I just bought a 2003 Suzuki Aerio do you know where I can get an owners manual? preferably free

First of all, if the engine turns over, you DON'T need a starter or an ignition switch. Don't fall into the 'let's try replacing this' method of car repair! It is costly and never works.

First replace the cap cap, it is part of the pressurized fuel system and may be the answer to all the issues. $20 from Walmart, or $15 from Napa Auto Parts.

Then connect a code reader and find why that Engine Light comes on. Your vehicle has a computer that records everything that is wrong with it. A cheap code reader gives you the basics, a $5,000 scan tool computer tells you everything, historically and in real time as the vehicle is starting of being driven.

The other thing to check is that the battery is good. Interstate will test for you for free in the parking lot and only takes 2 minutes including the printout. I think AutoZone and Napa also does it.

You may just need a oil change, check the owners manual. Or take it too a Autozone or O'reilly auto parts or a major auto parts chain. they will hook up a hand held analyzer to your car's ecm and read the code for free. They will let you know what that code means and go from there.

PARKING BRAKE HAS TO ADJUSTED IF OUT OF ADJUSTMENT.

Check the eBay website. They usually have a lot of various owner manuals for sale on the site. I hope this helps!
