Thanks for all the suggestions, I just got some more information that may be helpfull. when the timing chain came off, the exhaust cam shaft was off mark, tried to realign by turning it one complete rotation clock wise until it was back up to mark. when it was turned it sounded like a spring was unwinding in the motor. was it suppose to sound like that? when the cam was turned it would only go one way, was this correct? could this have off set things? if so how should we go about correcting it?

Re: 2001 alero new timing chain and coils
You will have to aligne the crankshaft at TDC =top dead center i.e the piston on # 1 should be on top and the # 4 too i.e.if its a 4 cylinder engine.
If the camshaft doesnt fully turn ...i.e. rotating 360 degrees.. then its the pistons which is obstructing the rotation.....so rotate the crankshat and keep the pistons say half way thn bring the camshaft to its mark ..once done thn you can set the crankshaft to TDC.
you should be ok here !! GOOD-LUCK

Need to Know what SIZE Engine to give this Internal Technical Info to you. Externaly The Crank Sensor picks it up from Harmonic Ballancer and so there are NO EXTERNAL Marks Nor Does the Manufacturer Provide this Info
There is a 2.4L DOHC Engine and there is a PROCEDURE Rather than MARKS on the 2.4L and Requires you to Fallow EACH STEP EXACTLY and in a Very Long Texting . But On the> 3.4L Engine and INTERNALY on the 3.4L the Marks Alighn With #1 @ TDC CAM Mark is STRAIGHT DOWN and the CRANK MARK is SRTAIGHT UP < This is Internal marks on the 3.4L Engine

$1000 is appropriate at a chain garage or dealership as long as it carrys a warrenty. with the economy the way it is if you want to save money you can hire a mechanic to do it as sidework but you are taking your chances on how quick he will do it and you have to make sure he knows what he is doing. if you need the car done quickly and are not a good judge of character shell out the $1000. If you can spot someone bull"s"ing and have a little more time offer a mechanic $500. Sometimes you can drive up to a shop and bypass the office and ask the mechanic directly if he does sidework. Most will love the oppertunity because they are paid nowhere near what you pay for the service.
Are you getting fuel? When you turn the ignition switch to on , does the pump energize? If not make sure the relay is ok. If you have fuel, make certain the timing is exactly correct. Go back through the steps if you are not sure it is right. Also make sure all your sensors are hooked up and working. Hope this helps. Rate me high, please. I can be requested as well if you need further assistance.
