1994 Lesabre wouldnt start so i tried to jump it; ended up blowing something.

[lesabreprinters]

My lesabre is pretty unusual for the '94 variety, it sat for 10 years under a car port and only started driving last year. Current mileage is a little under 54000. When I first got it I had to get the master brake cylinder, gas lines and tank, as well as the battery replaced and some belts. Been driving pretty fine over the past year, but today I went out to go to work and when I put the key into the ignition the chimes that you hear when the power turns on sounded weak and jumpy, and the car wouldn't turn over, nor would the headlights come on. So I wait a few hours for my roommate to get back and help me jump it off. We get the jumper cables attached and ready to crank and as soon as I turned the key to crank something popped in the engine compartment and started smoking. I can only describe the smell as one of those cap guns that's just been popped. Since I was in the car I didn't get a good look at where it happened so I followed my nose and it was most concentrated right here. What did I do, and how can I fix it?

Did you incorrectly attach the cables?
Those are the ignition coil packs and ignition control modules in the picture.

I had them as snug as I could get them, I think one of them might be a little rusty but that's never caused too much of an issue for me before if since i used some type of solenoid gel on or what ever it is on the leads to help increase the connectivity.

You misunderstood my question.
Were the jumper cables attached black to black and red to red?

Yes, they were connected properly

Unfortunately no one may know what you did, so it's probably best to just start looking in the area where you suspect it at for melted, shorted or burnt wires along with connections including the battery cables at the vehicle connections not the battery.

Presumably you blew a fuse somewhere and you should locate which one it is.

Side post terminals can corrode and loosen. Be sure that all that connection & terminals are clean & tight.

If the bolts have never been replaced they may not be tightening to the battery properly. You can cut the sheaths slightly and slip new bolts in. It does seem sort of unusual to just happen randomly unless the battery isn't really secure and just flopping in the wind. Also check that the ground cable going down from the battery is still fastened well. A wire brush may be your friend.

It's looking like I blew out the ignition coil for 5 and 6. I just got a replacement and I'm going to be replacing all of the spark plugs, but the bolts holding the ignition coil are so old I can't seem to get them off without damaging them to the point of not being able to be put back on. What size bolts would work as a good replacement? I'll be replacing all three coils hopefully soon but I could only afford the one right now.

Here's the specs on the coil bolts
BOLT,IGN COIL(HEX WA HD,M4.5X.75X34.5, 28 THD,10.6 OD,GM 6171,GM 1345,TAP)(2.383)(ACDelco #10470758)

I was surprised at all of the metric hardware so make sure you are using the right socket. M4.5

That's the diameter of the bolt thread not the size of the head of the bolt.

 

[sightcrr]

After I typed that I looked at a scale and thought that seems small. Sorry I gave you bum info. Sightcrr

I'm finding this to be my Biggest hurdle now, all the tools I have are imperial measurements so nothing I'm trying seems to be working. I even borrowed a spark plug socket with a 13/16th" head and 3/4", but neither of them fit. It's the same with the bolts holding down the ignition coils, its somehow in-between 3/16" and 1/4". What tools do I need now that I have most of the parts?

 

[2007LucerneCXL]

Metric and/or US standard would be the only sizes you would be using. Some sizes are close in both standards but most on any GM vehicles are metric since the started the conversion around 1979.

This confuses me even more now, why are none of the tools I have that should fit working? The spark plug socket I have should fit but neither side seems to be catching the bolt. Same with the bolts on the ignition coil, the 1/4" is just barely too big and the 3/16" is just barely too small! I feel like I'm going insane trying to get this taken care of. Thank you all for your help and words of advice though, I'd be even more lost without it. I dont know what to do

 

[2007LucerneCXL]

Metric

 

[MelsRegal]

Between 1/4" and 3/16" is 7mm

Thank you. Smallest I have is 10mm so it looks like I've got more shopping to do
