20 Most Recent 2007 Chevrolet Uplander Questions & Answers

If overcharging to much can damage the computer and burn up the battery, if the battery is a service free battery then it could boil the water out and if their is a spark it could cause the battery to explode. Most free maintenance batteries are not maintenance free, they can still have water added to them and need cleaning from time to time as the posts corrode up.

Sounds like it needs 're chiping to the car after the battery change

Either the battery is no good or there is a faulty connection. You must take a careful closer look at both battery cables. One of them may be damaged at either end. The wires may be corroded, frayed or loose. An eyelet may be loose or coated with corrosion and is loosing contact with the engine block, battery terminal or fender. Please check your repairs carefully and let me know if there is anything else. Good Luck.

underneath the starter.left of the engine

Look way up under the dash, near the end of the carpet. What you are looking for is (usually) a black hose, thicker than a vacuum line, but less than a heater hose, for example.
What happens is a passenger unknowingly kicks the hose off the heater/AC box, then it leaks out. The hose is a hand press fit.
Rarely have I found the hose plugged. If that happened, you would likely have a complaint of fluid being blown out the a/c vents.

This is not that clean cut, ECM failure is not that common. The battery died and that caused the no start. This could also account for the setting of that code because of loss of field charge in the alternator. A dealership can write off parts that are not bad, if they did not do the work, you are stuck with the parts. ECM is not cheap. I would check the CPS first.

Without testing we'd only be guessing ! You have no idea of the complexity of the electronics on your vehicle . Replacing the ECM would mean a trip back to the dealer to have it programmed . Without programming your vehicle will never start . You had new battery an alternator installed , did it start an run when you picked it up. The charging system on your vehicle is computer controlled . DTC P0621
DTC P0621 : Generator L-Terminal Circuit
The engine control module (ECM) uses the generator turn ON signal circuit to control the load of the generator on the engine. A high side driver in the ECM applies a voltage to the voltage regulator. This signals the voltage regulator to turn the field circuit ON and OFF. The ECM monitors the state of the generator turn ON signal circuit. The ECM should detect low voltage on generator turn on signal circuit when the ignition is ON and the engine is OFF, or when the charging system malfunctions. With the engine running, the ECM should detect high voltage on the generator turn on signal circuit. The ECM performs key ON and RUN tests to determine the status of the generator turn on signal circuit.

Your best bet take it back to the dealer .

Are You sure.?. Most fuel pumps will give a warning before it quits on you. Check your relays and fuses under the hood. You may also have a bad shut-off switch the shuts the pump down in the event of an accident.. Check them all. Removing a fuel pump is very expensive , as it is located inside the gas tank.
