I have been on your forum for 3 days reading and cant seem to find an answer to my problem. So if you guys can help me GREAT!

Here it is... leading up to the problem
I recently bought my 2003 Impala to scoot around in. 1000 bucks good deal. Absolutely nothing wrong with the car. Worked great. Left the lights on while shopping so needed a boost. Car worked perfect for 1day. Then I parked the car and now it wont start. It wont turn over. Its like there is not communication between the ignition and the starter. There is no security issues. The battery is good. The starter is good. Everything in the car works. no engine light nothing. Fuses good.. I was told it might be the Neutral safety switch inside the transmission but I am not spending a grand on the car to "check" if its the issue. I ran a heavy duty wire from the starter to a push button on my dash. Starts on about a 1-2second push. I can run the car no problem, and start it with the push button but the under lying problem has baffled me and the two mechanics that looked at it. Spent about 200 on it just checking the thing out... I think I'm done and will drive as is....

but... Any suggestions or help would be appreciated. There was no indications of any problems leading up to D(ead)-day. Just parked the car like I always do then came out 5hours later and nothing.

I'm thinking short somewhere but it just doesn't make sense. Perhaps one of you gurus know the answer before I dive in and rip the freaking wiring harness out for testing... lol

 

update. After about 1 week and 25 starts with my push button I went into the store and my wife turned on the car that turned on the lights and ac and radio for about 10mins and when I came out the car was dead. So I got a boost now the passlock system is coming on every time I start the car I have to wait ten minutes. I at least know now I have a bad battery and will replace it tomarrow BUT I need to know if the passlock system in coming on every time is the car just going to go dead on me at some point. I have been reading the forums and some say yes some say no... if you have experiance with this let me know please.

thanks in advance

 

Update. Reading on another site that the car will go into security mode if you have a bad battery that has low voltage. Since it died in a matter of 10-15minutes I selected to get a new battery. 5 starts now and no lockout. So that lil problem seems to be temporarily rectified. Still using my push button I installed to start the car. Will run it for a couple months and see how it goes... if all goes well I already purchased a nice looking push button that I'll remount beside the key and leave it at that.

Wish I knew why the damn thing wont start though with the ignition... makes no sense...

again any help would be appreciated.

 

Found it. Long story short theres a green wire coming from the crank relay fuse box thats connected to a aux battery terminal right beside it. Noticed it was pinched. On closer inspection the wire was cut and so badly corroded it wasnt making a connection. Took it apart replaced it abd VOILA. 100dollars to get it checked out and make a temp fix and the fix cost me 75cents to do properly. Crazy.

 

I ran into the same issue and am looking to replace this green wire i cant figure out what gauge it is, and is there a fusible link on there as well?

Thanks hopefully this reaches you !
