Question about 2004 Oldsmobile Alero
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?
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

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.
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!
