You need to check fuel filter and fuel pressure. A fuel pressure gauge is about a $50 item. You can listen for the fuel pump by just turning the key to the Run position w/o starting. It's in the tank and you should be able to hear it run for a short period of time as it builds up pressure to about 50-60 psi. It should hold that pressure for a period of time after you turn the key off.
The TPMS light (Tire Pressure Monitoring System) for that vehicle should function as follows.
If the light is on and steady, it means that the pressure in one or more of the tires is too low, and if the light is flashing, then it indicates that one or more of the tires are over-inflated.
1. Turn the ignition key to the "On" or "Run" position but do not start the vehicle. (If the vehicle has an electronic keyless ignition then place the ignition switch in the "ACCY" position)
2. Press the "Lock" and "Unlock" buttons at the same time on the vehicles remote key fob, and keep holding the two buttons down until you hear the horn beep, and usually this takes around five seconds. The horn beep will indicate that the learn cycle has begun.
3. Re-learn the TPMS system. Deflate or inflate air into the driver-side front tire for approximately 8 to 10 seconds and then listen for the horn to beep one time. (the horn might beep before the 8 to 10 second re-learn, or it could even take as long as 30 seconds after)
4. Repeat steps 2 and 3 for the remaining three tires. Also, the remaining three tires must be checked in the exact following order, the passenger-side front tire, the passenger-side rear tire and finally the driver-side rear tire. After the final TPMS sensor has re-learned then the horn will beep twice.
5. Listen for the horn to beep twice. When the horn does beep twice, it wikll be the indicator that the TPMSsystem has re-learned and reset.
6. Turn the ignition switch to the "Off" position, and then be certain that all four tires have the correct tire pressure as recommended on the drivers door, and the next time that the ignition is turned on, the tire pressure light should be reset.

Good Evening. Your antilock brake system when it has an error or problem will give an error code to the ABS computer, and will also turn on your traction off and brake light. The easiest way to diagnose the problem is contact a local repair garage and see if you can have them scan and read the codes, in most cases it ends up being a hub assembly or low brake fluid (which is something i would check first). However it could be more than that and it is more cost effective to know what is wrong from the code stored in the system. As far as your low tire pressure light that can be reset on your dash by pushing gauge/info until tire pressure comes up and then holding reset until it says reset. There are sensors in your wheels and sometimes fail. Be sure that your tires are all 32-35psi your tires will say on the side as far as recommended psi and if the problem continues your local tire dealer/installers have equipment to check and diagnose these sensors. I hope this helps and you have a good evening.
1. check and make sure that your tires are inflated to the correct pressure
2. turn the ignition switch to the ON position. If the low tire
pressure warning light comes on, push and hold the tire pressure
warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns
off and then release the switch.
3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.
Tire pressure always changes... when you drive your vehicle for a long period of time the tires' temperature goes up along with the pressure in your tires, the molecules in the air inside your tires get excited (hot) when your vehicle is immobile for a while your tires' temperature goes down along with the pressure in your tires, the molecules in the air inside your tires get compacted (cold) This is the best time to get a true PSI reading from your tires.... the recommended tire pressure on most tires should be set at 35PSI But there might be a problem with your sensors, I work with TOYOTA their sensors are set up to where when the PSI on your tires drops below the 35PSI, the tire pressure light would then come on. You should also check if your spare tire comes equipped with pressure sensors, which in most cases they do, depending on the type of tire the PSI on spare tires will usually range from 35PSI- 80PSI you can check your owners manual for this, or simply read the recommended PSI written on the tire.
Look for a sticker on the drivers door panel. It will tell you what pressure to set for the tires. The owners manual may also contain this information. It is normal for a radial tire to look a little flat.
