Im speculating there is a fault in the system and the ecm is shutting down to avoid damage. un hooking the battery resets the ecm. youll have to start at the ignition switch and chase the issue down with a volt meter

Sounds like the ignition switch is bad, usually mounted on the steering column.

SOURCE: Replaced solenoid and battery terminals.

Sounds as if you have a bad power systems relay. On '91 and newer vehicles there is a rectangular box located on one of the fender wells that houses relays and soleniods for various vehicle component operations. Caution, this box is water tight FOR a reason.

Okay this is not so bad. First off you must check the battery. Go to harber frieght and get a cheap multimeter 5 bucks. Then put the leads on the battery terminals red on positive black on negative. What does it read. If it reads less then 12 volts your battery is shot. Now if lets say it does read 12 volts. Then the next possiblity is that there is a short or corriosion somewhere on the leads. So clean the battery terminals and connectors (bright shinny metal) And tighten everything back up. iF you get it started test the battery again this time with the car running and you should see 13, 14 volts. If not then your altenator is not putting out. Finally you must realize that somewhere the electricity is not getting to the starter. So trace the wires. All connection must be tight and corrsion free. Good luck.

I would check Cam Position Sensor as is directly related with ignition. Power loss is due to the ECU going on "limp mode" to prevent further damage.

check see if power going to ignition coil primary terminal, if not check ignition coil fuse.if power going to ignition coil primary terminal, your coils could be bad or you have ignition module fault or crankshaft position sensor and pcm fault,have vechicle code scanned many things will cause no spark conditions, make sure battery fully charged or in good shape you need good 12.6 volts from battery, for pcm and ignition to work properly.

The computer codes are 121155. What does this mean?


Code retrieval can be accessed by the ignition key or by a diagnostic readout box(DRB).To obtain the codes using the key method,set the park brake,and put the vehicle in Park/neutral.

Some 95 and later OBDII vehicles, you may be able to retrieve OBDII codes with this procedure, if equipped with digital dash:

* Turn the ignition key ON,OFF,ON,OFF,and finally ON again(ENGINE NOT RUNNING)
* The codes will start to flash on the POWER LOSS or CHECK ENGINE light.
* FLASH,pause,FLASH,FLASH=code 12

The codes showed are...


Fault Code 12
Description: Memory standby power recently lost
Power loss light: Off
Limp-in mode: None

Possible Causes:* Battery or power line recently disconnected - This code is normal if the electrical system has been worked on or the battery has recently been disconnected. It will be removed after 15 ignition switch on/off cycles.
* Low system voltage, bad battery or battery terminals - If the system recently had a power drop (due to a dead battery or bad alternator), this code will appear. If the battery terminals are bad and the engine was jumped, this code will appear.
* Bad connection or wiring - Check the wiring and connections between the battery, power module, and logic module (or SMEC). Check all fusible links and power connectors to the battery. Clean and regrease any corroded connectors with dielectric grease and repair any shorts.

Diagnostic Method
Trigger Parameters
- Logic module receives power after previously not having power


Results If Component Fails

Fault code 12 is stored. The logic module is basically telling you that it has lost power and will not remember any previously stored codes or engine sensor table data. The code will be removed after 15 ignition on/off cycles and the logic module will use default values for all look-up tables as a starting point until it "learns" the attributes of the engine.


Fault Code 11
Description: Engine not cranked since last reset or no ignition reference signal detected during cranking
Power loss light: Off
Limp-in mode: None

Possible Causes:
* Engine hasn't been cranked since last reset - Power was removed from the logic module (disconnected or dead battery, etc.) and the logic module has no memory of seeing a signal from the ignition reference sensor. Crank the engine and check for the code again. If the logic module saw a signal, the code will be cleared. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working.
* Bad connection or wiring - Check the wiring and connections between the hall effect sensor (located underneath the distributer cap) and the logic module. Check the continuity of the two 3 conductor cables coming out of the sensor--these are prone to fatiguing and breaking inside the insulation where they exit the sensor if the cables are not properly tied down. You may be able to resolder them. Clean and regrease any corroded connectors with dielectric grease and repair any shorts. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working (see above).
* Hall effect sensor failure- Check the ignition reference sensor and fuel injector sync sensor cables. They are the two, flat 3 conductor cables coming out of the sensor at the base of the distributer cap. These often fatigue where they exit from the sensor. Upon replacing the sensor, make sure the cables are clipped or tied to the distributor cap shroud (or elsewhere) so they do not swing around. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working (see above).

Diagnostic Method
Trigger Parameters
- Computer has been reset
- No signal from the ignition reference sensor has been detected

Results If Component Fails
Fault code 11 is stored and the engine will not start (even if the ignition reference sensor is working). A running engine will stall, but no code will be stored. The logic module must be reset and the engine cranked to see if the sensor is working.


Fault Code 55
Description: End of message
Power loss light: Off
Limp-in mode: None

Possible Causes:
* No further fault codes are stored. If this is the only code received, then there are no codes stored in memory. This code will always be given, even if nothing is wrong. If you do not get this code, then you may not be retreiving the codes properly, or the power loss light may be burnt out. The light should come on for 1 second when the ignition is initally turned on as a bulb test.

Diagnostic Method
Trigger Parameters
- No further codes in memory


Hope helps (remember comment and rated this)

Hi

It's highly unlikely that it would be the ignition switch, unless your losing all the power to everything.

First thing I'd check, is to make sure you don't have loose, dirty or corroded battery terminals. The number one cause for sudden power loss, especially if you go over a rough bump in the road, like rail road tracks or potholes, and your battery terminals suddenly come loose.

If the terminals are dirty, clean with a battery terminal cleaning brush available at your local parts store, and tighten.

I'd have the ignition module checked. In my expertise I'm starting to learn that bad ignition modules are a common problem in the cars with the 3.8 liter V6 engine, that are 92 or later modules in the GM line.

It cuts out when the engine reaches full operating temperature, because the capacitors inside the module, short to ground, and you can't start the car until you let it cool off, for a few minutes.

If it is determined, that the ignition switch needs replacement, I strongly suggest having a professional mechanic do the job. The the ignition switch is located on the bottom of the steering column, where the average do it yourself-er can't get to. Because your car is probably equipped with an airbag in the steering, accidental airbag deployment is not a risk you want to take.

BATTERY DIES IF NOT STARTED EVERY DAY AND POWER TO WINDOWS IS ALWAYS ON EVEN WHEN KEY IS NOT ON OR IN IGNITION


Hi and welcome to Fixya.

If you still on your origninal battery then it is well past time for a new battery. It is quite possible the battery has a dead cell and is internally discharging the battery. You can prove this by disconnecting a battery terminal over night but do the terminal disconnection immediately after the last use of the day. In the morning reconnect the terminal.... If the battery is dead you know you need a new battery. If it has a full charge in then there is a short somewhere in the chassis of the auto that will have to be located and repaired.

Based on your window power always on... it sounds like you have a bad window switch in one of the door panels or a short in one of the wires. Pull the fuse for the power windows until you are able to fix it. Window drive electric motors take a substantial amount of amperage to run or attempt to run and yes if you have either a switch problem or a window drive motor wiring problem it will drain your battery in just a few short hours. Honestly I am surprized that the fuse for the power windows has not blown. Having a switch made all the time will cause the motor and the wiring to heat up and eventually blow the fuse.
