2001 alero new timing chain and coils

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?

Hi Angiebaby,

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 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

99 Dodge Intrepid 2.7L no power to ignition. Receiving Code P1684 but battery connection okay.

I have a problem with a 1999 Dodge Intrepid 2.7. Looking for some help or suggestions.

Problem: I only have a spark from the #2 coil.


Vehicle purchased from an Auction and would not start. The vehicle would only backfire. When I removed the valve covers I found that one of the rocker arms had popped out. I replace the heads with heads from a 2001 Intrepid 2.7. I used the cams, primary and secondary timing chains from the 1999 heads. Not sure if I used the original primary (left) cam sprocket from the 1999 or one I purchased in a kit from a Dodge dealership. I tried to use the new primary timing chain but it was not the same. The replacement heads were surfaced and a new head gasket was used. When I tried to start the vehicle it had no spark. The vehicle had set at several locations and parts may have been removed or changed.

Solutions Tried:

I tried 4 ASD relays with no effect. I then tested all 4 on a 2002 Intrepid 2.7 that runs and all worked. I then discovered that the Crank PS has missing. I replaced the Crank PS with one from a 2002 Intrepid 2.7 with no effect. I then replaced the Crank PS with a Crank PS from a 1999 Intrepid 2.7 and got a spark at the #2 coil only. I then replaced the PCM and TCM from the same 1999 Intrepid I got the Crank PS from and still only have spark from #2 coil. I then changed the Cam PS, still spark only from #2 coil. I have tried several coil packs on connector #2 and all have spark. Each coil pack that sparks on #2 will not spark on any other connector. Spark from #2 coil is weak.

I then replaced the wire harness from the PCM to the coils and fuel injectors and still only have spark from the #2 coil. What am I missing? Any suggestions, advice or related information will be greatly appreciated!

Where are the timing marks on a 2001 Oldsmobile Alero?

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

Should it cost a grand to replace the timing chain+3 guides

$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.

2001 old alero turns over will not start

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.
