Let's just start this off with the obvious. I'm not disappointed in the car but myself for letting it get to this point.

Life happened and I ended up not running the SS at all last year. Last drive was fall of 2017 before it was put away for winter, then my daughter was born and just didnt find the time. I am almost positive I stored her with stabil 360 as evident by a half empty bottle on the shelf but who knows. Went to start her in Jan. Wouldn't do it. She turned over and acted like ahe was going to catch but then nothing. Smelled gas out of the tailpipe and figured she was flooded. Went at it today and poored a small amount of fuel down the carb first and tried again. Nope not going to start. Didn't even act like she was going to fire. Gave up again when i smelled fuel. She is stored in a garage with a battery tender on at all times. I would think shed start and run like crap if it was the gas but what am I missing? I'm about to the point to throw the towel in and find a shop and have it towed and worked on to get her spring ready this year. Since my daughter is 16 months now, I'd like to start early getting her into my hobby.

Check for spark. Take a plug wire off stick a phillips screwdriver in the end and hold close to a good ground. Let someone turn the engine over while you look for a blue spark.
The engine does turn over fast, yes ?

The HEI system is so powerful, it can give false good readings with traditional spark tests. You need a special HEI tester with a built in resistor.

Check to see if the choke is closing? Also check the aircleaner for mouse nests clogging it. Mice love engine aircleaners.

Air cleaner is free. It turns over normal to me (no different than it ever has). I'll check the spark plugs next. I have new ones so I might just have to put them in (well all new electrical parts for the car - that was going to be a refresh to help her run better). Choke appears to be closing normally as well.

Good to check plugs (old, worn or dirty?) and distributor/points (clean and dry)? Was it stored in a garage or???

Dry garage. I'm betting the electrical system just gave up the ghost. I thought it was going to be the next thing that went wrong hence why I puchased all new electrical parts (distributor, coil, plugs, and plug wires). Just upsetting. My dad keeps pushing for me to LS3 swap it because of the reliability and overall power and I'm trying to justify keeping numbers matching with tasteful power enhancements.

You are perhaps psychic? Some parts die slowly others overnight. or at least over 18 months. Tempermental and wanting more of your attention I think. If you haven't updated the electric and you have it all on hand its just an hour or two. Sounds like you have everything in hand. Nice pictures too. Thanks for sharing. Keep us posted.

Air, fuel and spark... three things needed for internal combustion.

I had an ignition module fail a couple years ago. Ran when parked in the fall, no spark when starting it in the spring.

I liked the mirrors, lol. Agree with Frank above, very well could be an IM fail.

When replacing the ignition module, be surd to coat the bottom with heat transfer paste, not dielectric grease.

I've used dielectric grease and never saw or had a problem. It also doesn't dry out like heat paste.

Funny. But I really don't think that's the answer to his problem.

The MSDS sheet for Permatex dielectric states "Conditions to Avoid: Heat." Di = anti, dielectric is non conductive, an electrical insulator, not really designed to be a thermal conductor. It is designed to keep moisture out of electrical connectors while insulating possible short pathways to ground. It lacks heat transfer agents. Some types of dielectric grease are even heat resistant, not heat conductive.

Heat paste, the good stuff has silver in it to transfer heat. Its designed to be use very sparingly to fill micro gaps between two surfaces to eliminate micro airgaps which interfere with heat transfer. Even heat paste conducts heat less well than direct metal contact, which is why it must be use so sparingly.

Well my Dad would say LS swap since it doesnt start but he is in love with the LS motor in his Vette.

Is that the ignition module and does it require the distributor to be disassembled for installation? Sorry for dumb questions I'm out of town away from my service manuals. The diagram I found on a GM parts page led me to down this path and it looks awful to work on.

Put the new spark plugs in it. I had a similar situation. It was the plugs

The module can be replace just by taking off the cap and rotor, Unplug it and remove/replace. The module can be tested with a Volt/Ohm meter (VOM) but I'm sorry can't find that info as of now.

Maybe a silly question but I just went through this myself - did you have the battery load tested? Mine started going only one trip on a charge. Then this morning, after charging it all night, I was about to take it to the GM dealer to have it warranty replaced (only 1 1/2 years old on 3 year warranty) and it wouldn't start. Luckily by putting the charger back on and cranking, it had just enough juice to get me started. No arguments at the dealer - they proved it was bad and swapped it out for $25 labor.

I haven't load tested the battery. Starter gets enough juice to crank at a normal sound for the car and didn't act like a dead battery (had one a couple of years ago that was just weak - would start after an overnight charge but that's it.

Just have to get up the courage to try the ignition module and plugs. Engine stuff scares me. It's one of the reasons I've got parts sitting om the shelf waiting. I'm not a mechanic and if never worked on one before.
