91 camry fuse problem?. it's in great running condition.

have vehicle scanned --abs -brake -can be a hub failure -bcm problem - or just fuses blown --but before just changing out more unnecessary parts have vehicle for the trouble code[s]

As with any no start condition, you will need to figure out if you are dealing with a fuel problem or spark problem. If the engine is cranking normally we will assume the timing belt is ok.
You can check for spark at the plugs, and try spraying carb cleaner into the intake hose.
Also check the computer for trouble codes and the fuel pressure at the injectors.

[Information] For a 2002 Toyota Camry, the Daytime Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to the center of the vehicle front) at a reduced power.

[The troubleshooting process:] Review the Owner's Manual and ensure the test configuration matches the following criteria:
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."

2. Set the Test Conditions according to Step 1 above.

3. Check the headlight bulbs to ensure they are not burned out. If one burns out, there is a fair chance that the other would have burned out at the same time. Replace as necessary. In this case, if the high beams operate, the DRLs should also operate.
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function Switch on Turn Signals in "DRL" position, headlight switch off (repeating what the manual says -- it should be obvious that in the "DRL" position, the headlight switch should be off / do not have the switch positioned to "High Beam"), and the Parking Brake "off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box. there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3). Any one of them could be bad (stuck or burned out). Test (step 4).
7. Other less likely possible issues could be that the Multi-function Switch is broken or a connection / wire is broken. [Beyond the scope of this process.]

My problem was that the test configuration did not have the engine running and parking brake off - Step 1. Problem solved with much thought, repetitive tests on the vehicle and going back to the basics -- what does the Owner's Manual say and where are the applicable fuses and relays located?

The cause is most probably a current drain on the battery when the vehicle is switched off.

Check for a drain current from the battery while the vehicle is standing with engine and all electrical system turned OFF -
[ while in this condition, if you don't have a current meter, temporarily connect a small bulb (6-12W) in series with the main battery ground cable - lamp glow indicates current drain - remove fuses, disconnect items to identify cause of current drain],

Also check alterator output voltage (measured across the battery terminals) is approx 14.5V when engine is running and electric system is loaded with headlights or blower fan on.

check the fuse under the fuse box in the engine compartment. it's the main fuse for all components on the care. should be able to locate it under that fuse box.

Probably the battery. The battery may have enough voltage for the lights to work; however, this may not be enough voltage to start the car.

Find someone with cables to give you a jump start. Then take the car by an auto parts place and have them load test your battery. Most stores do this at no charge.

Glad to hear that you are up and running! Please feel free to call upon me at anytime. The graciousness of a FixYa rating for my assistance would be greatly appreciated.

If there is anything, that is in any way "burnt", it needs to be replaced.
I would try a local auto recycler before I ordered a new light failure sensor.

try a higher amp fuse

I came across a couple of toyota service bulletins addressing these issues (as I am also suffering from rough idling and persistent check engine light(that sometimes blinks)):

Should a M.I.L. “ON” condition with DTC P1133 be encountered, perform diagnostic
procedures as described in the Repair Manual.
If the problem source cannot be identified after checking all affected areas according
to the Repair Manual, the cause may be an Air/Fuel Ratio Sensor malfunction. In this
case, replace the Air/Fuel Ratio Sensor with the current part number listed above.
If the Exhaust Manifold threads are damaged by removal of the sensor, they can be
repaired by the proper use of a M18 x 1.5 tap.

1. Remove all six fuel injectors for
verification of production information.
Affected injectors will be labeled with
a vendor part number of
“23250–0A010“ and have a
production date code number of “828“
or lower (see illustration for number
locations).
2. After determining that one or more of
the injectors are affected, replace all
six injectors with the above applicable
part number.
3. Clear the DTC, if present, and verify
that the vehicle now operates as
designed.
