There is a 4.1 or 5.7. So here is a 4.1, In the fuse panel is battery fuse this is hot at al times,regardless if the key is on or not.This power goes to the ECM Pin 10 and 15. If power is verified then your problem is internal of your ECM.(they are prone to have weak solder joint causing all sort of problem with the module)
If you can verify that you have power going in and still no start then you will need a ECM.
Code 52 is CALPAK error. You need to inspect the pins and make sure its seated in its socket.Code 52 does not create a no start. Check for spark and fuel.
Well your right . I checked all the wires in the dist. Made sure I had no opens or shorts to ground. Installed a new ignition moudle and coil ( just for haha's ) Checked all the pwer leads to the ecm and grounds to the engine and body. Checked all the fuses and pins behind them . Then thought the new ecm was bad , that happens sometimes . Installed a known good one from a running car and still nothing . At this point I'm ready to just junk it. If it wasn't for the fact it's almost mint I would
Dont junk it.Lets get away from faulting the ECM. Lets check spark You need to know that the Cadillac eldorado is famous for its distributor gear drive failure so even if you have spark is it firing at the right time and location? So pull a plug wire have some one crank it as you hold the spark plug close to engine ground. If there is spark that is a good thing. If there is no spark is the distributor turning?Take the distributor cap off and crank the engine does the distributor rotor turn? If not you will need a distributor gear drive. So take out the number one spark plug out and bring it to its compression and see if the timing marks lines up at TDC. From there is the distributor at the number one spark wire to fire it?
Check the drive gear of the distributor.That can also set code 52

I have already replaced the ecm . I thought that also. But the other thing is this code caused a no start . As far as I can tell all the power is where it should be and all the grounds check good . I checked the wires from the dist. and all the fuseable links. Still nothing. I can't clear the code no mater what I do and it will not start
I have already replace the ecm with a new one. I also thought the new one had a problem so I found a good known used one and tried that still nothing. As far as I can tell the prom is the problem . But thats a problem in itself because no one has them and I can't find a new one .
I want to thank everyone for the help. I know about the dist gear problem. The dist in the car is less then a year old. But at the same time I ordered one last week and just got it today. Thats the last part of the puzzle. If that doesn't work It mash mellow time. Again thanks
