BodybyFisher Posted February 16, 2009 Report Share Posted February 16, 2009 Did you make sure you installed the timing chains with the correct indexes?

ftime Posted February 17, 2009 Author Report Share Posted February 17, 2009 Did you make sure you installed the timing chains with the correct indexes? ftime; yes i did ihave look at all the things it could be maybe i need to take off the coils and get them check or just go get a code reader my check engine light is on Link to comment Share on other sites More sharing options...
BodybyFisher Posted February 17, 2009 Report Share Posted February 17, 2009 You dont need a code reader. Go to HOW TO at the top of this page, go to DTC CODES and follow the directions on how to pull the codes and post them here. I would, listen for the fuel pump, check the crank sensor connections are correct, check grounds, check ignition wire routing, recheck all connections Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

BodybyFisher Posted February 19, 2009 Report Share Posted February 19, 2009 I would immediately do a compression test. Did this mis begin immediately on start up? This is a 96, are you SURE you have all of the ignition wires routed correctly? Are you sure all of your coils are good?

BodybyFisher Posted February 20, 2009 Report Share Posted February 20, 2009 Make sure that the numbers on the coil are correct, let me post the routing Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
BodybyFisher Posted February 20, 2009 Report Share Posted February 20, 2009 Here it is, keep in mind that the two screw holes on the ICM face the rear of the car so you get proper alignment of the coil numbers. This is directly from a 96 service manual. Check all connections at the ICM including power connector Recheck the crank sensors, I dont like that you had a problem with one of the wires. PLEASE make sure that the correct wire is connected to each sensor! If you need me to look in the manual for the correct wire colors for the crank sensors let me know...

BodybyFisher Posted February 21, 2009 Report Share Posted February 21, 2009 I have never done this job. It certainly is sounding like a timing or spark issue. Did you ever check the routing. Did you check the crank sensor wires for correct Top and bottom connections? Please start responding directly to things that are suggested as its hard to know what you have and have not done. HUMOR ME.... if you checked the ignition wiring PLEASE TELL ME.. same with the crank sensor wires Hopefully one of our time serters will know the answer to your question ftime, where are you located? mike Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

Texas Jim Posted February 24, 2009 Report Share Posted February 24, 2009 You have one bank or maybe just one cam, out of time. Your cylinders 1,3,5 and 7 are ok on compression. Your cylinders 2,4,6 and 8 are all low. Therefore THAT BANK is out of time. Link to comment Share on other sites More sharing options...
BodybyFisher Posted February 25, 2009 Report Share Posted February 25, 2009 This is why I said to do a compression test immediately in my #12 post. This is not good news ftime, I am sorry. I recall the guru saying that the cam can be out 180 degrees. What did you use to set the timing chains? When you decide to do this again we will post a schematic showing the timing chain indexes...

KHE Posted February 25, 2009 Report Share Posted February 25, 2009 You really need to remove the timing cover and front cam cover and verify the cam is in proper time. The low compression is the key to the rough running. You may need to turn the crankshaft up to seven turns in order for the timing marks on the intermediate sprocket and the crank sprocket to line up. I am afraid you had it off time slightly and the valves got bent and are not sealing off. That would explain the low compression for all cylinders on the front bank but you need to verify the timing.
