Can someone tell me if these wires go to the ignition . Cause I have no fire at coil. Ran fine couple of days ago cranked it one morning and it idled awhile then went dead.

 

Go up to the faq's and find the link to download the appropriate factory service manual for your car. It will have all of the wiring diagrams in there.

Also, when you ask questions, please let us know the specifics on the car, i.e. year, model, trans type etc.
