I have a 1993 Lumina APV that isn't firing any spark plugs. It actually hasn't been started in about 3 years. I've jumped the battery and it cranks fine and I just put new plugs and wires in but none of the spark plugs are firing. This is also not a result of it sitting for so long, it sat for so long because of the firing problem and was just never fixed. What could it be?
Much easier if a 3.1 though: it is all in and around the distributor.
reading the codes can give some indication, although not always critical of the actual problem. IN any case, use this: www.avigex.ca/xport/readingcodes.jpg
