Question about 1996 Chevrolet Cavalier

1 Answer

I have a 96 Cavalier LS 2.4L, it died on the road while my wife was driving. Some numbnut tried to jumpstart it and hook up the cables wrong... So far I have replaced the bettery, starter, ignition switch, and engine computer. The car starts and imediately shuts off with a blinking theft system light on. The theft system is on steady unless I try to start the car. I sent the engine computer back to recheck the program and pick it up today. Is there anything else I should check before I hook up the new computer?

After you put in the ecu, do the crank relearn, everyone knows how to do that since its common knowledge, and you're good to go.
Here is how it's done: Ensure that your battery is fully charged before attempting the relearn procedure. Do not leave any battery charger or jumper cables attached to the battery. Close the hood completely. Some applications require that the doors remain closed during the procedure.

1. Rotate the key to the start position to attempt to start the vehicle (the vehicle will not start).
Allow the key to return to the all position (same as if the vehicle would have started). The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
2. When the theft system telltale stops flashing (or turns oft) turn the key to the off position for 5 seconds and then attempt to start the vehicle. The vehicle should start on this cycle.
3. Once the vehicle is running, the password relearn is complete.

3. When the theft system telltale stops flashing (or turns off) turn the key to the off position for 5 seconds and then attempt to start the vehicle.
4. Repeat steps 1 through 3 two more times for a total of 3 cycles/30 minutes.
5. On the next cycle of turning the ignition key from off to crank the vehicle should start
6. Once the vehicle is running, the password is learned and this completes the cycle.
7. Clear any DTC's with a scan tool if necessary. DTC history will be cleared after 100 ignition cycles.

    This didn't work. The light never goes out. I sat there for over 20 minutes, and no change. I bought a diognostic tool to hook up to the OBDII interface. It says its not receiving a list of sensor signals: C/EV/O/OH/E...but no stored faults. Could the missing signals be because the car is not running?

    Check all your fuses, your ECM is not getting any power to it or one of the sensor's are not sending a signal which is causing your ecm to shut the engine down. Keep me posted, be glad to help you get your car running again soon.

My 2009 hhr won't start. The first time the dealer said there was a wire that was loose wire to the fuse box, fixed wire. The second time the dealer said the battery was bad, replaced battery. The third...

sounds like a bad ground somewhere. that can burn out power wires due to a high amp draw and cause the battery not to charge. try hooking up the negitive cable directly to the engine to jumpstart it. if that works and the car dies as soon as you disconnect the cables a bad ground is very likely. and I have noticed the new gms are very weak in the charging/battery department. They are using very cheep batterys ,die very easy. also check fuses.

My 96 nissan quest died while driving

Check your battery with a good volt meter , you should have on average 13.2 volts when fully charged . If not check to be sure your belt tension is correct and it’s not slipping. If the belt isn’t slipping take your alternator to your local parts place and have it checked out . If you have good charge in the battery check to see if your engine has a distributor or if it’s a coil pack system . If it is distributor check the pick up coil . If it’s has gone bad you will get no spark to your plugs .

99 cavalier engine

I just changed a 2.4 in my 96. I pulled the whole thing because I coudn't get at the converter to flywheel bolts. After reading further, I saw information to pull the trans out through the drivers wheel well without the engine. They removed the starter to access the flywheel bolts to the converter.
I haven't tried it but it would make sense and it does make it a lot easier. Without the trans attached, you wouldn't need to remove the master cylinder or beat the sh-t out of the battery tray to get the think out.
