Replacing spark plugs in 2008 grand prix - Cars & Trucks

You will have to determine the source of your no start. Highly unlikely a fuse issue. You need to find out if the vehicle has spark to the spark plugs and fuel to the injectors. If either is not there, the vehicle will not start

often times the connection inside the plug boot gets corroded and it's almost impossible to remove the wires with out damage. when this happens I gennerally replace the wires anyway this saves you problems in the long run . the sparkplug wire removalk pliers are a good investment however they are only as good if the boots themselves are not siezed up on the plugs. I have had this happen alot over the 20 years i been working on vehicles. I usually just twist and pull on the boots till they come off and not worry about damaging them because they should get replaced anyway the new plug wires have a antiseize lubricant to keep from this happening in the future

your ignition modle is the problem

take a look at this hope it helps. engine recalled about fires:

i would say professionally that youre due for service. replace all filters and spark plugs(replace with ac delco spark plugs only or you WILL trigger a check engine light for random misfire and it will still be running good).

I used to have a Pontiac in which I had to pull the front tire off and then get to the plugs by going over the A frame. Doesn't mean it will work on your Grand Prix but you might try it.
