Hello and good day!
I am changing the spark plugs and wires for a 96 Pontiac Bonneville. Since I have changed them, the car will not start. I think that we have got the wires crossed upon reinstalling them. We have since purchased the Haynes Repair Manual, but it basically tells us that we shouldn't be doing the work ourselves... We should have taken them off one by one. Unfortunatley, the book does not come with a diagram. Can you tell me what order the plugs should be attached to the ingnition coils?
Thank you!
