I have a 1997 Cadillac deville,,,,,
im getting a PCM code P1376

this started after the wiring in the plug that plugs in the coil pac from the PCM was pulled free,,,I though we wired it back the same,,,obviously not,,,it will fire briefly if I disconnect the battery then hook it back updoesnt run but fires briefly then nothing

any thoughts

Thanks

 

The code is Ignition Ground Circuit Fault. So with what you said about the plug it sounds like it's wired wrong.

 

ditto ...
