#800 of 1226 2003 pontiac grand am by monet1

After reading all the other postings, i am having similar problems I purchased a used 2003 pontiac grand am which up until 3 months ago have not given me any problems. One day it didn't start until after 2 to 3 tries, when that started I took it back to precision tune for coil change and make sure it wasn't time for a tune up. At that time I got a Diagnostic completed and no codes showed up. Once I was trying to leave it wouldnt crank. so they ran another test nd then codes showed up. which were park lamp control circuit malfunction, horn relay coil circuit low, security system sensor data circuit high, loss of serial comm for class 2 and loss comm/w restraints control and they suspected Ignition switch. and also showed evidence of needing a fuel filter. and they recommended a dealer to complete everything. Well took it to the dealer and once again completed another diagnostic and they found completely different codes. It states that BCM has theft codes stored,needs pass lock sensor. there price was to high and they recommended local auto electrician. and I must say he is unbelievable with his work but after trying to fix everything including crank shaft was replace, wouldnt start after 2 days. ignition switch replace still would start, come kind of coil replace still wouldnt start now he has given up and still having the same problems what can I do. I also replace fuel filter, coil on boot autlt

here's my latest. the problem is the car is stalling out while running. the last time the car stalled i knew about the passlock feature from here and i checked some things. first, car would crank but not start. when the car wouldnt start, the oil light, security light and battery light stayed on. tried waiting the 10 minutes to rest the passlock, but no difference. 4 hours later went back to the car and it started and we dropped it at the mechanic. second, dealership confirmed passlock will never cut the power if it fails during running because it's too dangerous to lose power steering and power brakes, etc if the engine were to shut off while driving
So, after it sat thru the weekend, mechanic couldn't get the car to fail to start for couple of days. finally one day it wouldn't start and he found there was no spark. he found out the ignition fuse under the hood was good but it wasn't getting any juice at the time, when before it had juice when the car started no problem. he thinks there must be a problem somewhere along the path so he jumped it with a temporary wire. he's got a wire going from the blower fuse to the ignition pack somewhere. he picked the blower since it's only got juice when the key is in the on position. he did that last thursday and since then the car has started on the 1st time everytime. ill start taking it on longer and longer trips until we're confident that solved the problem, then he'll make a nicer wire job and we'll just keep it that way. we're going to trade the car in towards something better in the next few months and the dealer can clean it up.
My mechanic also found some highlighted lines in the fuse panel map under the hood so looks like the car has had electrical work in the past. He has a theory that perhaps somewhere in the wiring or harness the ignition line is frayed or corroded and perhaps when the wire heats up it can't carry the juice necessary to keep ignition going. then the car stops, won't restart, until the wire cools down and can carry current again. just a theory.
if you like i can post a pic of the temporary wire he's got, not sure where he spliced into the ignition by the coilpacks. but ask your mechanic to check the ignition fuse juice both when the car starts and not.
hope this helps, much luck with your problem, hopefully this holds on our car.

#802 of 1226 2001 Grand Am SE Passlock Issue by pontiacowner

passlock problems go to start the car and it wont start the have to turn to on and wait 10-15mins or more till security light goes out to start the car. I have already had to tow it once because of this problem and now its back in the shop again for the same problem it is a 2001 grand am. Research this online and find that there are alot of others out there with the same problem. We should get together and file a lawsuit. since GM/Pontiac is aware of this and has not taken the steps to correct the problem is definitely not a maintenance issues it clear that this is a manufacturing issue.

Post #21 in this forum has the solution to the passlock system. I installed the toggle switch and have not had a problem since.

I guess it is time to repeat my simple solution to the Alero or Grand Am owners' passlok problem as described in my post # 695 dated Oct 13, 2009. And now after 16 months I have not had a single starting problem. Those owners, who admitted having tried it, were successful. Other experienced Grand AM owners tried to explain it. Believe me, this solution is not rocket science, OR maybe I'm just lucky. And I QUOTE .............
 At 36,000 miles my 2001 Olds Alero started having passlock starting problems. At first it was every other month and then after 2 years it happened with every other turn of the key. Since I am not the least bit mechanically inclined, I tried any and all procedures suggested on the internet except cutting wires, or installing a new switch. Eight months ago I decided to clean the grooves on my ignition key with a squirt of 3 in 1 oil. THE CAR STARTED RIGHT UP. I did it again for the next 3 days to gain little confidence in the procedure. THE ALERO CONTINUES TO START EVERY TIME
  Now once a month I oil the key, push it in and out of the switch slowly a couple times. When starting the car, do not jam the key in quickly and turn. Take your time. It seems to be a very sensitive switch, and needs a little TLC to prevent dirt build up. Try it. A little 3 in 1 oil squirt might save you a $500 repair bill. I told my GM dealer mechanic about this solution. He said "Yeah, it might work"
 UNQUOTE
  
 If this procedure works for you, or any other Grand Am owner I would appreciate hearing your results-good or bad. Don't use any fancy ignition key lubrication from an auto parts store. Just a little dab of plain, old 3 in 1 oil ...........Ja

The yellow wire has nothing to do with stalling .
This doesn't sound like a passlock issue at all .
