This is a 95 Cadillac DeVille that has 187000 miles on the odometer, and with the 4.9L V8 that was running well and then one morning it would not start. It will turn over strong when the key is turned but it won't fire. Pulled the fuel line just before the fuel regulator and the fuel comes out strong when turning key to start. Checked the fuses that had to do with the ignition and fuel injectors and they check good. I pulled the plastic cover off the distributor and found what looked like the coil. Checked the plug and contacts and there is no voltage to the coil when turning key to start position. I went ahead and made a guess to change out the ignition module inside the distributor housing and that did not fix it. I have checked the codes and the codes I have recorded are as follows:
P052
P065
I039
I052

Could you give me an idea where to go from here?
Thanks in advance for any ideas.
