How to fix a timing chain for a 2004 chevy malibu

There is no adjustment. If it's loose then it has stretched too far and needs replaced. It's best to replace the cam and crankshaft gears at the same time .

they might have left wires loose on the cam or crank sensor

autozone library has a good diagram

take it in to a mechanic because if you get the timing wrong you'll mess up the engine

No.

you can easily bypass the security system entirely. There is a great write-up here http://newrockies.ca . That was the only solution that saved my Park Avenue.

I had the same issue on my 2005 Malibu. They unlocked over and over, 5-10 times at a time, then would stop for a bit, then would do it again. I had to replace the remote to fix.

That engine does not have a timing belt, it has a timing chain and therefore much easier to work with as it can only go on a certain way, the primary focus being getting the dots on the timing chain sprockets lined up properly.

I believe, with the engine at Top Dead Center on cylinder #1, the dots will be facing each other. That is to say, the do on the cam sprocket will be facing the dot on the crank sprocket.
