Hi Jenelle, The problem could be related to the anti theft unit or a defective crankshaft or camshaft pick up sensor. There are other reasons why the vehicle refuses to start and the best way to discover what the actual problem is, is to have a diagnostic scan carried out. Most good workshops have them and many are of the portable type. If you cannot get the vehicle to the technician, they can come to you. Regards John

SOURCE: Jeep needs to crank twice to start + rich gas smells once started

That code PO455 is indicating that you have a fuel vapor leak somewhere in the system. I'd check from purge canister back taking a close look at all the vapor hose to the tank. If all that check out, purge solenoid & canister would be my next area to check. That's probably what your smelling , so it might be easier than you think to sniff out the source.

SOURCE: jeep grand cherokee stalls after warming up

You need to check components again when the engine is hot and in no-start condition, otherwise, you will get bad info...obviously whichever part is doing this works fine cold. ones that react most to heat are crank pickup, ignition coil and the fuel pump.(bad ones get hot and bind up)
