I changed my exhaust yesterday, I have done it in the past with out and issue. I got everything back together and went to start it, it cranked over but would not start. I checked my connections they were all good so I check the spark plugs, I had no spark. I then checked the coil and had no power to the coil. I checked the engine codes and got the following: crank sensor/circuit; tps sensor/ciruit; manifold air temp sensor/circuit; distributor sync/ circuit. I checked all fuses and relays, they were good. All of the grounds also look fine.
Thanks

Check the injectors connector -dark green and black wire for power no power there also could mean a defective ASD relay-The ASD relay powers the coil.

I get power to the injector for a split second when engine is first cranked over but then nothing. Switched out the auto shutdown relay and still no spark.

Power the coil from the battery and see what happens.
