Replying to: kcobain03 (Nov 20, 2007 1:34 pm) Had the same trouble with my Chevy Lumina. It is likely to be your Crankshaft position sensor. There is a trick to removing it. Let me know if you need help. Art.
#361 of 431 ecm location by mtrident Dec 17, 2007 (6:21 am)
Hello, can anyone tell me where the ecm is located? I have power to the engine and a/c relays when thy are removed, but lose it when they are plugged in. I checked the relays with my meter and battery and they seem fine. I suspect there is something on the ecm allowing power but no current. Does this sound like the ecm? I'd like to change it but need to know where it is. Thanks! Replies to this message: kframe (Dec 17, 2007 5:37 pm) mtrident (Dec 21, 2007 5:42 am)

Replying to: mtrident (Dec 17, 2007 6:21 am) Just checked my factory service manual and it says that the ECM is located under the instrument panel on passender side. Probably behind glove box. Never had to find mine so I dont know first hand. Let me know how it goes. Art. Replies to this message: mtrident (Dec 21, 2007 5:42 am)

Replying to: kframe (Dec 17, 2007 5:37 pm) That's where it is alright. I haven't a clue how I'd get it out as there is almost no roo,. It looks like the glove box has to come out. In any case, I found out it is the intake gasket causing the problem, so I'm changing that this weekend. Thanks for the response! Dave
#366 of 431 overheating by berkiespop Jan 02, 2008 (7:24 pm)
My 99 century is overheating and I have changed the water pump and thermostat and bled the system and it is not leaking water (visibly) but it still overheats. I took it to a radiator shop and spent $158 on sensors and testing fan circuits and all is ok, but it is still overheating. Can anyone help me before "I" overheat?!

Replying to: berkiespop (Jan 02, 2008 7:24 pm) To berkiespop: Yes I have had a similar problem on a Lumina which caused a leaking head gasket! When replaced I found blocked water jackets around some cylinders. What was it blocked with you might ask? That famous Leak stopper crap that they sell. I had used this stuff to stop a leak, and it stopped it all right, along with blocking essential water passages! If you used this stuff I would think that you have the same problem. Try to flush out the system using Prestone radiator flush. Several times if needed. Also Back flushing is the best way to do this. I cant believe that a radiator shop didnt do this for you. I hope that is your problem, and that you get it cleaned out alright. Replies to this message: berkiespop (Jan 03, 2008 1:27 pm)

Replying to: kframe (Jan 03, 2008 4:50 am) I have used that stop leak and that is probably my problem. Thanks a million!
