87 4000csq starting problem
I have a strange starting problem that seems to be the result of a sparkplug swap. Seeing as how the car has about 177,000 miles on it, I thought it'd be a good idea to swap the plugs out with some new bosch platinum2's. After I swapped the plugs, however, the car would no longer start. I put the original plugs back in, and still nothing. This morning I went out to try it before work and after a brief hesitation, it started, so I let it run for a couple minutes. Not wanting to run the risk of getting stuck at work, I turned it off to try and start it again, but I got nothing. While it was running, it sounded normal, idled smoothly at about 1K, but it just won't start again. The threads in the plug holes look a little rusty, so I thought there might be too much electrical resistance for it to spark properly, but since it ran smoothly the one time, now I'm unsure. Any ideas as to the possible cause and/or a good solution for cleaning the spark plug holes? Thanks.

Re: 87 4000csq starting problem
Rusty spark plug holes should not cause the plugs to not fire. Before you get crazy or do anything too nuts, go to the 4000 forum and ask the members there.
Chances are it is not the plugs at all, but a coincidence that occurred at the same time as your plug swap.
You are in good hands though. Collectively, there is an enormous amount of experience at your disposal. Ask the 4K forum members, and also, run a search of the forums. If it is happening to you, there is a 100% chance others have had it happen, and you may find the answers have already been posted.
Good luck
