OK, Van was running fine wife and kids in it all day driving around town. Came home sat for about 2 hours and went to leave and click click like the battery was dead. Put a charger on it, and tried to start is and it s chugging, couching and weezing. Won't stay running to save its life. Whiel it is trying to run, the tach ans speedo are dead. The relays are clicking like crazy. We changed out the battery and the results were the same. Tried to check the codes through the "CEL", I think it is giving me an 11, 12, 21 and maybe 23. But when I put my AutoTapon it nothing is coming up. When I say nothing I mean the AutoTap is not seeing the system. It says detecting vehicle and PCM, but when the displays should come up there is nothing. I checked my Chevy Truck and a friends car and the AutoTap works fine.
Any ideas on a better to try and read codes. We have disconnected that battery and cycled the key to bring up the codes, but the sequencing does not seem to be right. Could the PCM have taken a dump ?
Anyone with any ideas on this. I hate to take it to a stealership.
Thanks in advance,
JMD

I'm not sure, but bad gas can probably cause this also. Maybe using Leaded Fuel or even water in the tank, not 100% sure though.
I really think it's a bad PCM.
MIL Code 11:
Intermittent Loss of CMP or CKP
Name of Code:
Intermittent Loss of CMP (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/56562517) or CKP (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857164)
When Monitored:
Engine running over 7 seconds.
Set Condition:
When the expected cam signal level disagrees with the actual cam signal level.
Theory of Operation:
After the engine has been started, the powertrain control module (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/101367125) maintains an expected camshaft port level value. At every 69 degree crank edge this value is toggled to reflect the expected change in the cam level. At every crank tailing edge this value is compared to the true camshaft port level. If there is a disagreement between the two values, then the trouble code is matured and set
At this time, the powertrain control module (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/101367125) is forced back into a Spark Start mode and it attempts to synchronize the cam and crank signals.
Possible INTERMITTENT Causes:
Open or shorted 8-volt Supply circuit
Open sensor ground
Open or shorted signal circuit
Excessive crankshaft sensor clearance
Excessive camshaft sensor clearance
Damaged camshaft sensor rotating component
Damaged crankshaft sensor rotating component
Failed sensor
Failed PCM

The PCM supplies 8-volts and a sensor ground to the CKP sensor. The crankshaft position sensor (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857164) signal circuit has 5-volt pull-up voltage from the PCM. The sensor signal is created by the slots cut in the flywheel passing under the sensor. When a slot is under the sensor, the signal is high (5.0V). When the metal between the slots is under the sensor, the signal is low (0.3V).
Possible Causes:
Open or shorted 8-volt supply circuit
Open sensor ground
Open or shorted signal circuit
Excessive clearance between the sensor and flywheel
Damaged flywheel
Failed sensor
Failed PCM
Mis-Fire Adaptive Numerator At Limit
CKP sensor target windows have too much variation.

When Monitored:
With the engine running for more than 3 minutes, engine temperature greater than 90°F, after reaching a vehicle speed of 10 mph for 30 seconds, at idle with the transmission in drive (auto) or in neutral (manual).
Set Condition:
The upstream oxygen sensor (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857572) signal voltage is switching from below 0.39 volt to above 0.6 volt and back fewer times than required.
Theory of Operation:
Effective control of exhaust emissions is achieved by an oxygen feedback system, of which the most important element is the upstream oxygen sensor (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857572) (O2S (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857572)), which is located in the exhaust path. Once the sensor reaches its normal operating temperature of 300°-350°C (572°-662°F), it generates a voltage inversely proportional to the amount of oxygen in the exhaust. This voltage is used to calculate the fuel injector (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34858641/34859103) pulse width, which maintains the optimum 14.7 to 1 air/fuel (A/F) ratio that is required for the catalytic converter (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857699/34856671) to best control exhaust emissions. Response rate is the time required for the sensor to detect changes in the exhaust gas oxygen content, it switches from lean to rich if it is exposed to a richer than optimum A/F mixture, or vice versa. The O2S output voltage ranges from 0 to 1 volt. A good sensor easily generates an output voltage in this range as it is exposed to different oxygen concentrations. To detect a shift in the A/F mixture (lean or rich), the Output voltage has to change beyond a threshold value. A malfunctioning sensor could have difficulty changing beyond the thresholds.

The PCM receives exhaust gas information from this O2 sensor (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857572). The sensor detects exhaust gas content by a galvanic reaction within the sensor that produces a voltage after measuring the amount of oxygen in the exhaust gases, the downstream oxygen sensor tells the PCM how well the catalytic converter (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857699/34856671) is oxidizing HO and CO components and reducing NOx components in the engine exhaust gas. Variations in the signals from this O2 sensor serve as an indicator of oxygen content. The catalytic converter absorbs the oxygen in the exhaust gas when the fuel/air mixture is lean. The downstream O2 sensor indicates a deficiency of oxygen when the upstream O2 sensor detects an abundance of oxygen and vice versa.

When Monitored:
With the vehicle engine running for more than two minutes, engine temperature greater than 170°F, in closed loop.
Set Condition:
If oxygen sensor (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857572) voltage stays between 0.29 volts and 0.72 volts for 30 seconds, the PCM pulls the sensor voltage to 5.0 volts for 60 seconds and monitors the sensor voltage. If the voltage stays at 5.0 volts, this trouble code will set, indicating no activities.
Theory of Operation:
Effective control of exhaust emissions is achieved by an oxygen feedback system. The downstream oxygen sensor (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857572) (O2S (http://www.alldatadiy.com/alldata/AFI~V6609151~C30621~R0~OD~N/0/41746574/56417202/56417205/56419253/34853741/34857029/34857030/34857572)), located in the exhaust path, monitors the exhaust emissions. Once the sensor reaches its normal operating temperature of 300°-350°C (572°-662°F), it generates a voltage inversely proportional to the amount of oxygen in the exhaust. This voltage is used to calculate the efficiency of the catalytic converter. The downstream oxygen sensor is monitored for proper response to assure a correct catalytic converter efficiency calculation. A good sensor will indicate a rich condition when at WOT (due to the enriched F/A ratio), and a lean condition when in decel fuel shut-off (due to the lean F/A ratio).

Sounds like the pcm suffered a voltage spike, also check battery cables and connectors for corrosion. If you have access to another pcm try it...
