03 grand am 3.4l no crank at all. All the light on dash work good fuel pressure starter spins and engine starts and then stalls when jumping the starter directly installed new pass lock switch and...


If the Passlock switch has been replaced, the computer has to "learn" the new Passlock code. You will need to hook up a battery charger to perform the learning process. (It takes about 30 minutes with the key in the "ON" position and it will run the battery down.)

Step 1:

Turn the key to the "START" position and release to the "RUN" position. The "SECURITY" light will be flashing. After about 10 minutes, the light will stop flashing.
.
Step 2:

Turn the key "OFF" then back to the "RUN" position. (Do NOT try to crank it yet) The light will start flashing again. Wait about 10 minutes for it to stop flashing.
.
Step 3:
.
Turn the key "OFF" and back to "RUN" one last time. The light will be flashing again. This time, when it stops flashing, do not turn the ignition off. Instead, turn the key from the "RUN" position to "START". The engine should start and run. The computer has now learned the new Passlock code.

Car wont start, changed ecm, plugs, started but died, what should i do


After you put in the ecu, do the crank relearn, and you're good to go.
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 tostart the vehicle. The vehicle should start on this cycle.
3. Once the vehicle is running, the password relearn is complete.

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.

Hi. I have a 99 Pontiac Grand Am. I've had that problem before. All I did was...whenever the security light would flash...and the car wouldn't start...I would take the key out...and just sit there and wait for about 10 to 15 minutes. Then the red light would stop flashing....and the car would start. That would happen about 2 times a year. Now I'm having trouble getting it to start. It's trying to...but won't turn over. My mechanic put a new computer....but now he doesn't know what is wrong. Please help. Thanks.

No keys


If you want to initiate a new master key.... 1. Insert new key into ignition cylinder and turn it to the ON (RUN) position. The security light on the dash will flash for fifteen minutes.
2. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder OFF and then back to the ON (RUN) position. The security light on the dash will flash for fifteen more minutes.
3. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder to OFF and then back ON (RUN) position. The dash will flash for fifteen more minutes.
4. After the security light stops flashing the third time, the new key has been programmed into the vehicles computer and will operate the car. It has replaced ALL the previous electronic key codes and is the ONLY key programmed into the vehicles computer.

The dealership should be able to do this for you without a current key, of course this means towing the vehicle to them. See if they will sell you a key and you program it yourself.

hope this helps. I found the above info at FordF150.net

Key Does Not Work


It could be that chip inside key just went bad. Do u have a 3rd key? That works? If so take the 2 good keys and turn the igntion to run postion for 3 secs each then do the same for the 3rd key and this will reprogram it if the chip is ok. If you do not have 2 good keys then u will have to have a scan tool that will link up with PATS system and perform security access to reprogram it.

Lights flashing, then not working at all


From what you are describing it sounds as if the headlight switch has gone bad.  That switch controls not only the headlights but the tail lights and all dash lights.  Everything that IS working is connected to other switches not related to the headlight switch.  You can either buy a new one or get a used one from a junk yard or ebay.  Pay particular attention when getting a replacement as there are 3 different models which vary depending on options such as Auto mode and Foglights.   Replacement is easy.  Using a flat screwdriver carefully pry off the trim cover around the switch. The switch is held in with some screws.  Be careful disconnecting the wires so as not to break the locking tabs. The trim just pushes firmly back into place.
