Take it an have it diagnosed rather then looking for a magical fix on here ! Without testing , viewing scan data ,we would only be gussing . We could suggest a number of thing's that could cause this . Are you willing to replace parts that may not fix the problem. (waste of money ) !

contacting the customer service department of the manufacturer of the car with that vin number will reveal what engine was used , in fact if you ask for the BOM ( bill of material) that list will show exactly what parts were used in the manufacture of the car

The problem is probably the blower motor resistor. I'm not sure where yours is located exactly. They can be on the firewall under the hood or some are near the blower motor under the dash.

DTC P0449 Evaporative Emission (EVAP) vent Solenoid Control Circuit
The vent solenoid is not working properly. The ecm driver could be defective, the wiring could be broken, or the vent solenoid just isn't working.

If fuel is coming out exhaust - Do not try and crank as it could catch fire. a computer sensor or fuel injector is pumping so much fuel the engine can not burn it all. There very likely is fuel in the oilas well. This is a serious problem and needs to be towed to a knowledgeable mechanic

What does your OBDII tell you? If you don't have one for <$10.00 you can get a bluetooth, and link your smart phone to read the codes. Cars have codes which are specific, however if you don't have a shop manual I'm sure if you google OBDII codes for your vehicle expect about 1,200,000 hits,LOL If you have a good spark, the other thing an engine needs to run is fuel, so look at the fuses, and check the relay(i.e. energize the relay and see if it closes. Also see what the resistance is. contacts could be burned and no longer make good contact. When was the last time you changed the filter? Cheap and usually not a major project. If you want take a glass jar, drill a hole in the lid, insert a tube from the furthest end of the fuel line available. BTW point with the jar and a hole which is a little tight is you will have no leakage or overflow. You can return it to the tank if you like, or just throw it on the driveway and let it evaporate,lol.

Probably no oil pressure.. The light does not tell you if you have oil.. but if you have oil pressure

First, with the door almost tight; spray the inside area with wd40 to coat the painted area then, use a test spray paint color to see if the paint will stick to the wd40 and the wipe off, if it does you will be able to close the door and open the front door with the rear door closed and spray the hinge area with a paint to make your marker then use a jack with cloth at the bottom to protect the new door to aid in tightening and realingning

Back doors dont unlock with remote? Clean the electrical contacts in the door jam

If you are using the gauge that came with the vehicle it's accuracy is not great. These gauges were designed so that at a glance you can see the needle is pointing basically to the middle of the dial. As long as the needle is more od less there, you're okay but the numbers mean nothing due to the gauges in accuracy. If you really want to check the oil pressure, the procedure is pretty easy but requires decent equipment as well as the knowledge of where to tap into the pressurized oil system.

you have to remove the fuel tank to get access to fuel pump and sending unit hope it helps

cooling fan is activate for many reasons like engine hot, A/C high pressure, if there engine code and so on does check engine light is on????? hope it helps

Why the vent valve solenoid control circuit shows constant volts on both wires when connected?

There is a solenoid that open and closes with 12 volts, usually located close to the fuel filler tube area. This open to allow you to fill your tank, then closes after some inputs for the computer are satisfied, and then a pressure sensor verifies the system is working. First, make sure the cgas cap is tight, and if the light doesn't go away in a couple days of normal driving, get the solenoid checked.
