will go into a CLEAR FLOOD mode reducing the amount of fuel from the injectors to help it start. You may also have the coolant tempature sensor checked, as this will sometimes cause a starting problem.
The first thing I would do since you think it was flooded is to replace the sparkplugs, sometimes if a spark plug has been washed out with gas you cannot get it completely dried out. After you replace sparkplugs try to start the engine. If the engine starts I would still recommend that you change your oil because of fuel saturation. If your engine fails to start I would suspect that you have a bad crankshaft position sensor as it is known to give problems. The crankshaft position sensor is located on the top of the transmission bell housing on the drivers side.
